To resolve the rootfs AB issue on your Jetson Orin Nano, you need to reflash the board. Here’s a step-by-step guide to help you through the process:
Step 1: Determine the type of your Jetson module
To determine the type of your Jetson module, you need to check the output of the lsusb command. Open a terminal window on your host computer and enter the command lsusb. Look for the message that indicates the type of your Jetson module. In your case, since you have a Jetson Orin Nano, the output should show 0955:7523 or 0955:7623, which corresponds to the Jetson Orin Nano (P3767-0003 and P3767-0005 with 8GB) or Jetson Orin Nano (P3767-0004 with 4GB), respectively.
Step 2: Prepare the flashing environment
To flash your Jetson Orin Nano, you need to prepare the flashing environment. Make sure you have the following:
- A Linux host computer
- A USB cable to connect your Jetson Orin Nano to the host computer
- The
Linux_for_Tegra directory, which contains the flashing tools and scripts
- The
nv-oem-config setup files, which are included in the apply_binaries.sh script
Step 3: Flash the Jetson Orin Nano
To flash your Jetson Orin Nano, follow these steps:
- Connect your Jetson Orin Nano to the host computer using a USB cable.
- Open a terminal window on the host computer and navigate to the
Linux_for_Tegra directory.
- Run the following command to flash the Jetson Orin Nano:
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -u <pkc_keyfile> [-v <sbk_keyfile>] --uefi-keys uefi_keys/uefi_keys.conf -p “-c ./bootloader/generic/cfg/flash_t234_qspi.xml” -c ./tools/kernel_flash/flash_l4t_t234_nvme.xml --showlogs --network usb0 jetson-orin-nano-devkit external
Replace `<pkc_keyfile>` and `<sbk_keyfile>` with the actual file paths to your PKC and SBK key files, respectively.
**Step 4: Apply the nv-oem-config setup files**
After flashing the Jetson Orin Nano, you need to apply the `nv-oem-config` setup files. Run the following command:
```bash
sudo ./apply_binaries.sh -r <root>
Replace <root> with the actual mount point of the backup.img.raw file.
Step 5: Set the default target
To set the default target, run the following commands:
cd $root/etc/systemd/system
sudo rm default.target
sudo ln -s /lib/systemd/system/nv-oem-config.target default.target
Replace <root> with the actual mount point of the backup.img.raw file.
Step 6: Unmount the device
After setting the default target, unmount the device:
umount $root
Replace <root> with the actual mount point of the backup.img.raw file.
Step 7: Create a sparse version of the updated image file
To create a sparse version of the updated image file, run the following command:
sudo ./mksparse -v –fillpattern=0 /path/to/backup.img.raw system.img
Replace /path/to/backup.img.raw with the actual file path to the backup.img.raw file.
Step 8: Flash the system.img file
Finally, flash the system.img file to the target device. For details, see the documentation on cloning a Jetson device and flashing.
By following these steps, you should be able to resolve the rootfs AB issue on your Jetson Orin Nano and get your device up and running again.
