Post by William R Sowerbutts
I will also prepare an image for the DX-Designs P112 board if there is any
interest.

Oh yes please! I'd love to experiment with Fuzix on my P112!

Kind regards,

Oscar.

Here you are --

http://sowerbutts.com/8bit/fuzix/2015-02-14-fuzix.zip (284KB)

Make two floppy disks, one to boot from and one with the root filesystem.

If you have a single floppy drive then at the "bootdev:" prompt you can swap
in the root floppy and type "fd0".

If you have a second floppy drive you can put the root floppy there and enter
"fd1" at the prompt.

If you have a GIDE then you could write the N8VEM disk image I posted
yesterday to a CF card and use that for the root filesystem -- enter "hda1"
at the bootdev prompt. You still need to boot the kernel from floppy.

Let me know how it goes!

Will

Hi Will,
My Mark IV is just about fully assembled. I have 17 chips to purchase, then I will be ready to smoke test this thing and make it say, "Hello Daddy!". :) I'll definitely be interested in running your Fuzix OS! Thanks for the software and your time spent in creating it.

Subject: [N8VEM: 19312] Fuzix for N8VEM Mark IV SBC

Hi

If any Mark IV SBC owner is interested in trying out Fuzix on their board, I have prepared a disk image to make this simpler.

http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip (439KB)

I will also prepare an image for the DX-Designs P112 board if there is any interest.

Download the ZIP file and extract it. You'll get a .bin file which is a disk image you can write out to any SD card or CompactFlash card. The disk image includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0 using dd (or whatever).

Once you've prepared the card, put it in the Mark IV board and reboot the system. Tell UNA BIOS to boot from the relevant unit number and it should load the kernel. Tell the kernel where to find the root file system (it's the first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.

Below is example output from booting the card on my Mark IV system. I used an SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first partition is called "hdb1".

Will, 
 
I read and downloaded the image AFTER I got your UNA bios bug
report. 
 
I am having odd problems with this release: 
    1.  (not serious)  XOFF/XON no longer works to pause output. 
    2.  Very odd SD card problems: 
 
One of my SD cards which previously worked fine seems to boot Okay
[====== etc. 
but cannot be found by startup: 
... 
Enabling interrupts ... ok. 
IDE drive 0: hda: hda1 hda2 
IDE drive 1: ide timeout, status=0000 
SD drive 0: no card found 
bootdev: 
 
"no card found" just after a seemingly successful boot from the
card??? 
The BIOS detects the card and gives coherent firmware, date-code,
and size information.  Plus the boot seems to work; all the
copyright messages come out. 
 
Switching to another card, same size, purchased as part of the same
lot of SanDisk cards, I can get further: 
... (same as above, then:   ) 
SD drive 0: hdb: hdb1 
bootdev:  hdb1 
Mounting root fs (root_dev=17): OK 
Starting /init 
sd: failed, retrying.                                  <-- this
message comes out frequently during system operation 
init version 0.8.1ac 
-= FUZIX =- 
 
Log in as "root" 
login: root 
 
Welcome to FUZIX. 
sd: failed, retrying.                        <-- consistent at
this point 
ssh# 
 
 
The "sd: failed, retrying." message sometimes shows up during a "ls
-l", sometimes not. 
 
I haven't tried the IDE card yet, since I don't want to lose what is
on it in other partitions.

Will,
I read and downloaded the image AFTER I got your UNA bios bug report.
1. (not serious) XOFF/XON no longer works to pause output.

Just tested (on P112) and it works. Did you enable it with "stty ixon" first?

One of my SD cards which previously worked fine seems to boot Okay [====== etc.
...
"no card found" just after a seemingly successful boot from the card???

The Fuzix sd driver will re-initialise the card -- that is probably what's
failing.

sd: failed, retrying. <-- this message
comes out frequently during system operation

Ugh. This will be fun to debug.

I'll contact you off list with some tests to run.

Will

My cockpit error.  I forgot this command. 
 
Yes, XOFF/XON works fine.

Hi Will,

I'm not running unabios so I am looking for an alternative way to boot.
The README file in the platform-n8vem-mark4 directory talks booting from
CP/M using a fuzix.com file.

