I tried to look for info and all info seems to indicate a problem of the sd card reader. I have a 256 MB raspberry pi (V 1.0 B1.1 - had been resting a bit) that doesn't boot.
I tried 3-4 different SD-cards of which 1 (high speed) has been reported as functional (I used multiple images: archlinux, debian, ...) and none boot. I'm using an adapter that was delivered with the pi (from rs), so this shouldn't be the problem.
The power-led is red and the sd led is constantly green. I tried to fiddle a bit with the sdcard-contacts, but nothing seems to work. The network light isn't on, no screen, no dhcp-requests, ...
Is it broken or is there something I could check (voltage-check or so?) to determine what the exact problem is?
