In the Makers area, it is common to make oleore boards based on Arduino. Making boards with ATMEGA32 chips is a great way to get started with Makers, both as a CAD experience and as a soldering experience. In the same way, with F1C100s / 200s, it will be possible to quickly make an oleore board that runs Linux.

Preliminary research to make a board.

--Allwinner and tablet makers are repeatedly violating the GPL

  • http://linux-sunxi.org/GPL_Violations --Isn't Backdoor included in the vendor's Kernel? There is a story
  • "Allwinner has also been accused of including a backdoor in its published version of the Linux kernel."
  • https://en.wikipedia.org/wiki/Allwinner_Technology

So far, no GPL violations have been confirmed with the F1C100S / 200S.
