Hi, I am new to u-boot. I have few doubts. A brief explanation about my working environment:
- ARM11 based target board, having its own IP address
- PC running on RedHat Linux-8.0, having its own IP address
- BDI2000, having its own IP address
- PC and BDI2000 are connected to the network (IP address for BDI2000 is 192.168.226.159)
- U-boot is already available on target board in the flash
memory
- Firmware is already available on BDI2000
- BDI2000 is connected to the target board through
- Using gdb-6.1 configured with --target=arm-linux
The following are my doubts:
- I want to debug u-boot. So to start debugging u-boot, Do I need to
use bare target board that does not contain u-boot already ?
- I could not start debugging u-boot. So I started debugging kernel
with the target board that already contains u-boot. Please check the following:
[ravi@localhost 2.6_kernel]$ /home/ravi/gdb-6.1/temp/gdb/gdb vmlinux GNU gdb 6.1 Copyright 2004 Free Software Foundation, Inc.

Please help me ... Thanks A Lot In Advance, Ravi
I'm not an expert in the questions you ask, especially since I have not used an ARM but...
#1 (using the BDI to debug u-boot) * See DULG FAQ section
<http://www.denx.de/twiki/bin/view/DULG/WrongDebugSymbolsAfterRelocation
WRT #2 (using gdb and the BDI) * Is your IP address for the BDI correct? Can you ping it? Can you telnet to it? * Do you have a DEBUGPORT defined in your BDI config file (that is where port 2001 is defined)
