→‎Compile and run program

Constants GPIO1 and GPIO2: they configure GPIOs used for debug via oscilloscope. By default, 158 and 162 values are not used in IGEPv2. Configure [[Mux configuration|mux]] properly if you use other GPIOs.

Compile program source code using your Cross Compiler, I used arm-linux-gnueabi-a [[How to setup a cross compiler|cross compiler]] for example IGEP SDK: <pre>arm-poky-linux-gnueabi-gcc uart-test-2-beta1.c -o uart-test-beta1 </pre>
