Opi PC won't boot

[Drakoh]

As the title says, my OpiPC don't want to boot. It starts to boot, with UART console I can see u-boot loading and doing its job, but just when it would start the kernel the console gets borked with non-ascii characters.

After this, the board just hangs there.

 

I've tested with 3 different images (written out by Etcher), checked the images checksum and checked the SDcard with F3.

 

This setup worked fine a month ago, when I last had the time to play with it.

Since than, the board was just lying on my desk, turned off.
