• it's highly recommended to power via header with quality and powerful (3A) PSU - if you want stable operations and overclocking? In another words - don't even try to power via stock micro USB power connector since your board will suffer from regular crashing and might not even boot up.

• to boot from SD card you need to press and hold a button on the back side of the board and power on. This erases bootloader on eMMC and now you can boot from SD. In case of troubles use this tool to restore stock bootloader.

• known issues: MALI and video acceleration libraries are not installed yet

• overclocking to 2.2Ghz is possible with (patched) mainline kernel. Enable with:

    echo 1 > /sys/devices/system/cpu/cpufreq/boost		# enable turbo
    nano /etc/default/cpufrequtils 						# adjust new limit
    /etc/init.d/cpufrequtils restart 					# restart cpufrequtils
