[U-Boot-Users] BDI2000 Debug

[uboot at sundmangroup.com]

Hello,
>>Can you prove this with a log of the exact steps you performed?

I am doing the following steps:

1. Rebuild U-boot 1.0.1 :: OK
2. Flash U-boot 1.0.1 to a Motorola PQ2FADS-VR board :: OK
3. Test U-boot 1.0.1 through the PQ2FADS-VR board serial interface :: OK
------------------------------------------------------------------------
BDI2000 Debug attempt 1
------------------------------------------------------------------------
1. ppc_82xx-gdb u-boot
2. target remote bdi2000:2001

_start ()
     at start.S:163
163   li r21, BOOTFLAG_COLD /* ...
(gdb) b cpu_init_f
Breakpoint 1 at 0xfff03bac: file cpu_init.c, line 106
(gdb) c
Continuing.

< Here the debug session hangs or continues forever.... >
