Understanding board rev

Hi all,
I recently got a new batch of Orin NX 16GB and I was restoring the image I previously created with

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

The image was created with a previous ORIN NX 16GB batch and I flashed Jetpack 5.1.1 on it.
Unfortunately I faced the error You are trying to flash images from a board model that does not match the current board you're flashing onto.

I checked the script and apparently the problem is in board_spec:
In the image’s nvpartitionmap.txt the board_spec is board_spec,3767-300-0000-H.2-1-1-p3509-a02+p3767-0000- while the current batch apparently is board_spec,3767-300-0000-J.1-1-1-p3509-a02+p3767-0000-

If I read it correctly, H.2 and J.1 are BOARD_REV but I have not found more information about its meaning.
Why the two REV are different? Is it a problem if I change nvpartitionmap’s board_spec to J.1 instead of H.2?


You can disable that check where you saw this print " `You are trying to flash images from a board model that does not match the current board you’re flashing onto", if you are sure it is just revision difference.

I actually changed the revision number in the board_spec to match it correctly.
Btw, is it just an id that identifies the batch or it means something else?

Thank you


Just want to clarify one point here. If you don’t use clone/backup tool, is this module able to get flashed ?
I mean using initrd flash tool directly.

Hi @WayneWWW , Yes I usually flash it via:

sudo ADDITIONAL_DTB_OVERLAY_OPT=“BootOrderNvme.dtbo” ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal

after editing cvb_eeprom_read_size to 0x0 in Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb2-bct-misc-p3767-0000.dts

Hi, can you share the module part number of two modules? It is a number containing “3767” on a label or printed on board.

In additon, the H.2 and J.1 is for internal usage. Same PN means same product regardless of that letter.

Hi @Trumany
Sure, both the batches share the same module part number, printed on the PCB:

Model P3767 180-13767-DAAA-A13 CAN ICES-003(B)/NMB-003(B)
