I’ve installed armbian on banana pi m7. I was trying to follow examples from Getting Started on 40-pin header about compiling Wiring for M7. I cloned and built the code as recommended. But when i try to run gpio readall, i get following error:
--
mds@bananapim7:~/wiring/wiring-armbian$ gpio readall
wiringPiSetup: mmap (PWM) failed: Operation not permitted
--
May be i miss something in the docs? Is there any other way to initialise an additional UART using GPIO pins from M7 to work with an external device over serial from armbian?
