Hello community,

[RidgeRun](http://www.ridgerun.com) is happy to anounce that we will be providing professional Yocto support for Jetson boards. We will also be contributing to [meta-tegra](https://github.com/madisongh/meta-tegra) community layer with new features and characteristics (Gst-inference, DeepStream, or other video and/or AI) and helping companies interested in using Yocto. Currently we are validating all supported features and testing them. You can check our developer’s wiki (work in progress) for easy instructions on how to use Yocto built images on your Jetson boards.

Hi @fabian.solano,  
thank you for providing details for Yocto support for Jetson boards.  
I tried to run a build for **jetson-xavier** ,

```
Build Configuration:
BB_VERSION = "1.46.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "ubuntu-18.04"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "jetson-xavier"
DISTRO = "poky"
DISTRO_VERSION = "3.1.1"
TUNE_FEATURES = "aarch64 armv8a crc"
TARGET_FPU = ""
meta                 
meta-poky            
meta-yocto-bsp = "dunfell:0fc9d32ae11ebb53aa33342f50887c1e692a1f32"
meta-tegra = "dunfell-l4t-r32.4.2:7600b655471b94db0251fd459ac4bb069056e725"

```

However once it ended I am wondering how to load the generated O.S. into the eMMC.  
In your document the chapter **Flash image to Jetson platform** refers to an unexistent **tegraflash.zip** and **doflash.sh**.

Could you clarify how to do that?  
Thanks

Hi @MarukoBG,

To get the tegraflash tarball you need to add the following lines to your local.conf file (as specified [here](https://developer.ridgerun.com/wiki/index.php?title=Yocto_Support_for_NVIDIA_Jetson_Platforms#Compile_Yocto_image))

```auto
IMAGE_CLASSES += "image_types_tegra"
IMAGE_FSTYPES = "tegraflash"

```

Then after the bitbake command ended you need to create the deploy.sh script. I think the problem is that the latest meta-tegra branch (dunfell-l4t-r32.4.2) updated from .zip file to .tar.gz. Here is the updated script, I also updated it in our [developer wiki](https://developer.ridgerun.com/wiki/index.php?title=Yocto_Support_for_NVIDIA_Jetson_Platforms#Flash_image_to_Jetson_platform) for future reference

```auto
#!/bin/bash

image=$1
machine=$2

scriptdir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null && pwd )"
deployfile=${image}-${machine}.tegraflash.tar.gz
tmpdir=`mktemp`

rm -rf $tmpdir
mkdir -p $tmpdir
echo "Using temp directory $tmpdir"
pushd $tmpdir
cp $scriptdir/build/tmp/deploy/images/${machine}/$deployfile .
tar -xvf $deployfile
set -e
sudo ./doflash.sh
popd
echo "Removing temp directory $tmpdir"
rm -rf $tmpdir

```

Hi,  
I added the lines below to **local.conf** , but **tegraflash** tarball is not generated.  
May be caused by the jetson-xavier?

```
MACHINE = "jetson-xavier"
IMAGE_CLASSES += "image_types_tegra"
INHERIT += "rm_work"
IMAGE_FSTYPES = "tegraflash tar.gz wic.gz"

```

In the wiki there is a typo too ;-)

Can you share the output of the following command to verify which images are being generated?

```auto
ls -lha build/tmp/deploy/images/jetson-xavier/

So the tegraflash.tar.gz file is actually being generated.

```auto
-rw-r–r-- 1 koan koan 65M giu 19 14:25 core-image-minimal-jetson-xavier-20200619122451.tegraflash.tar.gz

```

Maybe you are running the script from the wrong path, and that is why the file is not found.

You should run the script, from the same directory from where you ran that command.

Hi @fabian.solano

I’ve tried building the Yocto image (according to [Yocto Support for NVIDIA Jetson Platforms - Yocto Support for NVIDIA Jetson Platforms](https://developer.ridgerun.com/wiki/index.php?title=Yocto_Support_for_NVIDIA_Jetson_Platforms)), by configuring the MACHINE environment variable to ‘jetson-xavier-8gb’ machine , however i have a 16GB Xavier.

Should it work on my machine? Is there another BSP layer for the 16GB Jetson Xavier?

Regards.  
Elad

Hi @ereelad,

If you set up the environment variable to just **jetson-xavier** it would be the default for the 16GB. Actually the 8GB is a side support by the community according to readme at: [GitHub - OE4T/meta-tegra: BSP layer for NVIDIA Jetson platforms, based on L4T](https://github.com/madisongh/meta-tegra)
