How to use GPIO05_PP5 in xavier AGX

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 :

  1. cd /sys/class/gpio
  2. export 491 > export
  3. echo in > direction
  4. cat value

But I don’t know the num for GPIO04_PP4, and so do for GPIO05_PP5, GPIO06_PP6.

…??? Just 490 and 492.

thanks for your reply!
but there are 3 pin here(GPIO04_PP4, GPIO05_PP5 and GPIO06_PP6 ), Can you tell me all the num again？

#5

You probably take it wrong… Only GPIOx_PP4,GPIOx_PP5,GPIOx_PP6. The x is the same number…

#6

yes, these 3 pin name are GPIO3_PP4, GPIO3_PP5 and GPIO3_PP6

#7

hi, wayneWWW，as you said，the x is 3, and how can I get the num of these GPIO pin?
looking forward to your reply.
