Hi All, trying to write a very simple program to access GPIO pins from C source; Monitor Program works great (NIOS II cpu), but want to run on the DE1 Board itself. Need a listing of GPIO-related addresses for test

Hi YL,
thank you very much! I stumbled onto a partial answer (the booted Linux OS does not have direct access to the GPIO hardware (40-pin) like the user leds do). Instead, the 40pin is directly connected to FPGA