I'm trying to build the kernel (downloaded from GitHub) but I am getting
the following error:

tools/binprep
Code1: 19232 bytes
Code2: 16261 bytes
Code: 35493 bytes
Data: 8639 bytes
BSS: 0 bytes
Initialized: 128 bytes
Free memory begins at: ae05
Common is at: f000
Space: 16891 bytes
Work room: 16763 bytes
Move _DISCARD down by at least 210 bytes
make: *** [fuzix.bin] Error 1

How does fuzix's boot work? Is it possible to transfer a number of sectors
into RAM and then pass control to the boot code?

Thanks!

Max

Hi
If any Mark IV SBC owner is interested in trying out Fuzix on their board, I
have prepared a disk image to make this simpler.
http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip (439KB)
I will also prepare an image for the DX-Designs P112 board if there is any
interest.
Download the ZIP file and extract it. You'll get a .bin file which is a disk
image you can write out to any SD card or CompactFlash card. The disk image
includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0
using dd (or whatever).
Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's the
first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I used an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

Max, 
 
The UNA boot code is what you would expect: 
 
Load sector 0 of the disk at 0x8000; 
check for DOS boot flag 0xAA55 (0x55 0xAA) in loc 510; 
check that it is Z80 boot with a JR (0x18) or JP (0xC3) in location
0; 
jump there (loc 0 of buffer; absolute 0x8000) with UNA bios drive
number in the L register.

If any Mark IV SBC owner is interested in trying out Fuzix
on their board, I 
have prepared a disk image to make this simpler. 
 
Â  <a moz-do-not-send="true"
href="http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip"
target="_blank">http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip</a>
(439KB) 
 
I will also prepare an image for the DX-Designs P112 board
if there is any 
interest. 
 
Download the ZIP file and extract it. You'll get a .bin file
which is a disk 
image you can write out to any SD card or CompactFlash card.
The disk image 
includes the partition table, boot sector, Fuzix kernel, and
a root filesystem 
-- everything you need. Just write it onto the raw card
starting at sector 0 
using dd (or whatever). 
 
Once you've prepared the card, put it in the Mark IV board
and reboot the 
system. Tell UNA BIOS to boot from the relevant unit number
and it should 
load the kernel. Tell the kernel where to find the root file
system (it's the 
first and only partition on the card), log in as root, have
a poke around! 
There's lots of bugs left to find and fix. 
 
Below is example output from booting the card on my Mark IV
system. I used an 
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb
so the first 
partition is called "hdb1".

Thanks John,

Looks like there is some additional code it leverages some additional
run-time code. I'll have to experiment a bit.

Cheers!

Max,
Load sector 0 of the disk at 0x8000;
check for DOS boot flag 0xAA55 (0x55 0xAA) in loc 510;
check that it is Z80 boot with a JR (0x18) or JP (0xC3) in location 0;
jump there (loc 0 of buffer; absolute 0x8000) with UNA bios drive number
in the L register.

Hi Will,
I'm not running unabios so I am looking for an alternative way to
boot.Ã The README file in theÃ Ã platform-n8vem-mark4 directory talks
booting from CP/M using a fuzix.com file.
I'm trying to build the kernel (downloaded from GitHub) but I am getting
tools/binprep
Code1: 19232 bytes
Code2: 16261 bytes
Code: Ã 35493 bytes
Data: Ã 8639 bytes
BSS: Ã 0 bytes
Initialized: 128 bytes
Free memory begins at: ae05
Common is at: f000
Space: 16891 bytes
Work room: 16763 bytes
Move _DISCARD down by at least 210 bytes
make: *** [fuzix.bin] Error 1
How does fuzix's boot work?Ã Is it possible to transfer a number of
sectors into RAM and then pass control to the boot code?
Thanks!
Max

Hi
If any Mark IV SBC owner is interested in trying out Fuzix on their board, I
have prepared a disk image to make this simpler.
Ã http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip (439KB)
I will also prepare an image for the DX-Designs P112 board if there is any
interest.
Download the ZIP file and extract it. You'll get a .bin file which is a disk
image you can write out to any SD card or CompactFlash card. The disk image
includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0
using dd (or whatever).
Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's the
first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I used an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

Hi

The boot sector code for Fuzix relies on UNA BIOS services to read in disk
sectors etc. It won't work unless UNA BIOS is present.

