I've been at this now for 2 days, googled various bits and pieces several hundred times and not really sure where to go from here.
Using my Kingston 4GB MicroSD HC (class 4) (exists in verified list) - I simply can't get Raspbmc, OpenELEC or Debian "Wheesy" images to work. They all get stuck prior to actual booting with the OK-light flashing 3 times before a pause (indicating a loader.bin not being able to be found).
The card works well in Windows, I can see the files present, and I've tried replacing some of them with the most up-to-date official ones from Git - same result.
Bad SD card you say? Maybe, but the latest Debian Squeeze works perfectly every time using the same approach as the others. Wheesy does not work but end up the same way as the others.
Tried this using both a laptop reader and an USB-reader from windows 7. (formatting with the HP tool and using win32diskimager to write the img-files.)
Is it a card issue? Full-size-adapter issue? (in both cases - why do the debian squeeze one work every single time?) or what could it possibly be?
Whilst the debian build is of most use, it would be nice to at least be able to try out others - getting past the flashes and into an OS. (f.e. check if the DWA-140 (rev. B3) work in Wheesy).
Same issue happens with nothing attached but the power supply (1200 mA)
Please, any suggestions would be welcome.
