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).
What do I need to connect one of the Olimex-made displays to the board?
At the moment you would need two 40 pin cables (named CABLE-40-40-10CM and CABLE-IDC40-15cm) and a small adapter board called A10-OLinuXino-LIME-UEXT. In future, a single cable would be avaialable.
I bought A13-LCDxx but when I connect it to the A20-OLinuXino-LIME I receive no image on the display. What do I do wrong?
The default A20-OLinuXino-LIME Debian image is set for HDMI output and FullHD 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-LIME?
The board works in the commercial temperature range 0+70C
