[U-Boot-Users] u-boot debugging using gdb and BDI2000

Hallo all,

we recently purchased a BDI2000 to debug some of our products. I have u-boot-0.4.0 running on our board with a MPC8245. For a first test I connected the BDI2000 and at the telnet window a can see the u-boot code (md 0xfff00100) and can single-step through it. 1) general question: I removed DRAM etc initialization from the config. file because it will be initialized from the u-boot code. Will it work that way or is DRAM access needed for proper work of BDI2000/gdb? 2) Problem: Now I start the gdb and attach it to the BDI2000 ((gdb) target remote bdi:2001) After that I cannot see the code in flash anymore - md command in telnet window returns all "0". Disassemble in gdb also returns all "0". What did I make wrong?

Thanks for your help. Torsten
