Hello everyone

I have a jetson nano production module.
I want to set it to “Suspend Mode” with the command

sudo systemctl suspend

However when i enter that command the following output is genereate ( from the debug console) :

nvidia@admin:~$ sudo systemctl suspend
nvidia@admin:~$ [  376.042018] tegra_cec 70015000.tegra_cec: suspended
[  377.474049] PM: noirq suspend of devices failed
[  377.498654] tegra_cec 70015000.tegra_cec: Resuming
[  377.504032] tegra_cec 70015000.tegra_cec: tegra_cec_init started
[  378.512883] tegra_cec 70015000.tegra_cec: tegra_cec_init Done.

Additional info:

nvidia@admin:~$ cat /sys/power/state
freeze mem

nvidia@admin:~$ cat /etc/nv_tegra_release
# R32 (release), REVISION: 6.1, GCID: 27863751, BOARD: t210ref, EABI: aarch64, DATE: Mon Jul 26 19:20:30 UTC 2021

Any help, idea, tipps would be appreciated.

Best regards and thank you in advance.

Sorry for the late respond, had holidays.

cat /proc/device-tree/nvidia,dtsfilename
arch/arm64/boot/dts/../../../../../../hardware/nvidia/platform/t210/porg/kernel-dts/tegra210-p3448-0002-p3449-0000-b00.dts

So B01.
