Flashing the BlinkyTape from Linux appears to brick the strip

I attempted to send over a sketch from the Arduino UI on openSUSE 13.1 and it stalled out and dropped the connection halfway through. It appears to have bricked my Blinkytape. I've tried doing the reset to get it to accept a new sketch, but it doesn't come back. Occasionally I'll see random lights flash, but it won't run any sketches (my own, or from the Blinkytape examples).

I've tried moving it back to my Mac where I was successful before, but it doesn't seem to work on either platform.

  • Here's the sketch I was attempting to upload:

  • Have you tried the reset procedure described here? http://blinkinlabs.com/blinkytape/docs/troubleshooting/ (part 5, about shorting the reset pins)
  • I have. A couple of times. The first couple of times it started to run the firmware, but within a couple of seconds, it died again. Now I can't even get that. It doesn't even show up in /dev anymore on Linux or Mac.
  • Hmm...you might have a hardware issue. Do you have access to another computer/OS to try this with?
  • For what it's worth, I had success reflashing my BlinkyTape with Ubuntu and Gentoo.
    So it's not a blanket "Flashing from Linux results in a brick" issue.
    From what I can infer, openSUSE 13.1 should have arduino version 1.0.5.
  • I successfully did it a couple of times myself, and I did it with no problems on my Mac until this incident. I suspect hardware issue as well. I can communicate just fine with my Arduino Uno in Linux.
  • Sorry you're having trouble- if it's a hardware issue, we'll get a new one out to you shortly.

    The reset procedure causes the tape to reset into bootloader mode, but it will only last for 6 seconds or so. Can you try to do the reset again (using your Linux box), then check the system log to see if it gets identified momentarily? Here are the steps:

    1. Connect the BlinkyTape to your Linux system

    2. Momentarily short the 'reset' hole to 'gnd' on the BlinkyTape controller using two pins, as described in the reset procedure. Touching them momentarily and then releasing should be fine.

    3. Check the console to see if the system detected any USB activity:
    dmesg | tail -n 20

    On my system (running Ubuntu 12.04), it shows me the following for a working BlinkyTape:

  • Here's my dmesg output. The cdc_acm driver appears to load correctly, and I even tried to flash the sketch, which reported a successful completion, but none of the LED's are lit or doing anything. I've tried it with several of the example sketches in addition to my own.

  • Hi darthzen - were you able to do bring the tape back to a working state while in Mac OS, using the reset and the 'Restore Rainbow' option in PatternPaint 0.2.0? Or is it still bricked even when you bring it back to the Mac?
  • It appears to be still bricked even on the Mac.
  • edited December 2013
    OK, that's not good - and when you brought it back to the mac, you used the reset procedure (as shown here: http://blinkinlabs.com/blinkytape/docs/troubleshooting/ ) correct?

    Sorry for all the questions - shoot me an email when you've tried that (if you haven't already) and we'll see about replacing that tape for you -- support@blinkinlabs.com
