Hi WayneWWW:
I edit Orin_Jetson_Series_Pinmux_Config_Template.xlsm file ,chage GPIO08 output

1. generate three dtsi files
2. replace those 3 files
   [egra234-mb1-bct-pinmux-p3701-0000.dtsi
   tegra234-mb1-bct-gpio-p3701-0000.dtsi
   tegra234-mb1-bct-padvoltage-p3701-0000-a04.dtsi ] Linux_for_Tegra/bootloader/t186ref/BCT and Linux_for_Tegra/bootloader/
   3…/flash.sh -r jetson-agx-orin-devkit mmcblk0p1
   reboot
   then
   cd /sys/class/gpio/
   echo 325 >export
   cd PBB.01
   echo out > direction
   echo 1 > value