If you're running some non-UNA based system on the Mark IV your options are
to write your own boot sector, or to use the CP/M .COM version of the kernel.
I suggest the latter is much simpler.

The .COM loader may still fail in some cases -- it may make some assumptions
about how the MMU is configured that do not hold true in your case. If the
.COM loader does weird stuff or nothing at all please send me the values of
the MMU CBR, BBR and CBAR registers.

Thanks John,
Looks like there is some additional code it leverages some additional
run-time code. I'll have to experiment a bit.
Cheers!

Max,
Load sector 0 of the disk at 0x8000;
check for DOS boot flag 0xAA55 (0x55 0xAA) in loc 510;
check that it is Z80 boot with a JR (0x18) or JP (0xC3) in location 0;
jump there (loc 0 of buffer; absolute 0x8000) with UNA bios drive number
in the L register.

Hi Will,
I'm not running unabios so I am looking for an alternative way to
boot.Ā The README file in theĀ Ā platform-n8vem-mark4 directory talks
booting from CP/M using a fuzix.com file.
I'm trying to build the kernel (downloaded from GitHub) but I am getting
tools/binprep
Code1: 19232 bytes
Code2: 16261 bytes
Code: Ā 35493 bytes

Move _DISCARD down by at least 210 bytes
make: *** [fuzix.bin] Error 1
How does fuzix's boot work?Ā Is it possible to transfer a number of
sectors into RAM and then pass control to the boot code?
Thanks!

Hi
If any Mark IV SBC owner is interested in trying out Fuzix on their board, I
have prepared a disk image to make this simpler.
Ā http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip (439KB)
I will also prepare an image for the DX-Designs P112 board if there is any
interest.
Download the ZIP file and extract it. You'll get a .bin file which is a disk
image you can write out to any SD card or CompactFlash card. The disk image
includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0
using dd (or whatever).
Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's the
first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I used an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

Yes I was thinking about that.

At the moment I set the common base to 32KB (8000h) CBAR=80

I set the common page to the last ram page (CBR=0f0h).

The ram banks start at 0.(BBR=0)

I should move to a 16KB common as 32KB is too big.

Cheers!

Hi
The boot sector code for Fuzix relies on UNA BIOS services to read in disk
sectors etc. It won't work unless UNA BIOS is present.
If you're running some non-UNA based system on the Mark IV your options are
to write your own boot sector, or to use the CP/M .COM version of the kernel.
I suggest the latter is much simpler.
The .COM loader may still fail in some cases -- it may make some assumptions
about how the MMU is configured that do not hold true in your case. If the
.COM loader does weird stuff or nothing at all please send me the values of
the MMU CBR, BBR and CBAR registers.

I think that's a problem; The kernel assumes that BBR=CBR on entry, ie the
kernel has been loaded into contiguous physical memory.

Relevant code is "z180_init_early" in here:
https://github.com/willsowerbutts/FUZIX/blob/master/Kernel/cpu-z180/z180.s

Post by Max Scane
The ram banks start at 0.(BBR=0)

Really? Not at 512K ie BBR=0x80? That is where RAM normally starts on a Mark
IV, since ROM is in the low 512K -- unless you are using a RAM board on the
ECB bus?

Will

Post by Max Scane
Yes I was thinking about that.
At the moment I set the common base to 32KB (8000h) CBAR=80
I set the common page to the last ram page (CBR=0f0h).
The ram banks start at 0.(BBR=0)
I should move to a 16KB common as 32KB is too big.
Cheers!
Max

Post by Max Scane
Thanks John,
Looks like there is some additional code it leverages some additional
run-time code. I'll have to experiment a bit.
Cheers!

Yes you are right. RAM starts at 80h. I was looking at the N8 init code.

Cheers!

I think that's a problem; The kernel assumes that BBR=CBR on entry, ie the
kernel has been loaded into contiguous physical memory.

Post by Max Scane
The ram banks start at 0.(BBR=0)

Really? Not at 512K ie BBR=0x80? That is where RAM normally starts on a Mark
IV, since ROM is in the low 512K -- unless you are using a RAM board on the
ECB bus?

