[Error][JP 7.2.1] Errors during manual setup of basic samplefs

Hi, I get some errors when I’m setting generating the basic samplefs when I use apply_binaries.sh:

dpkg: dependency problems prevent configuration of nvidia-l4t-camera:
nvidia-l4t-camera depends on libc6-arm64-cross; however:
Package libc6-arm64-cross is not installed.

dpkg: dependency problems prevent configuration of nvidia-l4t-power-adapter-check:
nvidia-l4t-power-adapter-check depends on i2c-tools; however:
Package i2c-tools is not installed.

dpkg: dependency problems prevent configuration of nvidia-l4t-bsp:
nvidia-l4t-bsp depends on nvidia-l4t-camera (>> 39.2-0); however:
Package nvidia-l4t-camera is not configured yet.
nvidia-l4t-bsp depends on nvidia-l4t-camera (<< 39.3-0); however:
Package nvidia-l4t-camera is not configured yet.
nvidia-l4t-bsp depends on nvidia-l4t-power-adapter-check (>> 39.2-0); however:
Package nvidia-l4t-power-adapter-check is not configured yet.
nvidia-l4t-bsp depends on nvidia-l4t-power-adapter-check (<< 39.3-0); however:
Package nvidia-l4t-power-adapter-check is not configured yet.

  • From what I can see i2c-tools and libc6-arm64-cross are only included in the minimal and desktop package lists, so they should probably also be in basic too.

  • Also apply_binaries.sh leaves all the packages inside the rootfs, it should probably delete them after installation, 365MB can be significant.

Hi,

We confirmed that libc6-arm64-cross and i2c-tools are missing from the basic samplefs package list. We’ll validate the fix internally and update this thread with the solution once verification is complete.

Thank you for reporting this.

Hi,

We verified that adding libc6-arm64-cross and i2c-tools to the basic samplefs package list resolves the reported dependency errors on JetPack 7.2.1 / Jetson Linux R39.2.1. Please follow these steps:

  1. Prepare a fresh BSP working directory

    Extract the R39.2.1 BSP into a separate directory. Use an Ubuntu 24.04 build environment and leave the new Linux_for_Tegra/rootfs/ directory empty until step 4.

    Start in the new BSP directory, replacing the path below with your actual path:

    cd /path/to/fresh/Linux_for_Tegra

  2. Add the missing dependencies

    Edit tools/samplefs/nvubuntu-noble-basic-aarch64-packages and add these entries, one per line, while keeping the existing entries:

    libc6-arm64-cross
i2c-tools

  3. Regenerate the basic samplefs

    cd tools/samplefs
sudo ./nv_build_samplefs.sh --abi aarch64 --distro ubuntu --flavor basic --version noble
echo "samplefs exit status: $?"

    Continue only if the exit status is 0 and the script reports that a new sample_fs.tbz2 was generated.

  4. Extract the new rootfs and install the BSP packages

    cd ../..
sudo tar -xpf tools/samplefs/sample_fs.tbz2 -C rootfs

    After extraction completes successfully, run:

    sudo ./apply_binaries.sh
echo "apply_binaries exit status: $?"

    The expected result is Success! and exit status 0.

  5. Verify the packages and cleanup

    From the same Linux_for_Tegra/ directory, run:

    dpkg-query --admindir="$PWD/rootfs/var/lib/dpkg" -W -f='${binary:Package}: ${Status}\n' \
  libc6-arm64-cross i2c-tools nvidia-l4t-camera \
  nvidia-l4t-power-adapter-check nvidia-l4t-bsp
test ! -e rootfs/opt/nvidia/l4t-packages
echo "staging cleanup check: $?"

    All five packages should show install ok installed, and the cleanup check should return 0. In our successful test, the installer automatically removed the staged packages; no manual deletion was needed.

Recommendation: Use the freshly generated rootfs for this validation so the previous failed installation does not affect the result. Please confirm whether these steps resolve the issue on your setup.

Thanks.
