This works for me on mica2:
void func()
{
uint8_t key1[10] = "1234543253"; uint8_t key2[10] = "1234543323";
int i ;
uint8_t result[10];
for(i = 0; i < 10; i++)
result[i] = key1[i] ^ key2[i];
}
You did name key1,2 differently (k1, k2) in your code snippet
but that should have given a syntax error....
Better start looking someplace else for the actual problem.
