Unable to boot. Blinks orange after 3s & continues to stay in green forever.

0 votes


The the hardware powers on with solid green, blinks orange once after 3s BUT never becomes solid orange & does not get detected.

Here's what I have tried so far and they all resulted in failures:

  1. Connected miniUSB cable to 2 USB2.0 ports of my laptop and used the microSD card and the USB-to-MicroSD card reader shipped with A33 as-is for boot.
  2. Used SDFormatter (www.sdcard.org/downloads/formatter_4/) and formatted the microSD card using the provided USB-to-MicroSD card reader; Followed instructions on jevois.org/start website; Downloaded & unzipped the image from (jevois.org/data/jevois-image-latest-8G.zip); Used the recommended 'Etcher' program on Windows7 x64 PC and re-flashed the microSD card.
  3. Repeated the above step#2 except, used the USBwriter, USB image tool and Win32 Disk Imager as recommended on (jevois.org/doc/NewMicroSD.html) on the same Windows7 x64 PC and re-flashed the microSD card.
  4. Repeated the above step#2 except used Ubuntu 16.04LTS x64 machine and re-flashed the microSD card. I confirmed the files on microSD card with the file-tree-structure described on jevois.org/doc/MicroSD.html and they appeared correct.
  5. Used different microSD cards (Samsung PRO+ microSDHC & SanDisk Ultra microSDHC) and microSD-to-SD card adapter instead of USB-to-MicroSD card reader; Used a 2A cellphone charger; Made sure the microSD card is inserted properly and Repeated step#2,#3 & #4.

After trying all possible options, I am basically clueless right now. I would like to know if I missed any steps? 

I assume the image file (jevois.org/data/jevois-image-latest-8G.zip) is updated and valid. Could there be an issue with the hardware?

Sorry to hear about that. You may have the same issue as this post or maybe your unit is faulty (with a 2A charger, it should definitely get to the solid orange state).

Please contact us through your kickstarter account and we will send you a replacement unit to try out, which we will test again here before shipping.

Thank you for your response.

I tried using the 2A charger which I've been using for Raspberry Pi3. I also tried connecting the Ycable to another Ubuntu machine having two usb3.0 ports. Unfortunately, I did not get any successful results.

I can certainly contact you on kickstarter.
