To build CuDNN with tegra-drive-os-av-image

Note

Before building CuDNN with Yocto, you must install and enable CUDA on the host. For the supported CuDNN toolkit version, see product Release Notes.

Example to extract the CuDNN-toolkit-version version:

nvidia@dl20-0441:/drive$ ls /drive/drive-linux/toolkits/cudnn/cudnn* | sort

  /drive/drive-linux/toolkits/cudnn/cudnn-local-tegra-repo-ubuntu2404-9.7.1_1.0-1_arm64.deb

The CuDNN-toolkit-version is 9.7.1.

1. Export the CUDNN_ENABLE variable:

   export CUDNN_ENABLE=<CuDNN-toolkit-version>
   

2. Build or rebuild the image:

   bitbake tegra-drive-os-av-image
   

Note

The WARNING message “Unable to get checksum for cudnn-samples SRC_URI entry cudnnTest--ubuntu<>-aarch64-v.tgz: file could not be found” is expected when CUDNN_ENABLE is set.
