Creating Backup of TX1 with tegraflash.py fails

Autonomous Machines Jetson & Embedded Systems Jetson TX1
1

Hello,

I am trying to create a full system Backup of the TX1 with the tegraflash.py script in the bootloader directory of the Jetson Software on my Host PC.

Inside the script I get the error [ 1.0613 ] 00000004: Failed to get an accessor of secondary boot device

I execute the following command:

sudo ./tegraflash.py --bl cboot.bin --applet nvtboot_recovery.bin --chip 0x21 --cmd "read APP my_backup_image_APP.img"

I get the following output:

~/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P2180/Linux_for_Tegra/bootloader$ sudo ./tegraflash.py --bl cboot.bin --applet nvtboot_recovery.bin --chip 0x21 --cmd "read APP my_backup_image_APP.img"

hello Michael,

could you please use the flash script to perform the image backup process.
for example,

Usage: sudo ./flash.sh [options] <target_board> <rootdev>
  Where,
	target board: Valid target board name.
	rootdev: Proper root device.
    options:
        ...
        -G <file name> ------- Read partition and save image to file.

suggest you could also check similar discussion thread, Topic 1058035.
you might also check the Flashing and Booting the Target Device chapter for reference,
thanks
