[U-Boot-Users] MPC8272ADS and uboot program check

[Bastos Fernandez Alexandre]

Hi to all,

After some days working ok with my MPC8272ADS board, now it keeps rebooting
all the time with a Program Check report. It has arrived after a hang.

I have been checking the output as this is all the information i have at the
moment. I have realized that clock reporting is incoherent (the true one is
cpu_clk=400Mhz), so i wonder if it has any relation.

Any idea?


The output I get is:

Looks like broken hardware to me. ESD?

First of all, I would acknowleging that Wolfgang is probably right and you probably have a hardware problem.  In case that is not true, my follow-up questions and observations are...

#1 question in debugging: what changed between when it last worked and now?

Looking at the above, what is the software trying to do when all the garbage is being spewed out (just before it prints "8MB"?  What it is doing is likely related to the problem.

Did the board previously print the correct clock rate, or has it always been wrong?  Why is it wrong?

#1 rule in debugging: always fix the known bugs before hunting for the unknown, known (but discounted and ignored) bugs tend to cause additional "unknown bugs" in strange and mysterious ways.

I get the same thing when I mount a new MPC8272 part labled:
  MPC8272ZQTIEA
  400/200/100 MHZ

I wonder if the PVR value has changed for newer chips.

Is it your private port of U-Boot to 8272? If so, the problem can be in
H/W initialisation. U-Boot supports this family and MPC8272ADS since
version 1.1.1. I work with it on daily basis without any problems.

It's not the same. This error message (CPU: ### ERROR ### Please RESET

exception.

Yes, it has. You can see it at Freescale Web site.

Hi, 

>First of all, I would acknowleging that Wolfgang is probably right and you
probably have a hardware problem.

It could be. I had some problem with the Flash in the past, but there, the
board didn't start at all and kept rebooting in a few miliseconds with a
HRESET. 

> In case that is not true, my follow-up questions and observations are...

Nothing changed. The uboot version is exactly the same it was before. 

>Looking at the above, what is the software trying to do when all the
garbage is being spewed out (just before it prints "8MB"?  What it is doing
is likely related to the problem.

I don't really now what it was doing at this point. So this is the point
where I would need your help. I have tried to guess it. Has it any relation
with the CRC warning, or some other problem with SDRAM?

>Did the board previously print the correct clock rate, or has it always
been wrong?  Why is it wrong?
>

No. Previously it showed the correct clock rate (400 Mhz). I can't imagine
why this is not right. Could be some problem with the integer unit ??? SDRAM
???

>#1 rule in debugging: always fix the known bugs before hunting for the

OK. I will try to follow this method.

Please configure your mailer to quote correctly.

BOTH lines above are quotes, but only the first  line  is  marked  as
such.  This  essentially  makes  your messages unreadable. please fix
this!

I think all additional discussion is in vain. You have known hardware
problems, so it makes no sense to continue.

Don't try to understand why the failure mode is a reset in  one  case
or  a  spectacular crash in another one - when yoiur flash is failing
you must assume that the CPU is executing random data.  This  can  be
anything,  and  fail  at  any  time  andin  any way you can or cannot
imagine.

Stop here, and fix or replace the hardware.

Sorry about that. For me all this was the same line. I haven't arrived to
configure my mailer to quote this way at all (so I have to do it by hand)
:-(
Sometimes, I have some problems to send plain-text only, but this is another
discussion.

OK. I will.

[U-Boot-Users] ppc405gp PCI initialization

[Tadas]

I finaly can run linux on my ppc acess point
and the last thing left is to enable pci, does bootloader must initialize
pci controler?
I it is normal to leave that to linux?

If I do not do anything linux complains that cant alocate resource for pci,
then I added bios fixup code from walnut405,
now linux crashes if  try to load device driver, but it can enumerate pci
devices.

The questions are:
What pci initialization is nesecary for integrated ppc405gp pci bridge?
Which bard pci code is the best example to start?
Does intergrated pci initialization depends on board design?
