On the target side, the debugging stub these three subroutines:
set_debug_traps;
handle_exception; breakpoint.
You need to provide:
int getDebugChar();
void putDebugChar(int);
void exceptionHandler (int exception_number, void
*exception_address);
void flush_i_cache();
void *memset(void *, int, int).
You can check
ftp://ftp.netwinder.org/users/s/scottb/public_html/gdb/gdb_toc.html
for more info,
I am still wondering if there is someone really using gdb stub for
kernel/module
debugging on ARM?
Best wishes,
Gaixia
