With regards to Jetson nano carrier board AUVidea JN30B GPIOs . In the technical reference page 13, there is J22 where we have (SPI2_SCK,SPI2_MISO,etc)
Those pins are not defined in the /sys/kernel/debug/GPIO
And so I could not activate any of them to turn a relay on and off.
Can you please advise how to interact with those GPIOs , if there is a need for kernel/device tree update would you please provide that
