Hello,

I am working on u-boot under qemu. Debugging before u-boots relocate itself works just fine.
After relocation and reloading elf in gdb, qemu does no stop on breakpoint.
Generally I follow this instruction:

I am debuging under eclipse - I'll test with clean gdb to be sure. As I see some topics in this list, there is some work ongoing regarding self-modyfying code on arm and gdb stub.
Does someone tries to debug such applications?

Regards,
Marcin
