Update: Sorry this is my first time posting. This the error I am getting in mbed
Fatal error: A1023E: File "../../build/mul_asm.NUCLEO_F401RE.E" could not be opened: No such file or directory 1 Error, 0 Warnings
from this block of code:
int perf_op(void)
{
unsigned char key;
int num1, num2, result;
key = keypad_scan();
if(key == 'A')
result = add_asm(num1, num2);
else if( key == 'B')
result = sub_asm(num1,num2);
else if(key == 'C')
result = mul_asm(num1,num2);
else if(key == 'D')
result = sdiv_asm(num1,num2);
else
return 0xFF;
return result;
}
It seems like it can't find the file in the directory, but it is in there and I have tripled checked the spelling and everything matches. Just wondering what other things could cause this error?
