Please to help to provide the sop how to configure gpio(40pin GPIO01 and GPIO_12) as open drain?
I had tried to used pinmux excel and turn it to dtsi, and used the dts2cfg.py to turn it to tegra19x-mb1-pinmux-p3668-a01.cfg
But it looks no working, it is still default value
please share your steps for update pinmux cfg, did you use full flash to flash the target?
tegra19x-mb1-pinmux-p3668-a01.cfg (27.2 KB)
Please ref the attached file for config file, and yes we reflash device by sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1
An open-drain pin needs external pull-up. On devkit, the pins you used can not be set as OD as there is no such pull-up on board.
