ccardimx28js boot freeze

I’m using the ccardim28js and want to change it to Yocto Linux.

I’ve successfully created my own image files with bitbake. There are the uimage, rootfs and the dtb images.

After transferring the uimage and rootfs the system trys to boot but it freezes after “Starting kernel …”.

I figured out that i have to use the .dtb file. But I’m totally stucked, what to do with it. Can somehelp me with information for the ccardimx28js?

Thank you

Have you tried precompiled images from here:
ftp://ftp1.digi.com/support/digiembeddedyocto/1.6/1.6.9/images/82003583_G/

have you tried to build yocto images without making any changes? this should work as well
