[N8VEM: 17330] PPIDE

[Harald Rau]

Hello,

I have finished my PPIDE. Now I will use it with my old CF-Card 128Mb! But
it doesn't work. PPIDETST.COM start with:

status = 50

Current LBA = 00000000
status = 50

I can enter the command >u< and >d< without problems. When i try >r< or >w<
the tool hangs in a deadlock.

When I will write data to the drive by command >f< the tool also hangs in a
deadlock.

Is my CF-Card to old, She is over 10 years old?

What does the STATUS = 50?

My next step is by a newer CF-CARD with IDE-Support.

Greeting Harald!

Hi Harald,

STATUS= is showing you the contents of the IDE status register. 50
indicates that the DRDY (Device Ready) bit is set. This is normal.

The U (spin up) and D (spin down) commands do not apply to a compact flash
card..

The 128 MB card should work fine. I have a 32MB one that works as well.

Make sure your CF adapter is jumpered for MASTER

Regards,

Max

Hello Max,

the adapter is jumpered for MASTER. The adapter get +5V from P1 N8VEM.
Yesterday i have tested the wire from 82c55 to P1 on the Board - all O.K.!
The wire from P1 to PPIDE a have also tested. Is it possible that PIO IC
82C55 not correctly work?


Regards Harald!

It sounds like the 8255 is working as it gives you the correct status.

PPIDETST is a pretty basic utility. it doesn't have any timeouts etc.

If it hangs it is probably waiting for the DRQ bit to be set. This could
be due to a few different things.

Try reading from LBA 0.

1. Enter L then 0
2. Enter R

If it comes back to the prompt then the read succeeded.

3. Enter H

This should give you a dump of the received data.

If you are still having problems, try swapping the 8255 as well as the CF
card.

Regards,

Max

Hello Max,

I've tried this workaround, here is the result!
I set the LBA to zero and enter >r<! The Tool hangs!
I enter <h>, the screen is in the attachment!

Hi Harald,

I suspect you have a faulty Flash card or 8255. Are you able to substitute
them with a replacement?

The H command just displays whatever is in memory at the time even if the R
command didn't work. Pulling the flash card probably causes the signals to
float making PPIDETST think there was a response.

Don't forget to check the 74LS14 on the PPIDE board also. It might be
faulty or perhaps incorrectly inserted.

Regards,

Max

Hi Max,

the new card gives the same result. I have already changed the IC 74LS14 -
nothing! I have observed, when i plug a IDE HD on PPIDE she doesn't turn
on, but the green LED at PPIDE lights up continuously! I will search the
error on the N8VEM!

Regards Harald!
