allwinner/a20/EOMA68-disassembly
EOMA68-A20 Disassembly If you need to disassemble the EOMA68-A20 board then please follow this procedure: Be patient, don't use excessive force You only need to remove the "top" shield (same side as uSD slot) to reach usb-boot jumper. Start from the outside (hdmi contacts etc) and work your way towards the EOMA68 contact. Push the shield gently to the side to loose its grip. Wiggle it a bit working up the edges. The metal is glued to the EOMA68 connector with adhesive tape. When reaching the EOMA68 connector...

allwinner a10/Building Linux
Building Linux This document attempts to provide recipes for building different Linux kernel versions. Linux 3.4 was used to test the A10 and A20 boards, but it may now be considered "legacy" and would not be the basis for ongoing software support. However, it may still be useful for board testing. Linux 3.4 Since the 3.4 kernel will suffer from similar compilation issues to those experienced in Building U-Boot, a Buildroot Toolchain may need to be prepared before attempting to build the Linux kernel itself....
