Hi @joanxie ,
Step #1 : Create bsp folder and move to inside
mkdir imx-yocto-bsp && cd imx-yocto-bsp
Step #2 : Sync the bsp source code
repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-zeus -m imx-5.4.70-2.3.2.xml
Step #3 : Setup the build environment
DISTRO=fsl-imx-xwayland MACHINE=imx8mpevk source imx-setup-release.sh -b build-xwayland
Step #4 : Add branch=main into armnn-onnx recipe
vi ../sources/meta-imx/meta-ml/recipes-libraries/armnn/armnn-onnx_1.3.0.bb
...
SRC_URI = "git://github.com/onnx/onnx.git;branch=main"
...
Step #5 : Bitbake full image
bitbake imx-image-full
Best Regards,
K.
