I am using my raspberry pi 2 model B as a server run jessie. Suddenly, it cannot boot and the RED and GREEN leds on without blinking. I took the sdcard and opened it in laptop, I could navigate through the sdcard. "scan for fix" said the sd card was okay.

I put the sd card on my raspberry pi 1 B+. it works flawlessly. Whats wrong with my pi 2? Can anyone help to make it run again?

TIA

  • Is your power supply sufficient(above 2 amps) to power the Pi? – Mohammad Ali Nov 4 '16 at 13:51
  • Should be enough since it used to be working and the same power supply can power my other raspberry pi B+. – dadinugroho Nov 5 '16 at 0:38
  • The Pi two draws more power as it has more CPU cores, but what is more likely is that there is a problem with the Pi, I'd recommend that you try a different sd card and see if that works for you – Mohammad Ali Nov 5 '16 at 0:57
  • Yes, I am afraid problem with my pi 2 since the same sd card were reimaged and still both led on but not blinking. I need to buy new sdcard first before I can try again with another sdcard. – dadinugroho Nov 5 '16 at 14:20

A lack of blinking of the green LED frequently indicates an issue with the SD card or the OS (see this troubleshooting page for more details). Since it is working for you on another Pi, the SD card seems fine, but you may have a version of firmware that is not supported. When I got my Pi 2, I was unable to boot it with the SD card from my Pi 1.

  • The funny thing is that it used to be working fine for almost a year. Suddenly, it stopped working last week. But, the same sd card run fine on pi B+. – dadinugroho Nov 5 '16 at 0:39
  • Note the solid green led (no blinking) does not indicate an issue with the OS. It indicates an issue with the card or card reader -- it has not even gotten to the point where it has attempted to load an OS. Exactly the same thing will happen with no SD card inserted (which is not "an issue with the OS"). – goldilocks Nov 25 '16 at 16:24
