Olimex A20 OLinuXino MICRO board first boot

I have been scouting for a suitable SBC for some client work and came across Olimex A20 OLinuXino MICRO. The board is a bit pricey (55€) but does pack some serious punch. Getting the board to boot was a bit more complicated compared to - say a Raspberry Pi, but was completed after carefully reading the manual (RTFM does work). Some findings which may help someone - these apply for Linux image which can be downloaded from the Olimex website
  • If you power the board from mini USB OTG port the power LED WILL NOT LIGHT UP
  • when everything is OK, the green LED will first burn steady and will blink when the OS is running
  • The board boots only FROM THE MICRO SD SLOT
  • default output is HDMI
  • however THERE WILL BE NO VIDEO UNTIL THE WINDOW MANAGER IS RUNNING
  • the NETWORK IS DISABLED BY DEFAULT
  • sometimes you need to press the power button once to begin the boot sequence
Some of these are due to hardware limitations, but some are just a bit bizarre design decisions. Hope this list helps someone - I did waste some time for mainly two reasons
  1. I didn't read ALL the documentation (user manual, wiki pages and discussion forum)
  2. The power LED didn't light up - I kept switching power supplies until I figured this out
All in all - the board is reasonably well built - some solder joints look a bit shady but everything works OK. It is noticeably faster compared to Raspberry Pi and has plenty more connectors and possibilities. What I really like is the LiPo cell power option.
