How to enable PMIC WDT on Orin DevKits


I’m trying to use the built in Watchdog features of the Jetson AGX Orin DevKit.
Is there a PMIC WDT like in the previous versions and how do i enable it?
I can’t find files containing ODMDATA like in the TX2 for example.

Best Regards

  1. Set the option CONFIG_RTC_HCTOSYS_DEVICE as rtc0 in tegra_defconfig
  2. Modify the /lib/udev/rules.d/50-udev-default.rules to below for the problem.
SUBSYSTEM=="rtc", ATTR{hctosys}=="0", SYMLINK+="rtc"
SUBSYSTEM=="rtc", KERNEL=="rtc0", SYMLINK+="rtc", OPTIONS+="link_priority=-100"

Hi ShaneCCC,

thanks for the reply!
I’m trying to locate tegra_defconfig.
The File can’t be found in the installation sources.

I also tried following this post:

I’m using Jetpack 5.0.3 (Rev 1)


it seems [...]/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegralike/ is broken

Directory for kernel/kernel-5.10, /home/khacker/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra/sources/kernel/kernel-5.10, already exists!
Please enter a tag to sync /home/khacker/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra/sources/kernel/kernel-5.10 source to
(enter nothing to skip):

I found the file downloading sources manually here

Update 2:

found the missing Tag to be jetson_35.1 in release notes

Please download the Driver Package (BSP) Sources for J5.0.2
