# Flashing guide

{% hint style="info" %}
Note: There are scripts to help you do the necessary basic setup after flashing Jetson on Holybro's Github page:

&#x20;<https://github.com/Holybro/holybro-jetson-companion>
{% endhint %}

{% hint style="info" %}
Currently, the Holybro Jetson baseboard only supports Jetpack versions 5.1.2 to 6.0 and 6.2.2.
{% endhint %}

Two methods to flash the board:

### SDK Manager:

This is a GUI-based solution by Nvidia which can be found from the link below:\
\
<https://docs.nvidia.com/sdk-manager/install-with-sdkm-jetson/index.html>

**Note:** Keep in mind that at the time of writing this document, we chose to install Jetpack 5.1.2.

#### Extra procedure for Jetpack 6.2.2

For Jetpack version 6.2.2, a patch is required to install on the host computer.

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) .&#x20;

{% 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.&#x20;

{% endhint %}

### 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 %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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=<question>&goal=<endgoal>
```

`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.
