RAS Driver for Hardware Fault Detection in Jetpack 6.1

Hello,

I’m working on a project involving a Jetson Orin NX (16GB) running Jetpack 6.1, focused on finding hardware faults and exploring fault injection to test the RAS (Reliability, Availability, and Serviceability) capabilities. I noticed that the RAS driver moved from the kernel to ATF.

If possible, I would like to know if there’s a way to output RAS messages through dmesg and inject fault through software so that I can test this RAS? Any documentations on how to build and run ATF would be helpful too.

Thanks.

Hi,
The ATF source code is in

Jetson Linux | NVIDIA Developer
Driver Package (BSP) Sources

Please download it and follow README to build it.

Thanks for the link. However, may I know if RAS driver has already been built in by default when flashing Jetpack with SDK Manager so we can just observe errors through UART?

Hi,
Looks like it is not enabled by default. Please enable it in

arm-trusted-firmware/make_helpers/defaults.mk

And follow README to rebuild/reflash the image.
