hi, we designed xarier AGX bottom board, now I should use GPIO05_PP5 pin to detect external voltage signal, but there is some trouble while I get the number for GPIO05_PP5.
I get some step from internet about how I can use GPIO :
- cd /sys/class/gpio
- export 491 > export
- echo in > direction
- cat value
But I don’t know the num for GPIO04_PP4, and so do for GPIO05_PP5, GPIO06_PP6.
