MCIMX93-EVKCM About the eIQ demo at yocto

[Ryo_Aoki]

Hi community.

I want to demo eIQ using MCIMX93-EVKCM.

(about MACHINE LEARNING UG  11.2 TensorFlow Lite Demos for i.MX 93)

A demo image is created with reference to the following document.

  ..i.MX Machine Learning User's Guide Rev. LF6.1.1_1.0.0 — 31 March 2023

  ..i.MX Yocto Project User's Guide Rev. LF6.1.1_1.0.0 — 24 April 2023

But i can't run the demo because there is a problem with file reference.

The image was created using the following procedure.

$ repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-langdale -m imx-6.1.1-1.0.0.xml

$ repo sync

$ DISTRO=fsl-imx-xwayland MACHINE=imx93evk source imx-setup-release.sh -b build-93evk

　Add the following to local.conf

　　IMAGE_INSTALL:append = " python3-git python3-wheel“

　　IMAGE_INSTALL:append = " tensorflow-lite-ethosu-delegate“

　　TOOLCHAIN_TARGET_TASK:append = “ tensorflow-lite-dev onnxruntime-dev” 

$ bitbake imx-image-full

The manual says /usr/bin/eiq-examples-git exists.

But the eiq-examples-git folder exists only in /run/media/root-mmcblk1p2/usr/bin/.

I think that it is necessary to correct the reference destination of the library and the module if this folder structure is left as it is.

Is there anything I need to do to make it work as documented?

Paste the result of the df command.

I haven't built this image for eIQ, let me reproduce this and tell you the result

Hi Joan.

This issue is probably resolved.

The cause was a mistake in the boot mode, and it was booting from a different place than expected.

After correcting the boot settings, the eiq sample folder existed in the expected folder.

Sorry for the cheap mistake.This thread will be closed.

thank you for your support.

Best regards.

Hi Joan.
Thanks your reply.

I created the image with reference to the documentation,
but any help on how to fix it would be appreciated.
