[U-Boot-Users] Debugging U-Boot with BDI2000

[Glenson Muthedan <glenson@gmx.de>]

Hello!

I'm quite new to U-Boot and trying to get started with the
Bootloader-Stuff for some weeks now. My Board is similar to Accelent IDP
or CSB226(PXA250 with 32 MB Strataflash and 32 MB SDRAM).
U-Boot seems to crash on my board before it can output something through
the serial line. So I wanted step through U-Boot right from the very
first instruction using BDI2000 while booting. The problem is that the
information the bdi user manual gives, is quite confusing. I tried out
various configurations for BDI2000, but really don't know what to do
with the vector table in the "Mini IC" and the debug handler stuff.
The situation now is as following: The target is in debug mode right 
from the start and the PC is pointing to 0xffff0004. "go" or "ti" 
doesn't work because of access to an invalid memory address.
(My configuration file now contains a blank [INIT] section and no vector 
table/debug handler stuff in the [TARGET] part)

I'd be very thankful if someone could answer my questions:

1) Is it possible to debug U-Boot with BDI2000 (Linux host) at all?
(eg. step through the instructions)

2) Do somebody have a working configuration file for BDI2000 (Linux 
host) to be used with a PXA250-target?

Hope, you can give me at least a hint.

Regards,
Glenson Muthedan.
