Backup restore, workflow #3 massflash jetson orin nano problem

Hello everyone,

I have custom carrier board which trying to mass clone, restore to one device are working fine, but with 500+ will be hell, so I trying to use workflow #3 from initrd README

First step make a backup from prepared device, success

./tools/backup_restore/l4t_backup_restore.sh -b -c p3509-a02+p3767-0000

Seconds step, create package for mass flashing, in guide last argument are mmcblk0p1 but I have only nvme inside so I replace it with nvme0n1, success

./tools/kernel_flash/l4t_initrd_flash.sh --use-backup-image --no-flash --network usb0 --massflash 10 p3509-a02+p3767-0000

Third step, crashed after device rebooted for SSH commands, I dont fully understand why its trying to create GPT for emmc, which I dont have one, tried even manually removed it from scripts ( there was horrible things will happen if I do this ) failed

Attempts to add external device param dont do anything

./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 10 --network usb0

Another variation of command and output

./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 2 --network usb0 --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_external.xml p3509-a02+p3767-0000 nvme0n1p1

Nothing works, still the same error

Hi,

I don’t believe this would succeed. Are you sure you have stuff like nvme0n1p<x>.img populated?
Please replace every instance of mmcblk0 with nvme0n1 in nvbackup_partitions.sh and nvrestore_partitions.sh and generate the image again.

Also, the function of converting backup image from external devices to massflash image does not work with the current setup.
It’s guaranteed to fail as of now.
Please apply this patch:

Hi Dave,

Thank you for quick answer, my bad as I forgot to mention, this was already done

Please replace every instance of mmcblk0 with nvme0n1 in nvbackup_partitions.sh and nvrestore_partitions.sh and generate the image again.

Backup and restore to one device are working

I applied patch manually instead of git apply as it said patch are corrupted, and last bracket should not be deleted probably

After command ./tools/backup_restore/l4t_backup_restore.sh -b -c p3509-a02+p3767-0000
I get output was backup was done successfully but while conversion to initrd image popup error

gzip nvme0n1p1.tar.gz not found

I checked the folders Linux_for_Tegra/tools/backup_restore/images# ls -lah

File are there, all seems correct and file was inside Linux_for_Tegra/tools/kernel_flash/images/external

I still tried to proceed to creating package via command

Package seems created and tar file are there, but look like its corrupted

  1. Is there any chance you can send me archived tools directly with patched scripts?
  2. Can I start conversion from backup without making backup from device each time?
  3. Also is it possible just run restore commands in sequence when last device started in initrd mode for ssh restore? As I have big problems with converting image maybe there is second way?

This is the full script.
I built this patch on top of 35.4.1, and I’m sure it’s working fine on 35.4.1.
I didn’t verify on 35.3.1, so maybe there are something different between these two versions leading to the error.

Sure. Just run the l4t_backup_restore.func script directly.
You need some trick to set the folder path and move the code out of the function block.

I don’t see why you cannot.

Hi,

I verified on 35.3.1 again with the full script I posted earlier, and it was working fine.
Please give it a try.

Hi Dave,

I used your complete file and it seems start working
Thank you very much for help, I will proceed testing

Good morning Dave,

I have additional questions, if you can answer, I will be very grateful

When I am flashing multiple devices at the same time, seems like speed divided by numbers of devices, I made small research, for fix that we need:

  • usb hub with external power

Also seems like OTG socket in jetson are USB-2.0

Question 1: do we need special usb hub 2.0 with multi tt technology for improve USB-2.0 into semi USB-3.0?

Question 2: if we will use hub with USB-3.0 and external power ( which come without multi tt ) means our write speed will be limited to USB-2.0 but at least not divided when we are using regular usb hub from PC?
