Jetpack6.2 to jetpack5.1.5

royayeazadi · July 9, 2025, 5:23am

hi every body;
I am using an Orin NX and have installed JetPack 6.2 on it. For some reasons, I need to have JetPack 5.1.5 on the board. I can do this using SDK Manager, but I am unable to do it with the command line. How can I resolve this issue?
I am using the following command for flashing.
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit-super internal

Hi,

Please refer to JP5.1.5 Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation .

The command is slightly different to JP6.2

Thanks

thanks for your reply,
I reviewed this document and followed the procedure, but after the flashing is complete, the board only gives me a shell, and there is no operating system.

Is my issue solvable?

DavidDDD · July 11, 2025, 3:46am

Hi,

Is your Orin NX plugged into any Ethernet devices?
If yes, please remove it and boot again.

Also the command mentioned in UEFI Adaptation — NVIDIA Jetson Linux Developer Guide could change the boot order.

Thanks

royayeazadi · July 12, 2025, 10:15am

thanks for your reply,
No Ethernet device is connected to the board.
We used the following command for flashing, and the result was the same as before.

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 jetson-orin-nano-devkit-super internal

royayeazadi · July 14, 2025, 7:40am

Is my issue solvable?

DavidDDD · July 14, 2025, 9:52am

Hi,

One question to confirm:

Is your carrier board a dev kit or a custom board?
Also please provide the serial console log during flashing process for further check.

Thanks

royayeazadi · July 14, 2025, 1:35pm

Hi,
thanks for your reply,
I have a custom board. the serial console log is attached.

royayeazadi · July 16, 2025, 7:56am

My problem still hasn’t been resolved.

DavidDDD · July 16, 2025, 9:37am

Hi,

Some questions to confirm:

You could flash JP 5.1.5 using SDK Manager, but flashing it via the command line might fail?

Thanks

royayeazadi · July 16, 2025, 10:28am

Hi,
Yes, we could flash JP 5.1.5 using SDK Manager, but flashing it via the command line might fail.

DavidDDD · July 16, 2025, 10:31am

Hi,

Got it.

Based your log, it might enter in PXE boot.
Could you try to enter Boot Manager in UEFI and manually choose NVMe as a boot device.

Jetson UEFI firmware (version 6.1-39721438 built on 2025-03-04T09:36:16+00:00)
ESC   to enter Setup.
F11   to enter Boot Manager Menu.
Enter to continue boot.

Thanks

royayeazadi · July 16, 2025, 10:36am

I’ll check on this and let you know.

royayeazadi · July 16, 2025, 11:20am

When I select the option to boot from NVMe, no changes are observed, and practically, there is no possibility of selection.

royayeazadi · July 17, 2025, 10:54am

I hope the issue gets resolved.

DavidDDD · July 18, 2025, 6:15am

Hi,

Sorry, we need the more log to reivew.

Please use sdk manager to flash your device again, and provide two log:

press EXPORT LOG button and attach the sdk log
Record the serial log during flashing

Please use command line and also provide two log:

flashing log
serial log

One question to confirm:
How do you prepare the command line way bsp?
Do you flash it under the ~/nvidia/nvidia_sdk/ or download the bsp from JetPack Archive | NVIDIA Developer?

Thanks

royayeazadi · July 19, 2025, 10:00am

I used sdkmanager to create L4T and set a local path for it.
I’m flashing and will send you the log.
