Backup and Restore FLYC-300

Prerequisites

• Prepare a host computer with corresponding JetPack version environment and have the L4T created [ref]

• Download the corresponding JetPack tarball (e.g., flyc300_2024-01-22_1911.tar.gz ) from NRU NAS

This method is most stable with the identical NVMe storage model.

Otherwise, we would recommend our customers to use a physical M.2 duplicator for NVMe backup.

Backup

• Put FLYC-300 into recovery mode [ref]

• Connect FLYC-300 with the host computer by a USB Type C to Type A cable

• Enter the following command on the host computer

cd $L4T
sudo ./tools/backup_restore_nvme/l4t_backup_restore.sh -b flyc300

# Pack nvme system image as a tarball
# sudo tar cvf images.tar ./tools/backup_restore_nvme/images/

Restore

For a fresh new Jetson module or NVMe, please flash them with pinmux once by cd $L4T sudo ./flash_flyc300_dtb+pinmux.sh

• Put FLYC-300 into recovery mode [ref]

• Connect FLYC-300 with the host computer by a USB Type C to Type A cable

• Assure you have prepared the BSP from

  • The backup steps [ref]

  • Or, download the pre-packed BSP from NRU NAS [link]

• Enter the following command on the host computer

cd $L4T
sudo ./tools/backup_restore_nvme/l4t_backup_restore.sh -r flyc300

Restoring failed with Error Message

The above error message implies that the host computer failed to find the FLYC-300 on the USB bus. You may manually to make the following change to force the host computer to use usb0 to flash.

Leveraging the Pre-packed BSP

Content of Pre-packed BSP

• Jetson SDK, e.g., CUDA, DeepStream, TensorRT, etc ...

• acpid for power button [ref]

• GMSL2 camera driver for selected GMSL2 cameras, e.g., AC-IMX390, AC-IMX490, AC-AR0233

Download the Pre-packed BSP

• Download the pre-packed FLYC-300 BSP from NRU NAS

• Put the images.tar into L4T folder

• Enter the following command on the host computer

sudo tar xvf images.tar
