Hi all, I've got 3 pcs. Cubieboard 2 SBC's with the Allwinner A20 SOC Chip on them. That's kind of a RaspberryPi SBC with an 2 Code Arm7hf on it. The boards are equipped with HDMI, USB, Ethernet (100Tx), SATA, SD Card slot and some 4G NAND Flash Cip on it. RAM is 1 Gbyte, CPU Clock is 996Mhz.
Additionally I've bought some Base Boards for them, that's the DVK521 from Waveshare..contains the Baseboard, an Camera Module OV670, a 7" LCD with LVDS, a thermo sensor and other things.. Good HW in my eyes, but already outdated. I wnt to use the boards for some Home/house related stuff, PV, heating, Light control etc. and for that they should be more than enough. The Chips even have an graphics accelerator in the SOC. Now the Problem: as far as I know Allwinner has made some mistake using gnu/Linux stuff without any respecting the GPL. Because of that (if no other cause) most of the support Software on the net seems to be gone. There where some different Linux distributions for it, (Linaro, Cubieez etc) but most of the stuff isn't available anymore because of dead links. I've successfully build an modern Armbian image for them..but have endless trouble. The Xserver configutres an not existing Video Output, the LCD is unknown at all and if I manage to switch the X-server to the HDMI output using xrandr (only with tricks because it needs a session) the performance is like some old thick glue... Besides of that I had to fix an already for 8 years known Bug in the A20 Ethernet driver (it simpy has a more modern ethernet Unit as the A10 inside) that was'nt fixed at all. Armbian has only "community Support" fo those chips..which means that there is no support at all. If one asks for help the answer is more or less "find it yourself and provide a patch". I have an Linaro disk image that seems to be working, but there are some parts missing. The base distribution seems to be ubuntu 12.04 LTS (precise Pangolin) for armhf. I can't find a package repository anymore..(since that's long outdated). I've managed to install ssh by using an tarball of an ubuntu 12.04 armhf image for another board..and it works..but sshd is still missing. There are more modern disk images at https://mega.nz/folder/ZtwxCCJC#AIYHcTqz-ucjuzKnE9qD7A/folder/t0p2SBQD but mostly they don't even boot..possibly they using an newer/other uboot and uboot-envirnonment... Now the question: Is someone in the world still using those boards and has disk images/software for them? Again: I'ts not that much interesting that this is old linux, because I'll use that only inhouse in the lan, not browsing actual websites.. I'm a BSD guy and not know that much about Linux, especially such things as configurations for uboot etc. and there is none that I could ask for such things. Kind Regards, Holm -- Technik Service u.
