Yun not working

Official Hardware Classic Yún
1

Sorry for my bad english,
I 've been programming with an Arduino Yun for two weeks by now. It suddenly stopped working, with no noticeable reason at all.

  • The rx light is the only one always ON (when I power the board)
  • The other lights are always OFF
  • My computer doesn't detect the board ( My USB ports don't work really well, but well enough to at least detect the board i think)
  • The board doesn't succed in doing the sketch I previously uploaded (when the board worked)
  • I've tryed doing the 3 resets, no changes at all
    What could be possibly happening? Please, I need help

Connect Yun with with an other computer for testing since Yun has hardware bug which has less power supply voltage (~4.5 V)

I just had the same problem, but managed to fix it.

I was fiddling with a serial communication sketch using the Yun and it froze up the same way. It would no longer connect to windows via the USB and its RX light was stuck on. I tried lots of things but this is how I fixed it.

  1. Disconnect everything

  2. Connect ethernet cable from Yun to the router

  3. Connect the Yun micro USB to the the computer (just for power)

  4. Wait a minute

  5. Go into the web-browser and type http://arduino.local

  6. You should see the login interface for the Yun (default pw: arduino)

  7. If you get this far then you are in business. What I did was loaded a sys upgrade following the instructions at: http://arduino.cc/en/Tutorial/YunSysupgrade. Be very patient here. When you put the SD card into the Yun turn it off and on and give it plenty of time to boot or whatever it does. When you're done confirm you can still get to the Yun home page.

  8. Then I opened the arduino IDE and connected to the Yun using the ip address in the 'ports' menu. The yun will tell you it;s IP address on the home escreen you get to at http://arduino.local (close this page before you try the IDE).

  9. I loaded the YunSerialTerminal sketch to the Yun and it was back in business!

It may be that you could simply load the new sketch using the network IP port that appears when you connect over the ethernet, but I'm not sure. It really did seem as if the Yun's processors had gotten into a squabble and needed counselling!

As you can tell from this I have little idea what I'm doing, but id did work for me. Good Luck.
