Hello everyone,
I’m using Jetpack 5.0.2
/ L4T R 35.1
and I’m building OPTEE
(OS , Client , Samples and Test ) from sources Linux_for_Tegra/source/public/nvidia-jetson-optee-source.tbz2
I’m using GCC version 12.2.0 . When running the xtest
(OPTEE test suite), I noticed the CPU hangs for a moment then system reboot
Kindly see the logs below:
��[ 368.162281] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

Any idea about the cause of the CPU hanging ?
Any help would be appreciated.
Best regards,
Ilies

The updated toolchain has been posted in Jetson downloads page, please help to get it a try. Thanks
Could you please share the link ? if I’m not mistaken, it is still Bootlin Toolchain gcc 9.3 . It is not updated FYI.
As I mentioned in this topic help is needed for toolchain which is using gcc-12.x.y
and bintutils 2.39
Did you apply any patches to the OPTEE sources ? if so, please share the pachtes and I can try them
Thanks for you help

Hello @DaneLLL @kayccc @ShaneCCC
I think that you didn’t understand my request here.
I tried the toolchain you provide and it works fine. My issue is related to new toolchain and this is a blocker for us (OE4T community ) to moving forward.
My PR is still pending because of the issue I shared with you in this topic.
Could you please try with this toolchain ?
Any help from your side would much appreciated

Hi,
Are you able to use the toolchain we provide? It is the version we use and would suggest forum users use the same version.
Hello @DaneLLL
I was able to try the toolchain you provide and it works fine.
FYI, we have fixed the issue in our meta-tegra layer. Many thanks to @madisox