If you're running some non-UNA based system on the Mark IV your options

to write your own boot sector, or to use the CP/M .COM version of the kernel.
I suggest the latter is much simpler.
The .COM loader may still fail in some cases -- it may make some assumptions
about how the MMU is configured that do not hold true in your case. If

Thanks John,
Looks like there is some additional code it leverages some additional
run-time code. I'll have to experiment a bit.

Max,
Load sector 0 of the disk at 0x8000;
check for DOS boot flag 0xAA55 (0x55 0xAA) in loc 510;

Hi Max

You can indeed boot two ways, either from a disk, or from a CP/M .COM file.
In both cases the kernel image (fuzix.bin) is loaded into memory from 0x88
upwards and we then jump to this address.

The disk boot sector uses UNA BIOS calls to load the data from disk by
itself. In contrast the .COM has a stub loader program followed by fuzix.bin
as a trailer; CP/M loads both and the stub then does some juggling to get
itself out of the way and move the kernel to the right address.

Source code for each, if you're interested:
https://github.com/willsowerbutts/FUZIX/tree/master/Kernel/cpm-loader
https://github.com/willsowerbutts/FUZIX/blob/master/Kernel/platform-n8vem-mark4/diskboot.s

The downside to the .COM approach is that everything must fit into the CP/M
TPA which, as the kernel grows, is getting tight!

Here's a .COM file you can try to boot with:
http://sowerbutts.com/8bit/fuzix/fuzix-5290f55.zip

As to the build error -- you're building from Alan's tree. Try building from
mine instead;
https://github.com/willsowerbutts/FUZIX

Here's what's going on -- The kernel has some code that is required only at
boot time. This code goes into a segment called _DISCARD. After
initialisation, the memory from this segment can be reused for data storage.
In Alan's tree that segment is limited to 4KB in size, but the code in there
has grown over 4KB, hence the failure you're seeing -- _DISCARD starting at
0xE000 would overlap the _COMMONMEM segment starting at 0xF000.

In my tree the _COMMONMEM segment starts higher up at 0xF800 so _DISCARD can
be up to 6KB, hence no problem.

Thanks for reporting this, I hadn't spotted that _DISCARD had grown so large.
I've been holding my _COMMONMEM change back while I tested it, it does seem
to be reliable so I will push it upstream to Alan today.

Thanks

Will

Hi Will,
I'm not running unabios so I am looking for an alternative way to boot.
The README file in the platform-n8vem-mark4 directory talks booting from
CP/M using a fuzix.com file.
I'm trying to build the kernel (downloaded from GitHub) but I am getting
tools/binprep
Code1: 19232 bytes
Code2: 16261 bytes
Code: 35493 bytes
Data: 8639 bytes
BSS: 0 bytes
Initialized: 128 bytes
Free memory begins at: ae05
Common is at: f000
Space: 16891 bytes
Work room: 16763 bytes
Move _DISCARD down by at least 210 bytes
make: *** [fuzix.bin] Error 1
How does fuzix's boot work? Is it possible to transfer a number of sectors
into RAM and then pass control to the boot code?
Thanks!
Max

Thanks Will, I'll give it a try. I'm travelling this week so I may not get
to it until the week-end.

The whole project is looking very interesting. Eventually I'd like to port
it to the Multicomp but I think we will need to improve the interrupt
system first.

Cheers!

If any Mark IV SBC owner is interested in trying out Fuzix on their

have prepared a disk image to make this simpler.

I will also prepare an image for the DX-Designs P112 board if there is

interest.
Download the ZIP file and extract it. You'll get a .bin file which is a disk
image you can write out to any SD card or CompactFlash card. The disk

image

includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at

Once you've prepared the card, put it in the Mark IV board and reboot

There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I

Hi
If any Mark IV SBC owner is interested in trying out Fuzix on their board, I

includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0
using dd (or whatever).
Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's the
first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I used an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

Will,

How does FUZIX compare to UZI180 for the P112?

UZI180 is an ancestor of FUZIX. I started with the UZI180 kernel and ported
it back to pure Z80 and added drivers for it to run on my socz80 FPGA
computer. UZI180 built using the CP/M version of the HiTech C compiler,
either under real or emulated CP/M; this was rather restrictive, so I updated
it to ANSI C and ported to the modern SDCC compiler, building under Linux.

