I would like to debug from the earliest possible point pre-relocation (for educational reasons). Couple questions....
In the Makefile, where do I place the following flags... -Os #-fomit-frame-pointer -g -fno-schedule-insns -fno-schedule-insns2
I've added the flags in a few different spots, but I still can't break on cpu_init_f. Here's the output... (gdb) b cpu_init_f Function "cpu_init_f" not defined. Make breakpoint pending on future shared library load? (y or [n]) y
I assume the flags didn't get set, specifically -g.
To backup a little here is what I get when I do target remote...
(gdb) target remote 169.254.21.13:2001 Remote debugging using 169.254.21.13:2001 warning: Unable to find dynamic linker breakpoint function. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. 0x00000000 in ?? () (gdb)
I assume those warning are related to my issue above?
Also, when I power on the target, u-boot just starts loading. How do I halt it? I tried to set a breakpoint at text base in the BDI, but it doesn't halt.
