We have developed custom carrier board based for Jetson AGX ORIN(32GB). In that, Some of the GPIO pins can be configured only as ‘Output’ direction not as Input/Bidirectional.
In pinmux sheet, If I changed pin direction from ‘Output’ to ‘Bidirectional/Input’, it shows an error “GPIO3_PR.02 Should not be set as Bidirectional/input”. So, I have manually changed the pinmux in the dtsi file as below.
i configured these gpio as input and loopback with another output gpio (set output value as high). if i read the input gpio value , it always show as LOW.
Yes, I’m using v1.8 of Jetson_AGX_Orin_Series_Pinmux_Config_Template.xlsm.
I can configure PR.02 as ‘bidirectional’ by using spreadsheet but it was not working as input. Even, other GPIO’s (PH.03, PH.05, PY.05 and PY.07) can’t be configure as bi-directional in Spreadsheet as well as dtb(The changes was not reflected) .
