Hi @sosalrito , welcome to the forum.
If you meant Jetson Nano guide, please follow the below guide.
We will update the guide in the near future.
In code examples in the following guide, + means adding the line and - means removing that line. (It is silmilar to git diff)
For now, keyboard and mouse won't work. Please use SSH connection.
-
git clone https://github.com/webosose/build-webos.git
-
cd build-webos
-
sudo scripts/prerequisites.sh
-
Add the following command to weboslayers.py (in described in the guide)
('meta-tegra', 30, 'https://github.com/OE4T/meta-tegra.git', 'branch=dunfell-l4t-r32.6.1', ''),
-
./mcf jetson-nano-devkit
-

-
cherry-pick the following two commits and move files in meta-tegra/external/qt5-layer/recipes-qt/qt5 to meta-tegra/recipes-qt/qt6. And remove the qt5 folder.
git cherry-pick 47b14268ef9aaccf57604e1665612faa239c2223

If the build succeeds, BUILD/deploy/images/jetson-nano-devkit/webos-image-jetson-nano-devkit.tegraflash.tar.gz file will be generated. extract the file.
$ mkdir webos-image-jetson-nano-devkit
$ tar -zxvf ./webos-image-jetson-nano-devkit.tegraflash.tar.gz -C ./webos-image-jetson-nano-devkit
- run
dosdcard.sh. webos-image.sdcard will be generated.
(webos-image-jetson-nano-devkit) $ ./dosdcard.sh
- Plug in your microSD card to your computer and write
webos-image.sdcard to your microSD card.
Please replace [X] before execute the command. See Flashing the Image to find your own [X].
