I have the same problem. I selected all sd/mmc related drivers from menuconfig to be built and installed, but still not working.

Boot logs are attached.

I think boot is not contuniuing (there is no code) so there is this problem.

If you can, download newest version on the net.

Thanks for info. ​

Is there more new version than linux-4.19.94.tar.xz ?  (I used linux-4.19.94.tar.xz )

You can look at this site...

我在使用DK1的时也�?�到这个问题，对比�?程是一致的，目�?怀疑相关的命令有细微的错误。

Hi,

Issue confirmed - reproduced, investigation ongoing.

Hi all,

Just to double check:

did you well update your DK2 board with the V1.2.0 starter package (before updating the uimage with drm modification) ? I mean reflashing completely your sd card with V1.2.0.

The pb was found in the wiki article:

PC $> make ARCH=arm multi_v7_defconfig

should be:

PC $> make ARCH=arm multi_v7_defconfig fragment*.config

The article was updated accordingly. Thanks for pointing this and sorry for the inconvenience !

When I try:

PC $> make ARCH=arm multi_v7_defconfig fragment*.config

inside kernel source folder I get:

no matches found: fragment*.config

But, when I execute the command with the right fragment path:

PC $> make ARCH=arm multi_v7_defconfig ../fragment*.config

I get the following errors:
