Linux for tegra


I’m trying to build optee for jetson xavier NX. Extracted the public_sources/Linux_for_Tegra/source/public/atf_src.tbz2 of the bsp source ,there I found readme file and followed the steps given in it . I’m not able to find in the release 35.5.0. but in 32.6.1 it is in the directory Linux_for_tegra/nv_tegra/ . Can anyone help me in this.


Welcome to the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.


hello sushmitha.sp,

it’s now (i.e. release-35) to use op-tee, please extract atf_src.tbz2 and nvidia-jetson-optee-source.tbz2 to the same folder, and checking atf_and_optee_README.txt for the instructions.


I have followed the readme but I couldn’t find the file Only source folder is there in Linux_for_tegra directory in the 35.5.0 release but in previous release nv_tegra folder is there in Linux_for_tegra directory.

hello sushmitha.sp,

did you download/install JetPack-5.1.3 public release to your local host?
it should be available as following…

Hi Jerry,

I installed the source from here Jetson Linux | NVIDIA Developer and I followed atf_and_optee_README.txt file and I have built the sdk.

Now I want to generate image but I couldn’t find in the path you specified public_sources/Linux_for_Tegra/

you have to download Jetpack SDK, please check SDK Manager | NVIDIA Developer.
