Odroid c2 no ping

Hi, I’ve imaged a 128gb sd with DietPi_OdroidC2-ARMv8-Buster. Left the config default, but also tried disabling ipv6 and wifi, and enabled headless, accept license and configured static IP, in various combinations. Waited for > 30 min, but the odroid doesn’t ping. The blue led blinks (heartbeat). Ubuntu and debian work.

I also haven’t got HDMI (when not enabling headless of course), but I also have that with Ubuntu and debian, could be my cable/converter.

How can I troubleshoot this?

Thanks

Nevermind, replaced SD, working now.