Alan then merged UZI-socz80, UZIX, and possibly some parts of other UZI forks
and added a large number of improvements of his own to create the base for
FUZIX. The on-disk filesystem structures have been extended in incompatible
ways (eg, 30 character file names), the system call API has been modernised,
and the kernel has been improved with a number of extended or additional
features. The userspace libraries and utilities have been completely replaced
or reworked.

FUZIX is portable -- the same source tree builds for multiple Z80, Z180,
6502, 6809 and 68000 machines.

On the P112 specifically Fuzix has driver support for the ESCC, ASCI and
16550 UARTs, the floppy controller, the real time clock and the optional
G-IDE expansion board. It has much more efficient task switching.

There remain a number of bugs but they are getting fixed at a steady rate.
In contrast UZI180 probably has fewer bugs but I don't believe anyone is
working on fixing them at this time.

Will,
How does FUZIX compare to UZI180 for the P112?

Hi
If any Mark IV SBC owner is interested in trying out Fuzix on their board, I
have prepared a disk image to make this simpler.
http://sowerbutts.com/8bit/fuzix/2015-02-13-fuzix.zip (439KB)
I will also prepare an image for the DX-Designs P112 board if there is any
interest.
Download the ZIP file and extract it. You'll get a .bin file which is a disk
image you can write out to any SD card or CompactFlash card. The disk image
includes the partition table, boot sector, Fuzix kernel, and a root filesystem
-- everything you need. Just write it onto the raw card starting at sector 0
using dd (or whatever).
Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's the
first and only partition on the card), log in as root, have a poke around!
There's lots of bugs left to find and fix.
Below is example output from booting the card on my Mark IV system. I used an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

Will, 
 
Hearing you mention 30 character filenames makes me ask if the Fuzix
filesystem is the same as the Minix 2 filesystem?  (Perhaps only the
30 character filename limit is the same.)

How does FUZIX compare to UZI180 for the P112?

I will also prepare an image for the DX-Designs P112 board if there is any
interest.

Download the ZIP file and extract it. You'll get a .bin file which is a
disk
image you can write out to any SD card or CompactFlash card. The disk
image
includes the partition table, boot sector, Fuzix kernel, and a root
filesystem
-- everything you need. Just write it onto the raw card starting at sector
0
using dd (or whatever).

Once you've prepared the card, put it in the Mark IV board and reboot the
system. Tell UNA BIOS to boot from the relevant unit number and it should
load the kernel. Tell the kernel where to find the root file system (it's
the
first and only partition on the card), log in as root, have a poke around!

There's lots of bugs left to find and fix.

Below is example output from booting the card on my Mark IV system. I used
an
SD card which UNA BIOS calls unit 3; Fuzix calls it /dev/hdb so the first
partition is called "hdb1".

I expect there is similarity in the data structures, but they are different
filesystems.

W

Will,
Hearing you mention 30 character filenames makes me ask if the Fuzix filesystem
is the same as the Minix 2 filesystem? (Perhaps only the 30 character filename
limit is the same.)

UZI180 is an ancestor of FUZIX. I started with the UZI180 kernel and ported
it back to pure Z80 and added drivers for it to run on my socz80 FPGA
computer. UZI180 built using the CP/M version of the HiTech C compiler,
either under real or emulated CP/M; this was rather restrictive, so I updated
it to ANSI C and ported to the modern SDCC compiler, building under Linux.
Alan then merged UZI-socz80, UZIX, and possibly some parts of other UZI forks
and added a large number of improvements of his own to create the base for
FUZIX. The on-disk filesystem structures have been extended in incompatible
ways (eg, 30 character file names), the system call API has been modernised,
and the kernel has been improved with a number of extended or additional
features. The userspace libraries and utilities have been completely replaced
or reworked.
FUZIX is portable -- the same source tree builds for multiple Z80, Z180,
6502, 6809 and 68000 machines.
On the P112 specifically Fuzix has driver support for the ESCC, ASCI and
16550 UARTs, the floppy controller, the real time clock and the optional
G-IDE expansion board. It has much more efficient task switching.
There remain a number of bugs but they are getting fixed at a steady rate.
In contrast UZI180 probably has fewer bugs but I don't believe anyone is
working on fixing them at this time.
Will
Will,
How does FUZIX compare to UZI180 for the P112?

