RPi Zero won't boot

[diffusae]

Hello!

I've tried the RPI-B snapshot image for a Raspberry Pi Zero and it ends
up in a boot loop just after u-boot. I can not connect a keyboard to
hold the screen. It might be better to solder the GPIO header and use a
USB to TTL serial cable.

Maybe you have a suggestion of what went wrong?

According to the Wiki it should work with the RPI-B snapshots.

Thank you in advance
