Jetson agx orin clone and restore issue

[lpz_thread]

I use “sudo ./tools/backup_restore/l4t_backup_restore.sh -e mmcblk0 -b jetson-agx-orin-devkit” clone one orin, and then use “sudo ./tools/backup_restore/l4t_backup_restore.sh -e mmcblk0 -r jetson-agx-orin-devkit” restore it on another orin, but an error occurred during the recovery process:

“nvrestore_partitions.sh: You are trying to flash images from a board model that does not match the current board you’re flashing onto.”

I found the shell code in file tools/backup_restore/nvrestore_partitions.sh：

for value in $(grep -v -e '(^ *$|^#)' < "${FILE_NAME}"); do
  declare -a FIELDS
  for part in {1..6}; do
    FIELDS[part]=$(echo "$value" | awk -F, -v part=${part} '{print $part}')
  done
  if [ "${FIELDS[1]}" = 'board_spec' ]; then
    set_board_spec
    if [[ "${FIELDS[2]}" == "${BOARD_SPEC}" ]]; then
      BOARD_MATCH=true
    fi
  fi
done
if [ ${BOARD_MATCH} = false ]; then
  echo "${SCRIPT_NAME}: You are trying to flash images from a board model that does not"
  echo "match the current board you're flashing onto."
  exit 1
fi

I print “${FIELDS[2]}” and “${BOARD_SPEC}”, they do not match:

FIELDS[2]:3701-500-0005-R.0-1-1-jetson-agx-orin-devkit-, BOARD_SPEC:3701-501-0005-G.0-1-1-jetson-agx-orin-devkit-

Question:

1、So can I modify this code to make it force a match? Will there be any issues if I do so?
2、Sometimes, when cloning or restoring, there is no log prompt like “nvrestore_partitions.sh Restoring mmcblk0 with image mmcblk0pxx_bak.img”. And the orin device restored cannot be started normally. I’m not sure what the problem is in this situation, because there is no error prompt. Here is part of the log：

Hi,

@lpz_thread

1、So can I modify this code to make it force a match? Will there be any issues if I do so?

It’s fine to force a match.

2、Sometimes, when cloning or restoring, there is no log prompt like “nvrestore_partitions.sh Restoring mmcblk0 with image mmcblk0pxx_bak.img”. And the orin device restored cannot be started normally. I’m not sure what the problem is in this situation, because there is no error prompt. Here is part of the log：

What is your bsp version?

Thanks

we used jetson36.4.3，but it’s always failed when we restore on another orin:

Hi,

Please refer to the related issue:

AGX Orin 64GB (699-13701-0005-502) – Flash Failure Between L.0 and K.0 Board Revisions (L4T 35.6.0)

We use three types of eMMc for the BOM that have different sizes: - Micron 170-0547-900 Original eMMC: 63652757504 / 512 = 124321792 sectors - Sandisk 170-0637-300 Second eMMC: 63585648640 / 512 = 124190720 sectors - Kingston 170-0695-000 Third eMMC: 62625153024 / 512 = 122314752 sectors So the K.0 probably use a smaller eMMC size comparing to the L.0. I think you should perform a clean flash on K.0, create a production rootfs on the K.0, then create the backup image from …

Thanks

Hi，

We encountered another issue on one of our computers, which is not a virtual machine and runs Ubuntu 22.04. The cloning process consistently fails, and the running log ends with “tar: Write checkpoint 2990000”. Could you please advise on the possible causes of this problem and how we can avoid it ?

Hi,

It is a normal backup process.
Have you checked how much storage is available on the host?

Thanks

[lpz_thread]

yes，I checked there are over 300GB of free space remaining，I think it’s enough.

[DavidDDD]

Hi,

Some questions to confirm:
Is your host a virtual machine or a physical machine?
If using the VM, there might be some issue lead to the timeout problem.
Thanks

@DavidDDD

Some questions to confirm:
Is your host a virtual machine or a physical machine?
If using the VM, there might be some issue lead to the timeout problem.

my host is physical machine and system is Ubuntu22.04, and the avail disk is 369G, it’s enough.

Hi,

Could you provide the uart log for further review?