It's very close to the v7 file system but with 30 character file
names. So near enough its System 5 with half sized blocks. The big
difference to filesystems like the Minixfs are that there are no
allocation bitmaps, instead freelists are used. That allows it to run
with less metadata cached in memory and much faster than having to use
an 8bit CPU to scan bitmaps.

The tradeoff is that the v7 fs tends to fragment so the free list
needs tidying up now and then. There are also a couple of other pain
points that are well understood and have workarounds in 2.11BSD but
not yet in Fuzix. The fragmentation is less well understood for fixing
although I have some ideas. Real SYS5 fixed it by saying "Well we've
got loads more RAM and CPU nowdays so lets just load the lot into
memory as a bitmap"

I'm hoping that some kind of simple sorting logic will help keep it
reasonably sane and can be done cheaply enough in bfree(). That or use
CF and SD cards, they really don't care about seek time 8)

Hi all,

I loaded Fuzix on my new Mark IV. Boot from SD card and mount of root fs worked fine. I tried same from a CF card. Boot went fine. But the mount of the root fs, not so much. So there are som issues there.

The bug Aug reports was previously fixed but I don't think I've released an
updated CF/SD card image to allow people to use it.

Here's an updated FUZIX image which includes this (and other) fixes:

Will,

I finally got a chance to try the Mar-2015 upload of Fuzix. I am
running it from SD card and it holds up well. Unfortunately, I don't
have a spare CF card that I can sacrifice to try the IDE boot. However,
I think Aug has reported that this is working now.

Hi Will,
I'm about to solder in the last socket in my Mark IV which is the CPU PLCC socket and install the last chip - the CPU itself! This baby is almost ready to come to life! All other chips and assorted parts are onboard. I've got the PLCC socket on order along with other parts for other projects which hopefully will be here before I leave Wednesday or Thursday for the CoCoFEST being held this coming weekend in Lombard, IL. A 900 mile trip for me one way. If I should be able to get it all together in time to demo, is the below version of Fuzix the latest available or have I missed a few emails since your last email in this thread was sent? Thanks a bunch for all the work you, Alan and any others are putting into getting Fuzix online. I for one will be interested to see this come to fruition.
A 6809 version? Really? You just peaked my interest yet again! What platform does it run on? I'd like to run it on a Multicomp. Is that possible?

Hi Kip

The 2015-03-23 image is the latest I have published. It still has numerous
bugs in but it is reasonably workable.

For demos, I like the "mandel" command (draws a view of the Mandelbrot set --
you can specify the co-ordinates to draw as four parameters on the command
line eg "mandel -2 -1.5 0.75 1.5"). Also "levee" which is a vi-like editor.

6809: I believe the initial target platforms are the Dragon 32 and 64. I am
sure it could run on a 6809 FPGA target providing sufficient RAM is
available.

Best wishes

Will

Hi Will,
The Multicomp bare PCB that James is selling at $16 has room for two AS6C4008N 512KB Static Memory chips. Depending on how much room is used in the FPGA to implement the needed hardware for Fuzix, I would imagine that both chips may be able to be used. How would that much memory suit for Fuzix?

The Mark IV only has 512KB on board same as the Multicomp so it should be
OK.

The interrupt controller may need a bit more work as it uses a shared
vector for the timer as well as the serial ports. The PS2 Keyboard and and
the SD controller doesn't use interrupts at the moment.

Cheers!

Memory depends on CPU. 128k is a fair Z80 minimum if all RAM. 6809 a bit
less as the code density is higher. The MMU logic can be pretty simple ..
either CP/M style bank and common or use the top two address lines to
select one of four configurable sets of high address registers..and start
it with ROM mapped.

Neither take much FPGA space.

You can go down to about 40K ROM plus 40K RAM plus fast storage in theory.

Hi Kip

You'll want UNA BIOS in there to boot from the SD/CF card image I have
provided.

Fuzix does not use UNA or RomWBW BIOS services, but the bootstrap I have
written onto the disk image requires UNA BIOS to boot.

My suggestion is to download
http://n8vem-sbc.pbworks.com/w/file/fetch/83596870/unacpm-2014-08-01.zip and
then burn unacpm-2014-08-01/compiled/512K-ROM.bin to a 512KB ROM or Flash
part (preferably flash as it can be reprogrammed in-system), then fit that to
the board.

