IMX8MQ constantly restarting (L4.14.98)

[btodorov]

Hello,

I've i.MX8 Quadmax board and I'm trying to run imx-4.14.98-2.0.0_ga on it.

The problem is that the board is constantly restarting at boot:

resetting ...

What I did was

$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml
$ MACHINE=imx8qmmek DISTRO=fsl-imx-xwayland source fsl-setup-release.sh -b build-xwayland
$ bitbake fsl-image-validation-imx

Then deployed the images on sd card.

Any idea why is this happening?

BR,

how about trying the demo images from nxp official website？

“https://www.nxp.com/webapp/Download?colCode=L4.14.98_2.0.0_MX8QM&appType=license”

if you couldn't download it, try this link

"https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat..."

After I modified the uuu.auto in L4.14.98 and the demo images are working fine.

Any idea what might be missing in my manual build?

[joanxie]

the built image should the same as demo images, what built images did  you use? I remembered that I used 4.14.98 built image on my imx8mq board before, don't have such issue

[btodorov]

I just did"

$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml
$ MACHINE=imx8qmmek DISTRO=fsl-imx-xwayland source fsl-setup-release.sh -b build-xwayland
$ bitbake fsl-image-validation-imx

Then deployed the images on sd card.

Am I missing some step? Something related to uboot?

[joanxie]

how about replacing demo kernel images by your own built kernel images? could you have the same issue? did you download demo images to the same SD card, everything is ok, right?

[btodorov · Accepted solution]

Ok, it looks like I was using corrupted SD card or there were some issues with my card reader. Changed both and now I can boot with my custom build.

Thank you for the support!
