[RaspPi] Faintly glowing steady green LED on Raspberry Pi
I got some serious issues with one of my Raspberry Pi, Modell B Rev. 2.0.
With an recent image, the Raspberry Pi refused to boot, but did only light up the red ACT LED as well as an really faintly glowing steady green PWR LED.
After my shop of trust sadly declined to help me with that issue, I tried to come up with every possible fix possible.
So, what can it be?
- Powersupply not beefy enough
- Micro USB Cable damaged
- Image was damaged during download / extract
- SD Card is not correctly flashed
- SD Card is damaged
- Wrong SD Card Type or RPi does not like it
- High Power drawing devices attached to USB Port
- SD Card Slot on the RPi is damaged / no contact
In my case, the solution was quite easy:
The SD Card did not connect correctly to the SD Card Reader in the RPi.
I just needed to rebend the legs of the SD Card Slot on the RPi, after that, it just worked perfectly again.
The faintly glowing green LED says that the bootcode.bin could not be loaded, the first file that is pulled from the SD Card.
So it is a good hint for everything what could have gone wrong.
Other than that, a lot of good hints are shown on: http://elinux.org/R-Pi_Troubleshooting
