Linux 4.0 (4.1 on june 25) kernel on Allwinner A20/Cubieboard2

Thanks to the hardware and software development work of AllWinner, to the Linux mainlining effort of the Linux-sunxi community to improve and push driver into main line Linux kernel sources and to the integration work of ArchLinux and ArchLinuxARM communities, the Cubieboard2 (using Allwinner A20 SoC) since this night officially use 4.0 kernel as default with ArchlinuxARM. Before this date an old Linux kernel 3.x branch was used.

* Linux XXX 4.0.5-2-ARCH #1 SMP Fri Jun 12 20:03:44 MDT 2015 armv7l GNU/Linux

This means that :
* Lots of NAND flash can be used for system
* CPU frequency is well managed now
* Most of driver are integrated and probably really stable.

25 june update, 11 days after the 4.0 : A new update occured today with linux kernel 4.1
* Linux XXX 4.1.0-1-ARCH #1 SMP Tue Jun 23 23:24:14 MDT 2015 armv7l GNU/Linux).

Cubieboard or other SBC remote control methods

* Serial port
* SSH + X11
* X Protocol

Serial port/UART/RS232

If there isn’t network inside U-Boot boot sequence, of for other reason. Connecting using (replace the x by the corresponding number):
* A serial wire between the controling computer and the controled board (as CubieBoard here) and use the /dev/ttySx port.
* A standard USB< =>serial adapter/wire (as PL2303, CH340, FT2232C… compatible) and use then the /dev/ttyUSBx port.

Install Ubuntu-13.10 beta2 ARM on Cubieboard2 from another Cubie ARM system :)

Work in progress: Following this tutorial there is still problem with automatic network dhcp and clock at boot time, until installing a full distro desktop. I still need to find the needed packages to resolve this without installing the full distro

In my case, I start from a previously installed system with u-boot and kernel, this make things easier.
