Deploying the eIQ Sample Apps to an i.MX8 board

[#1]

After setting up an Yocto build environment as described in the L4.19.35_1.0.0 BSP Yocto Project User's Guide, apply the attached patch to the meta-fsl-bsp-release layer:

<yocto_dir>/sources/meta-fsl-bsp-release$ git am eiq-sample-apps-Add-recipe.patch

To include the applications in the image, add the following line to local.conf:

IMAGE_INSTALL_append += "eiq-sample-apps"

This will include all applications from the eIQ Sample Apps repository to the built image.

Hello:

           I encounter a error when applied the attached patch.

ERROR: Nothing RPROVIDES 'eiq-sample-apps' (but /home/duxy/fsl-arm-yocto-bsp/sources/meta-fsl-bsp-release/imx/meta-sdk/dynamic-layers/qt5-layer/recipes-fsl/images/fsl-image-qt5.bb RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'eiq-sample-apps' is unbuildable, removing...

ERROR: Required build target 'fsl-image-qt5' has no buildable providers.
Missing or unbuildable dependency chain was: ['fsl-image-qt5', 'eiq-sample-apps']

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

      how to resolve it?    Before applied the patch， I have compiled the eIQ image successfully.

Hi coindu‌,

Could you please confirm that the patch was successfully applied? Does the eiq-sample-apps folder exists in meta-fsl-bsp-release/imx/meta-ml/recipes-apps/eiq-sample-apps? What BSP release are you using?

Thanks!

Vanessa

I reference 《UM11226.pdf》 to set the environment

repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_machinelearning.xml

$: EULA=1 MACHINE=imx8mqevk DISTRO=fsl-imx-xwayland source ./fsl-setup-release.sh -b build-xwayland $: echo "BBLAYERS += \" \${BSPDIR}/sources/meta-imx-machinelearning \"" >> conf/bblayers.conf

meta-imx-machinelearning/recipes-libraries/tensorflow/tensorflow_1.12.0.bb  modify 

COMPATIBLE_MACHINE = "(imx8qm|imx8mq|imx8mm)"

bitbake fsl-image-qt5

[vanessa_maegima]

Could you please modify the COMPATIBLE_MACHINE in the eiq_sample_apps recipe as you did for TensorFlow and let me know how it goes?

COMPATIBLE_MACHINE = "(imx8qm|imx8mq|imx8mm)"

My patch applies on top of a newer release L4.19.35 but let's try to make this work on L4.14.98

[coindu]

It do not work to modify COMPATIBLE_MACHINE.    

It doesn't matter, I still compile according to the documentation

[vanessa_maegima]

Please try adding the following line to conf/bblayers.conf:

BBLAYERS += " ${BSPDIR}/sources/meta-fsl-bsp-release/imx/meta-ml "

Hi

The Yocto Project User's Guide say that eIQ is integrated in meta-eiq, but this layer doesn't exist.

There is a meta-ml: is ti the same thing?

Hi philippemidol-monnet‌,

Yes, you are correct. I will ask for this to be updated.

Thanks for reporting.
