NVIDIA recommends using L4T R32.3.1/JetPack 4.3 for production use. The JetPack release supported here is labeled a "developer preview".
-
Some packages outside the L4T BSP can only be downloaded with an NVIDIA Developer Network login - in particular, the CUDA host-side tools.
To use any packages that require a Devnet login, you must create a Devnet account and download the JetPack packages you need for your builds using NVIDIA SDK Manager.
You must then set the variable NVIDIA_DEVNET_MIRROR to "file://path/to/the/downloads" in your build configuration (e.g., local.conf) to make them available to your bitbake builds. This can be the NVIDIA SDK Manager downloads directory,
/home/$USER/Downloads/nvidia/sdkm_downloads -
The SDK Manager downloads a different package of CUDA host-side tools depending on whether you are running Ubuntu 16.04 or 18.04. If you downloaded the Ubuntu 16.04 package, you should add
CUDA_BINARIES_NATIVE = "cuda-binaries-ubuntu1604-native"to your build configuration so the CUDA recipes can find them. Otherwise, the recipes will default to looking for the Ubuntu 18.04 package.
-
CUDA 10.2 supports up through gcc 8 only. Pre-built binaries in the BSP appear to be compatible with gcc 7 and 8 only. So use only gcc 7 or gcc 8 if you intend to use CUDA. Recipes for gcc 8 have been imported from the OE-Core warrior branch (the last version of OE-Core to supply gcc 8) to make it easier to use this older toolchain.
See this wiki page for information on adding the
meta-tegra/contriblayer to your builds and configuring them for GCC 8.
