I'm using the soft-core Cortex-M0,keil uvision 5,vivado 14.4 i interfaced an accelerator with my arm architecture, when i do this,in vivado simulator , the HWDATA=129! , why?
void kalman(int a);
int main(void) { volatile signed int *rega = (volatile signed int *) 0x59000000; static int b; b =9; *rega=5; kalman(b);
}
void kalman(int a){
volatile signed int *rega = (volatile signed int *) 0x59000004; *rega=a;
Stop starting new threads about the same topic.
Clue: Some upstream code is not performing the initialization that the downstream code is predicated upon.
Find someone with a CS degree that took an "assemblers, compilers, linkers and loaders" type course, and understood it.
