Hello all
I am porting RedBoot on PXA processor..
It gives me some GDB stubs after loading, on serial console
so i tried debugging by placing some diag_printf() statement. here is
the some code of my main.c file:
bist();
diag_printf("5:After power on self
test"); //no 5
#ifdef CYGOPT_REDBOOT_FIS_ZLIB_COMMON_BUFFER
fis_zlib_common_buffer =
workspace_end -= CYGNUM_REDBOOT_FIS_ZLIB_COMMON_BUFFER_SIZE;
diag_printf("5AA::In side
#IFDEF"); //5AA
#endif
diag_printf("____5BB::OUT side #IFDEF");
//5BB
for (init_entry = __RedBoot_INIT_TAB__; init_entry !=
&__RedBoot_INIT_TAB_END__; init_entry++) {
diag_printf("____5CCDD::In side FOR LOOP1");
//5CCDD
(*init_entry->fun)();
diag_printf("5CC::In side FOR
LOOP2"); //5CC
}
diag_printf("6:After init entry
function"); //no 6
user_ram_start = workspace_start;
user_ram_end = workspace_end;
do_version(0,0);
In above code it reaches upto
diag_printf("____5CCDD::In side FOR LOOP1");
but it never call
(*init_entry->fun)(); function.
I am not getting what is Happeninig in that function...?
That line is calling various RedBoot initialization functions.
My guess would be that one of them [the first one?] is failing.
Try printing the value of the entry point, then you can look
up the address in your image and find out where to debug next.
diag_printf("Calling %p\n", init_entry->fun);
