Memory Conflicts in onchip ram

Hi,

There's some mistake in the previous code posted. Done modified as below:

int main() {

int i = 262144;

unsigned int addr;

unsigned int result;

for (addr = BASE_ADDRESS; addr <= 0x40019; addr+=4) {

IOWR_32DIRECT(addr, 0x4, i);

i++;

}

for (result = BASE_ADDRESS; result <= 0x40019; result++ ) {

printf("Address: 0x%x, Value: %d\n", result, IORD_32DIRECT(result, 0x4));

}

printf("Address: 0x40016, Value: %d\n", IORD_32DIRECT(0x40016, 0x4));

printf("Address: 0x40007, Value: %d\n", IORD_32DIRECT(0x40007, 0x4));

return 0;

}

Terminal screenshot below:

Address part is increasing correctly and can read value outside the loop correctly. Ya, you're right can pass directly the numerical value.

You can checkout this link https://fys4220.github.io/part-exercises/exercises_memory_mapped_sw.html on byte-oriented offset for IOWR_32DIRECT and IORD_32DIRECT

Thanks,

Best Regards,
