Jetson Linux 36.2 JetPack 6.0 – Custom Image Creation Issues

Issue Overview

Users are experiencing difficulties when attempting to create a custom image for the Nvidia Jetson Orin Nano Dev board using the latest Jetson Linux 36.2 JetPack 6.0. The primary issue occurs when running the jetson-disk-image-creator.sh script, which is designed to generate a customized image for flashing onto an SD card. Users encounter various errors during the process, including missing files, unmet dependencies, and configuration problems.

The issue appears to be more prevalent when users are attempting to build their own rootfs using a Docker approach, rather than using the default rootfs provided by NVIDIA. This custom rootfs creation seems to be missing several crucial packages and binaries required for successful image creation.

Possible Causes

1. Incomplete rootfs: The custom rootfs created using Docker may be missing essential packages and binaries required for the Jetson platform.

2. Dependency issues: Several packages have unmet dependencies, preventing proper installation and configuration.

3. Missing system files: Critical system files such as busybox, sfdisk, and various libraries are not present in the expected locations.

4. Incompatible or outdated packages: Some packages may not be compatible with the latest JetPack 6.0 release or may be outdated.

5. Incorrect file permissions: Certain files or directories may have incorrect permissions, preventing the script from accessing or modifying them.

6. Environment configuration: The build environment may not be properly set up, leading to issues with file paths or system variables.

Troubleshooting Steps, Solutions & Fixes

1. Use NVIDIA’s default rootfs:

   • If possible, start with NVIDIA’s default rootfs and customize from there.
   • Download the BSP package from NVIDIA SDK Manager (SDKM) and use it as a base for customization.

2. Add missing packages:

   • Identify the missing packages from the error messages and add them to your custom rootfs.
   • Key packages to include:

     busybox
     util-linux (for sfdisk)
     gdisk (for sgdisk)
     libwrap0
     libmnl0
     libfdisk1
     openssh-server
     iputils-ping
     isc-dhcp-client
     iproute2
     xxd
     

3. Resolve dependency issues:

   • Install the following packages and their dependencies:

     libegl1-mesa
     bridge-utils
     device-tree-compiler
     gir1.2-appindicator3-0.1
     libffi7
     

4. Run apply_binaries.sh:

   • Execute sudo ./apply_binaries.sh before running jetson-disk-image-creator.sh.
   • This script applies necessary binaries to the rootfs.

5. Check file permissions:

   • Ensure that all files and directories have the correct permissions.
   • Run chmod and chown commands as necessary.

6. Verify kernel image:

   • Check if /tmp/jetson-builder/build/Linux_for_Tegra/kernel/Image exists and is in the correct format.
   • If missing or corrupted, rebuild or reacquire the kernel image.

7. Update Dockerfile:

   • Modify your Dockerfile to include all necessary packages and dependencies.
   • Example additions:

     RUN apt-get update && apt-get install -y \
         busybox \
         util-linux \
         gdisk \
         libwrap0 \
         libmnl0 \
         libfdisk1 \
         openssh-server \
         iputils-ping \
         isc-dhcp-client \
         iproute2 \
         vim-common \
         libegl1-mesa \
         bridge-utils \
         device-tree-compiler \
         gir1.2-appindicator3-0.1 \
         libffi7
     

8. Check system paths:

   • Verify that all required files are in the correct locations within your custom rootfs.
   • Adjust file paths in scripts if necessary.

9. Use NVIDIA forums and documentation:

   • Consult NVIDIA’s official documentation for JetPack 6.0 and Jetson Orin Nano.
   • Seek assistance on NVIDIA Developer forums for specific issues.

10. Consider using SDKM for flashing:

    • If custom image creation proves too challenging, consider using NVIDIA SDK Manager for flashing the initial image and then customize post-installation.

By following these steps and ensuring all necessary components are present in your custom rootfs, you should be able to resolve the issues with creating a custom image for the Nvidia Jetson Orin Nano Dev board using Jetson Linux 36.2 JetPack 6.0.