You could also burn that image to a 1MB part, however please be aware that
while UNA BIOS will work correctly with the Fuzix disk images and UNA CP/M
will work correctly with RAM disk and other storage devices, you will have
problems if you try to use UNA CP/M with the ROM disk. This is because the
filesystem in the ROM was built for a 512KB ROM (384KB ROM disk) whereas in a
1MB part you have a 896KB ROM disk which requires different file system
structures. I'm not sure if there is a pre-built image available for 1MB ROMs
yet.

If you produced a valid 896KB ROM disk you could build a 1MB ROM image by
taking the first 128KB of 512K-ROM.bin and appending your ROM disk to the end
of it.

Thanks

Hi Kip
The 2015-03-23 image is the latest I have published. It still has numerous
bugs in but it is reasonably workable.
For demos, I like the "mandel" command (draws a view of the Mandelbrot set --
you can specify the co-ordinates to draw as four parameters on the command
line eg "mandel -2 -1.5 0.75 1.5"). Also "levee" which is a vi-like editor.
6809: I believe the initial target platforms are the Dragon 32 and 64. I am
sure it could run on a 6809 FPGA target providing sufficient RAM is
available.
Best wishes
Will

Hi all,
I loaded Fuzix on my new Mark IV. Boot from SD card and mount of root fs worked fine. I tried same from a CF card. Boot went

fine. But the mount of the root fs, not so much. So there are som issues there.

Kip, 
 
There apparently were a series of test programs, many of which bore
the name TEST0.BIN. 
 
The page in the "SBC Mark IV board tests" folder contains a history
of the tests along with the dates they were posted.  I'd download
the zip file in that directory to make sure that you have the
latest, and most extensive test.  The zip file contains the board
setup instructions, as well as what the initial tests convey without
using the serial I/O.  Later, the serial I/O itself is tested, and
then there are some final tests which communicate on the serial
line. 
 
There is a subfolder with all of the obsolete tests archived.

Hi Will,
The PLCC68 socket came in today, and even though I forgot to get a PCB mount 4 pin HD power connector, I'm going to solder up a DC jack on wires to begin testing. :P Thank you for your suggestion. I would eventually like the bigger 1MB EPROM on board. Since this is the initial smoke test, I'll start with the TEST01.zip that John Coffman mentioned. I'll have to find that file though. I have a TEST0.bin file already. Is TEST01.zip newer? I can hardly contain my excitement to see my little Mark IV come to life!

When I brought up my Mark IV I skipped these test ROMs and went straight for
UNA.

On first power up you should observe;
- SD card light flashes at approx 1Hz for 10 seconds. There will be no other
output during this time
- After 10 seconds, you will see serial output on the RS232 port at 9600
bps, 8 bits data, no parity, 2 stop bits (yes, 2 not the more common 1)

You can then run through the setup process on the serial port.

If I didn't get the above behaviour only then I would go back and try the
test ROMs.

Good luck!

The test program will diagnose items which the BIOS will not; e.g.,
the correct operation of the SD card Write Protect and Card Detect
switches.  Incorrect operation of these switches may result in
unusual BIOS behavior which may not at first be completely obvious.

If you produced a valid 896KB ROM disk you could build a 1MB ROM image by taking the first 128KB of 512K-ROM.bin and appending
your ROM disk to the end of it.

Thanks

Hi Kip

The 2015-03-23 image is the latest I have published. It still has
numerous bugs in but it is reasonably workable.

For demos, I like the "mandel" command (draws a view of the
Mandelbrot set -- you can specify the co-ordinates to draw as four
parameters on the command line eg "mandel -2 -1.5 0.75 1.5"). Also "levee" which is a vi-like editor.

6809: I believe the initial target platforms are the Dragon 32 and
64. I am sure it could run on a 6809 FPGA target providing sufficient
RAM is available.

Best wishes

Will

Hi all

The bug Aug reports was previously fixed but I don't think I've released an updated CF/SD card image to allow people to use it.

Here's an updated FUZIX image which includes this (and other) fixes:

Did you mount device "hda1", instead of "hdb1"?  Former is IDE,
latter is SD. 
 
I don't know the state of the IDE driver code in Fuzix; it may not
be as far along as the SD card driver.
