Armbian Buster and Focal mainline kernel 5.10.y not booting on HC4

[beehive]

The images where applied with Balena etcher.

Petitboot was removed as described.

The PSU was included in the bundle (15V 4A).

Odroid Ubuntu works fine.

 

The boot process stops at:

 

Booting kernel ...

 

I tried the following Images (none of them works):

 

• Armbian Buster - mainline kernel 5.10.y
• Armbian Focal - mainline kernel 5.10.y

 

What am i missing ?

Any help appreciated.
