RaspberryPi stopped booting

Sat Nov 02, 2013 7:40 pm

My RaspberryPi suddenly stopped booting. When I power it on, green LED turns on for a second or two, but then nothing happens (nothing on screen - says "No input signal", nothing on serial port). I tried several SD cards that used to work with it, and I tried two different power supplies (Nokia 1.2A, Logitech 1A, both of which used to work with Pi), and nothing changes.

SD cards are being read, because if I remove start.elf, the green LED starts blinking 3 times every few seconds when I power it on. Any ideas what could be wrong, or what else I should try?

My Raspberry Pi is one of the older Model B's with 256MB RAM.

OK, since I posted this, I tried a few more times, and now I sometimes get the rainbow square on the screen. On the serial port I see this when booting Linux:

Code: Select all

Uncompressing Linux...

uncompression error

 -- System halted
(regardless of the card; I have verified that the kernel image is fine).

I also tried booting a card with RiscOS, which gave me this on serial console:

Code: Select all

I suspect the power supply even though you've tried 2 that worked before. Have you added any other hardware peripherals such as wireless dongle, etc that could be drawing more power?
