  • I connect this fine cable to the A20 board and then the cable to my VGA-compatible TV set, then I power the board and a LED turns on but there is no output on the TV. Where I did wrong?
  • You need to download the default Debian Linux image and use the script to change the default video output configuration. More information on how-to do it might be found at the wiki article: A20-OLinuXino-MICRO wiki
  • There is no Android on the NAND memory! The boards with NAND used to have Android already loaded! What happened?
  • We no longer load Android on the NAND memory of the boards. You can upload Android following the FAQ section of the wiki article of your board.
  • I can't make Android work with the VGA cable. Please send me an image with the correct configuration settings.
  • We can't either, despite our numerous attempts. Please note that: we neither have nor provide an Android image for VGA screen.
  • How long this board will be available?
  • This board will be available forever
