OpenEmbedded/Yocto BSP layer for NVIDIA Tegra X1/X2/AGX/K1 ========================================================== Boards supported: * Jetson-TK1 development kit (Linux4Tegra R21.7) * Jetson-TX1 development kit (Linux4Tegra R32.2.1, JetPack 4.2.2 * Jetson-TX2 development kit (Linux4Tegra R32.2.1, JetPack 4.2.2) * Jetson AGX Xavier development kit (Linux4Tegra R32.2, JetPack 4.2.2) * Jetson Nano development kit (Linux4Tegra R32.2.1, JetPack 4.2.2) Also supported: * Jetson-TX2i module (Linux4Tegra R32.2.1, JetPack 4.2.2) This layer depends on: URI: git://git.openembedded.org/openembedded-core branch: master LAYERSERIES_COMPAT: warrior PLEASE NOTE ----------- * Starting with JetPack 4.2, packages outside the L4T BSP can only be downloaded with an NVIDIA Developer Network login. So to use CUDA 10, cuDNN, and any other 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. * 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. * The tensorrt 5.1.6 packages for Xavier are different from those for TX1/TX2, even though the deb files have the same name. If you need to build for Xavier and another platform and include tensorrt 5.1.6, create a subdirectory called "P2888" under your NVIDIA_DEVNET_MIRROR directory, and copy the Xavier tensorrt packages there. The non-Xavier copies should go in the NVIDIA_DEVNET_MIRROR top level. * CUDA 10 supports up through gcc 7 only, and some NVIDIA-provided binary libraries appear to be compiled with g++ 7 and cause linker failures when building applications with g++ 6, so **only** gcc 7 should be used if you intend to use CUDA. (For Jetson-TK1, CUDA 6.5 supports up through gcc 5.x only.) Selecting the toolchain version ------------------------------- Toolchain version selection is usually a distro configuration setting, but you can also set this in your build/conf/local.conf file. To use gcc 7 instead of gcc 8, set: GCCVERSION = "7.%" but you will also need the gcc 7 toolchain recipes in one of your layers, since it was retired from OE-Core in favor of gcc 8.
