There's a Bios/Firmware to start OS on the compact flash socket.
Is this starter open source or not ?
Can we transform it and flash it ?
I was wondering to have a pure C++11 Operating System and doing all
the low level resetting, ... in the starter firmware.
Is there some books which explain how the boot sequence works especially on this board ?
Here you can see Allwinner A10 boot process explained:
http://rhombus-tech.net/allwinner_a10/a10_boot_process/ (http://rhombus-tech.net/allwinner_a10/a10_boot_process/)
Allwinner A10 and A20 are quite similar chips so probably the same logic is used in A20.
You can try to find useful info in the A20 user manual:
http://dl.linux-sunxi.org/A20/ (http://dl.linux-sunxi.org/A20/)
or in the information published in linux-sunxi.org site
I will look at that, thanks.
