hi,
sorry i did not find the answer with the wiki search
so i have a reference fw with the "C" code in boot.c for example
void __attribute__((naked,noinline)) taskcreate_SsTask_my() {
asm volatile (
" STMFD SP!, {R4,LR}\n"
" MOV R1, #0\n"
" MOV R0, #0\n"
" BL sub_FFC17024\n" // KernelMisc.c:43
" LDR R4, =0x1C48\n"
" STR R0, [R4,#4]\n"
" BL sub_FFC4E494\n"
" BL sub_FFC4FB6C\n"
" BL sub_FFC4D624\n"
" BL sub_FFC48B54_my\n"
" BL sub_FFC4E750\n"
" LDR R0, [R4,#4]\n"
" LDMFD SP!, {R4,LR}\n"
" MOV R1, #0x1000\n"
" B sub_FFC524CC\n"
);
}
that makes 15 asm instructions with the last one returning ...
the disasm from the dumped (new) firmware is

now my question, the adress.txt line should be
taskcreate_SsTask_my FCC49284 15
? i am not sure about the number,
do i count the instruction number from the reference boot.c or the number
of instructions from the disassembly
thanks
