Need GPIO

Hi
I need 4 GPIOs. In 40Pin Header (J21), I’m using all i2c, uart and i2s peripherals.
Which pins and how can I use as GPIO. The GPIOs I need do not have to be in the header, anywhere and connected to any connector

hello nimadibaj,

you may refer to https://github.com/NVIDIA/jetson-gpio to enables the use of Jetson’s GPIOs.
thanks
