Have you ever tried ChipQuik? I haven't; I'm just curious about the experiences of those who have, and to suggest looking at it if you've never heard of it.

Thanks! Yes I have tried it and is what I would probably use. It's not ideal and sometimes end up losing some of the unused pads- even with the lower heat involved which I hate (from a cosmetic point of view). Overall it's not a bad solution if not a little messy and expensive. There's also the task of aligning and resoldering with a fine tip iron that followings, which with 100 pins with .5mm pitch is no fun.

Stu

Hey Mark. I knew you had a fix for the CS4231A somewhere but I just couldn't find it. I'll give all your suggestions a try tomorrow and see what happens. Thanks!

Stu

Okay. I tried all the suggestions, but no luck. Below is bootlog after the CS4231 fix.

I'm beginning to think that the ethernet chip may have been okay. Notice that in my bootlogs up until I started lifting pins, that the ethernet chip is recognized whereas the bootlogs with the bad ethernet chips say "smc_init couldn't find card" near the end of the log. It wasn't until I disabled the pins that this couldn't find card message appeared.

Why if all 16 bits (which seem to be needed to avoid the couldn't find card message)were functional for the ethernet chip did the IDE bus not work? I've verifed that all bits of the bus are connected to the header and tried multiple drives that have been tested good.

Stu

Was there a hard disk connected when you captured the above outputs? If not, then connect one, and try again. Otherwise the lines are just floating randomly.

Thanks.

Sorry. Yes there was a hard drive connected in each case.

Stu

Mmm.. well, your changes earlier seem to have fixed the stuck lines. All of the bits seem capable of changing state now.

So.. I wonder if the control signals are getting to the IDE bus, or if perhaps those are now stuck high/low.

You'll have to probe them individually, I suspect, preferably with a scope or logic analyzer that can trigger on state change.

Cheers

Mmm musing further on this, we do know that MOST of the control signals must be working, since the ethernet chip does respond, to READs at least.

Dunno about WRITEs.

Okay, so here's the list of IDE control signals in the empeg:

RD (read) obviously not stuck.
WR (write)
BA0,BA1,BA2 (address/register select lines)
IDECS1 (chip select)
IDECS2 (chip select)

That's mostly it. A very short list.
And since the CS4231A is also not responding,
it's most likely the pins shared with that chip.

BA0,BA1 go to both IDE and CS4231A, but not to ethernet (I think).

And the IDECS1/IDECS2 lines go only to IDE,
but they are generated by the same PEEL18CV8
that also generates the CS (Chip Select) for
the CS4231A. Perhaps the PEEL chip has died.

So.. check the lines that are in common between those
two devices (IDE, CS4231A), and see if they toggle
or are just stuck.

Cheers

Thanks Mark. I haven't gotten to any logic analyzing yet, but I did notice that with the HD removed that the CS4231 appears as normal in the boot log. Simply attaching any drive to the header causes it and the boot process to fail. I wonder if it could still be a bad PEEL? We've got a bunch of them, but unfortunately they are not programmed for that application and would have to be sent out to load the applicable code.

Stu

Now I've gotten the IDE bus to work (bad traces), but there is a problem with the I2C bus now. Which apparently configures and controls the DSP because there is no sound. Since the CS4231A fix is in place, I'm guessing the lack of a functioning DSP would kill the fix as well and explain why the CS4231A is also not working.

So it's back to probing around the PEELs and passives to the DSP to see if something has died there.

Stu

Edit: I fixed the DSP and CS4231A. For some reason, the DSP reset pin was stuck low. For whatever reason, removing the fix corrected this. I tripled checked that I had it just as Mark did and it was, but anyway all seems well now.
