I run Raspbian. Everything worked fine until now, when it seems I can't use any command on my Raspberry Pi. I tried to reboot. And now it doesn't connect to wifi.

@raspberrypi: sudo su

-bash: /usr/bin/sudo: cannot execute binary file


@raspberrypi ~ $ ls /usr/ Segmentation fault

After connecting to a display, I get the following log. (ilustrated in a picture)

I think you will have to re-image the SD card.

You seem to have serious corruption.

Any idea what caused the problem?

  • well, I don't have a clear idea. I get alot of "Segmentation fault" errors, when recording using a Raspicam and cancel the execution. I ignored them. But i don't think this would have been the problem. – iulian Jun 15 '15 at 19:22
  • I should have checked that you get the same problem with commands after re-boot. Or is it just a wifi problem after re-boot? – joan Jun 15 '15 at 19:39
  • after reboot my raspberry doesn't work anymore. I will connect it to a display to see if raspbian boots. – iulian Jun 15 '15 at 19:45
  • This isn't necessarily because of fs corruption, but I agree you might as well start over again by re-installing the OS. I also recommend you use the most recent Raspbian image if that isn't what you have. It wouldn't just be cancelling execution either, although that is a puzzling statement since something that segfaulted is already dead and cannot be cancelled. Unfortunately diagnosing it via online Q&A is not very feasible, so you will have to settle for mysterious. – goldilocks Jun 15 '15 at 19:59
