Make Jetson Xavier AGX GPIO low

Hi I want to make GPIO20 to be set as LOW, where All I need to change if I am building the kernel/BSP from sources using tegra_defconfig? I know I need to change in pinmux config file to make it to drive 0. what else in which all files I need to make change?

hello venkatraman.bhat,

here’s Jetson-IO python tool to simplify the configuration of the I/Os exposed by the 40‑pin expansion header.
please check developer guide for reference, Configuring the 40-Pin Expansion Header.
