Imx8-hummingboard-pulse is not booting-up

NXP i.MX8M Plus
1

Hello there,
I’m using hardknott-imx8mp branch from github - SolidRun / meta-solidrun-arm-imx8

When I prepared SD card and used with humming board Mate board, it boots up, but with Humming board pulse, same SD card is getting crashed. Following are the boot logs -

could you upload your image somewhere public so I can download and test it? That will probably be the quickest way to debug this. The crash is definitely happening because the imx sdma engine is not initialized, however the yocto recipe should be building everything so that is not a problem.

I found an image from solidrun humming board web page. I flashed sd card with that and board booted up correctly as expected.
Here I found that the image is a full image and NOT core-image-minimal. And I was building with bitbake core-image-minimal.

Now, I’m building the project with bitbake imx-image-full. I’ll check our custom carrier board with it and will update you soon.

Thanks
