I want to control the pin 8 and pin 10 and pin 11 of the BCM code. I want to know which gpiochip is under /sys/class/gpio/?

i find in jetson-gpio\lib\python\Jetson\GPIO

BCM = 10
BOARD PING =19
But 16 does not seem to be /sys/class/gpio/ encoding, I found no response with the meter test

hello hnwangkg,

suppose you would like to control J41 pinout,
please check NVIDIA Jetson Nano J41 Header Pinout for the reference.

you may also check Topic 1030443 and Topic 1001584 for more details.
thanks
