Dear all,
follow the below email ,I use gdb-server and onboard STLINK debug the
hal_if_init() in hal_if.c file step by step,
and final, it stoped in cortexm_stub.c at
val = _registers[offset/sizeof(target_register_t)];
in function
target_register_t
get_register (regnames_t reg)
{
target_register_t val;
int offset = reg_offset(reg);
if (REGSIZE(reg) > sizeof(target_register_t) || offset == -1)
return -1;
val = _registers[offset/sizeof(target_register_t)];
return val;
}
and attached is my .ecc configure file.
anyone give me some advices,thanks a lot!
