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.
What do I need to connect one of the Olimex-made displays to the board?
We are working on an adapter at the moment, which is yet to be released. Note that A10-OLinuXino-UEXT adapter is not suitable for A20-OLinuXino-LIME2. The layout of the LCD connector of A10-OLinuXino-LIME and A20-OLinuXino-LIME2 is different.
I bought a supported LCD 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?
The board works in the commercial temperature range 0+70C
