Hi,
I use a Lite5200 board (ref. board from Motorola). With the two PCI network
cards I tried (which I would want to use under Linux 2.4.25), u-boot
crashes:
U-Boot 1.1.2 (Jul 12 2004 - 20:10:35)

Call backtrace:
machine check
(I tried 1.1.1 first and then gave a try to the cvs version).
One network card I tried is the SMC9452TX (Marvell chip).
Two others PCI cards, not network (Maxtor SATA and USB-2.0) did not bring
any issue with u-boot 1.1.1
Is there a known issue with the PCI on the MPC5200, and more specifically
with PCI network cards ?
Or is-that with the u-boot PCI implementation for this board ?
I tried to disable the PCI from the u-boot/IceCube config file,
but then u-boot hangs up...
Any suggestion ?
Best regards,
Olivier

Try to debug this. It would be interesting to know where the crash
happens.

There is the known timing problems.

I don;t think so,. We used several network cards on the LITE5200
without problem (the most reliable card on all test systems seems to
be the EEPRO100).

Are you sure? Where does it hang?

Can I debug it without a jtag debugger ?
How could I use GDB ?

I changed the PCI to run at 66 Mhz. Then, one network card which was always
causing a u-boot crash (with the PCI at 33 Mhz) was sometimes correctly
detected
(one one 3 or 4 attempts). So things are not really better...

My mistake, sorry...

Adding printf() is often quite useful.

Well, you could enable kgdb support in U-Boot and try this... Or you
could enable BedBug support and try this...
The recommended (most efficient) way to debug the system is with a
BDI, though.

If it has syntax, it isn't user friendly.

Wolfgang,
As it happens, I'm adding a board entry for the Cogent CSB337. I'm
new to gdb debugging and am unsure on setting up the bdi2000 for this. I
have followed the steps in the bdi manual but they are quite lacking.
Do you have anything written on the typical bdi setup for debugging u-boot?
