Yocto using latest Jetpack 4.3 for Nano

Hello,
Is someone can help me building a Yocto image for the Jetson Nano with DevKit module which includes all gstreamer plugins regarding multimedia hardware acceleration (nvarguscamerasrc, nvcompositor, nvoverlaysink, …) We would like to have a Linux image as small as possible. We do not want to use Ubuntu as a target platform in order to minimize boot time and CPU usage.

I have seen this thread: https://www.konsulko.com/building-a-custom-linux-distribution-for-nvidia-cuda-enabled-embedded-devices/

However, this seems to be related to TX2 module.

Any guidelines would be appreciated.

Regards,
Jérôme

The meta-tegra layer works well:

I successfully generated a Yocto image for the Jetson Nano DevKit module with SDcard.

Here are my steps:
git clone -b zeus git://git.yoctoproject.org/poky poky-nano
cd poky-nano
git clone -b zeus-l4t-r32.3.1 https://github.com/madisongh/meta-tegra.git
source oe-init-build-env

Append the following text to build/conf/local.conf
MACHINE = “jetson-nano-qspi-sd”
LICENSE_FLAGS_WHITELIST = “commercial”
IMAGE_CLASSES += “image_types_tegra”
IMAGE_FSTYPES = “tegraflash”
GCCVERSION = “7.%”
CUDA_VERSION= “10.0”
IMAGE_INSTALL_append = " cuda-samples"
NVIDIA_DEVNET_MIRROR = “file:///home/jerome/Downloads/nvidia/sdkm_downloads”

Add the following layer to build/conf/bblayers.conf
/home/jerome/poky-nano/meta-tegra

To generate build, do
bitbake core-image-minimal

Jérôme

Does this no longer create an SDCARD image for the nano dev kit ???

Hi @scottkvps23,

Currently seems that meta-tegra does not include support by default to generate the sdcard image.
You can check the following information that can be useful:

actually it does, in a way you can flash the wic image and create an sdcard image with ./dosdcard
