Hello

I would like to use gpio group PJ.xx and check the document from pinmux_configuration_template which indicates

this group is 3.3v capable.

My question is how to define it’s 1.8v or 3.3v output? or could be 3.3v input into these pin when 1.8v has been configured.

hello john.chen,

please have pinmux customization, you may update the “IO Block Voltage” column for configurations.
please also refer to documentation, Jetson AGX Xavier MB1 Platform Configuration for pinmux configuration.
thanks
