Download the .rar file below and move/replace the existing file in **nvidia->nvidia\_sdk->JetPack\_6.2.2\_Linux\_JETSON\_ORIN\_NX\_TARGETS.** {% file src="/files/OXY1UMOFTYiWFeh8HgCa" %} {% hint style="info" %} If the folder is not present, try flashing the Jetson once, and the SDK should create the folder {% endhint %} ## Command Line: You could benefit from [Nvidia flash guide](https://docs.nvidia.com/jetson/archives/r35.3.1/DeveloperGuide/text/IN/QuickStart.html#to-flash-the-jetson-developer-kit-operating-software) . {% hint style="info" %} The difference here is you need to change the DIP switch on the carrier board to REC to boot in recovery mode. ![](https://2367252986-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLIgtGDAvVGkCKGOJb1bR%2Fuploads%2F2nRPtcWBtR7krSQiitPX%2FCleanShot%202024-05-31%20at%2018.27.04.png?alt=media\&token=f726c613-9426-459c-884a-de7a45d17a27) {% endhint %} ### Patched Jetpack 6.2.2 Command Line Procedure {% file src="/files/CMw2Rc9DuMdfiFUHwqP8" %} 1. Connect the Jetson to an Ubuntu 20.04/22.04 PC 2. Download the system image package with the following command ***wget *** ***wget *** 3. Execute the following commands to extract and assemble the flash package: ***tar xf Jetson\_Linux\_r36.5.0\_aarch64.tbz2*** ***sudo tar xpf Tegra\_Linux\_Sample-Root-Filesystem\_r36.5.0\_aarch64.tbz2 -C Linux\_for\_Tegra/rootfs/*** ***cd Linux\_for\_Tegra/*** ***sudo ./tools/l4t\_flash\_prerequisites.sh*** ***sudo ./apply\_binaries.sh*** ***sudo tar xf holybro\_jp622*** #copy holybro\_jp622 to the Linux\_for\_Tegra/ directory before excution 4. Put the device in Recovery mode 1. If the device ID is (7323/7423/7523/7623) when executing the ***lsusb*** command, the device is in recovery mode 5. Flash to SSD using the command below ***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*** 6. System Backup and Recovery 1. Backup image (enter Recovery mode): ***sudo ./tools/backup\_restore/l4t\_backup\_restore.sh -e nvme0n1 -b jetson-orin-nano-devkit-super*** 2. Flash the device using the backup image (enter Recovery mode): ***sudo ./tools/backup\_restore/l4t\_backup\_restore.sh -e nvme0n1 -r jetson-orin-nano-devkit-super*** ## Important procedure if the SSD has preinstalled Jetpack After the system is cloned to a new SSD, we connect the SSD and Jetson module to the baseboard, enter the force recovery mode, and connect to the computer.\ On the computer used to flash the firmware with the SDK manager, navigate to the folder: nvidia ->nvidia\_sdk, find the target version Jetpack folder, open it, and open the terminal at the folder location.
Once in the terminal, enter the command below:\ sudo ./flash.sh --no-systemimg -c bootloader/t186ref/cfg/flash\_t234\_qspi.xml jetson-orin-nano-devkit mmcblk0p1 {% hint style="info" %} In the latest Jetpack, the file path is bootloader/generic/cfg/flash\_t234\_qspi.xml {% endhint %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.holybro.com/autopilot/pixhawk-baseboards/pixhawk-jetson-baseboard/flashing-guide.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
