Creating Linux Root Filesystem in NVIDIA DriveOS 7.0#
To reduce the space consumed by platform-specific Linux Root Filesystems (RFS) in the NVIDIA DriveOS™ SDK Docker Image, only the Linux pre-rfs tarballs are present in the SDK. This pre-rfs contains files common for all supported platforms.
Use one of the following methods to generate the final flashable RFS by adding platform-specific files and other NVIDIA files to the pre-rfs.
Option 1: Using bind_partitions#
If a Linux Root Filesystem does not exist on the host, bind_partitions automatically creates an RFS for the appropriate platform in the /drive/drive-linux/filesystem/targetfs-images directory. This is supported for prod_nsr, test_nsr, and dev_nsr PCT variants.
Option 2: Using create_linux_targetfs.sh#
Manually execute the following command to create a flashable Linux RFS in the /drive/drive-linux/filesystem/targetfs-images directory.
/drive/drive-linux/filesystem/create_linux_targetfs.sh -t <target_platform> -p <pct_variant>
