FAQ

  • I am an inexperienced user and I'm afraid to mess up initially. What are the most common errors in the initial start-up of the board?
  • The best idea is to download the latest Debian or Android image from the wiki and to pay attention if it is for microSD card or the NAND memory. After that ensure the image is properly written to the SD card or the NAND memory. Finally, if you are expecting video output problems, ensure the image is set with the proper settings for the display/monitor you are going to use. Double check if the power supply is sufficient (especially if powering a display from the board).
  • Can I use the Debian or Android image for A20-OLinuXino-LIME or A10-OLinuXino-LIME instead of the one for A20-OLinuXino-LIME2?
  • No. Both Debian and Android images are specfic for each board. Make sure the image that you download and use is specifically marked as suitable for A20-OLinuXino-LIME2. The prepared cards which we sell for the board are also different.
  • Hello, I made a shield for my LIME board. I now own a LIME2 board. Can I use the shield with the LIME2 design?
  • No. The LIME2 design swaps the signals of each row of each 0.5" step header. All four GPIO headers and the LCD header are affected. Shields made for LIME boards can't be connected directly to a LIME2 board.
  • 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.
  • What do I need to connect one of the Olimex-made displays to the board?
  • There are two scenarios depending on the display you have at your disposal. Typically you would need a single cable named "CABLE-40-40-10CM". For more information refer to this wiki article: how to connect display to a Lime board

    IMPORTANT: the cable and the connectors are very fragile - if you attempt to disconnect the setup by pulling the cable it might break! Furthermore - you might bend the board's pins! Use pliers or other suitable object to disconnect the connectors carefully!
  • I bought a supported LCD display and the required cables but when I connect it to the A20-OLinuXino-LIME2 I receive no image on the display. What do I do wrong?
  • The default A20-OLinuXino-LIME2 Debian image is set for HDMI output and HD resolution. To use LCD or lower the resolution you would need to start the shell script in the default Debian image.
  • What is the operating temperature range of A20-OLinuXino-LIME2-4GB?
  • The board works in the commercial temperature range 0+70C
  • How long this board will be available?
  • This board will be available forever
