Bug With Status LED on NX Dev Kit

Hi,

I found a bug that is somewhate strange. the Status LED, which is accessible on via J14 does not work correctly.

The LED does not turn off when I run the command: sudo systemctl suspend However according to the datasheet of the dev kit carrier board, it should turn off when the NX is in sleep mode.

Any ideas how I can solve this issue?

hello alexisguiter,

may I know which JetPack release version you’re working with?
could you please also check Xavier NX’s device tree, do you have suspend_gpio: suspend-led-gpio{} definition included.
thanks

Hi,

Where and how can I check the device tree?

hello alexisguiter,

you may disassembler the dtb file into text file for quick checks.
for example, $ dtc -I dtb -O dts -o output.dts tegra194-p3668-all-p3509-0000.dtb

or, you may access L4T Driver Package (BSP) Sources and check source code for Xavier NX’s device tree.
for example,
$L4T_Sources/r32.5/Linux_for_Tegra/source/public/hardware/nvidia/platform/t19x/jakku/*
