Sorry for the noob question. I tried to find a toolchain for Orange Pi 3 and couldn't. The sources would also help me, I'm going to work with GPIO from C++. Sunxi tools are not suitable for this board and Armbian. The program cannot be run on Armbian and gdbserver reports that it does not know how to run it. How to write programs for Armbian and orange Pi 3 in C/C++?
