[U-Boot] u-boot hangs after reboot

[Mike Mildner]

Hi all,

i'm new to this list...

I have a strange problem with my Olimex-olinuxino-micro-emmc (Allwinner A20):

I've tested u-boot-v2016.07/09/11 2017.03/05/09 - all this version hangs after reboot.
Only reseting or repowering helps.
On Display i get this:

U-Boot SPL 2016.09 (Oct 04 2017 - 08:12:07)
DR

The version u-boot-v2016.03 reboots fine and always.

Any ideas or hints?

Thx Mike
