issue with building Yocto on imx8mm-lpddr4-evk

[shai_b]

Dear Team,

My customer is trying to build Yocto on imx8mm-lpddr4-evk.

These are the commands he used to download the repo and build the image:

python3 ./repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-zeus -m imx-5.4.70-2.3.2.xml

DISTRO=fsl-imx-xwayland MACHINE=imx8mm-lpddr4-evk source imx-setup-release.sh -b build_xwayland

bitbake imx-image-core

The complied is completed successfully but after flashing the image into the device there was no response from the device (did not bootup)?

Please advise if the procedure above is correct?  

Waiting for your kind feedback, Thanks a lot.

KR,

Shai

@josephzhou1 ,

I've worked with the customer and we managed to flash the image into the iMX device.

since he builds the core image, it seems to be lack screen/display features.

if the customer would build the Multimedia does he need to do something in order to open the DSI port and display the xwayland feature or it's run by default?

Thanks in advance

mipi dsi is supported as default

Dear @joanxie and @josephzhou1, 

Thanks for your input, it looks like there is an issue with my customer's image due to the DSI not working properly (he gets a Black screen).

he will try to rebuild the Yocto image and I will open a new thread as needed.

Thanks and regards,

Shai
