It now boots!

After checking the (brand new) SD card on Windows, I discovered and removed the extra ".dot" files that Mac OS X leaves on the disk. After manually removing these with Windows,
Simply download this file (click "View Raw") and replace the bootcode.bin that is on the SD card (drag and drop the file with Mac OS X Finder)There is a bug in the distributed version of bootcode.bin which causes problems with some sdcards. Try this version: https://github.com/raspberrypi/firmware ... otcode.bin
I will try and explain with photos. The solder falls into the little holes and keeps the contacts down. The contacts cannot rise to the proper height. The photos also show one contact being done but I had to do all of them.Remember to clip the contacts back in.mnbf9rca wrote:What do you mean you "clipped the ends of the contacts out"?

Ahhh awesome. So maybe somehow its corrupted itself/the sdcard? I did try re-imaging this card but nothing. I guess I should go buy another sdcard and try again. I'm guessing the hard reset borked the fs. So if this is gonna be something I have to do every week or so, a hard reset, is there a way to make the fs more robust? Because having to reinstall the OS every week is gonna get old. Its raspbian ext3 iirc. Would using a SDD instead of sdcard help? I get the feeling the sdcard drivers/system just isnt cut out for server use?PaulCheffus wrote:Hipermaband wrote:Cycled power, now just get red power light.

What the flashing means

Might be worth copying the files from here back to the boot partition using whatever computer you used to create the image.

You are correct in that there could be many causes. I was lucky in the sens that I have a friend with a working Raspberry Pi and I could confirm with him that my power supply and SD card was working. So I knew that it had to be a problem with my Raspberry Pi. If the green OK LED lights dimly it shows that the Raspberry is trying to access the SD card without success. The LED is dim because the Raspberry Pi is in a loop. This led me to the SD card holder. If the card is corrupt or not compatable you may get different indications from the LED. Hope you get a solution soon.mnbf9rca wrote:very clear - thanks! i'll give that a go, although i think there are many causes with similar symptoms; for me, for example, reformatting the same SD card back restores "service".
