Preliminary Reverse-Engineered VPU Driver (CedarX) for AllWinner A10 Plays H.264 Videos

Allwinner framework for their Video Processing Unit (VPU) in their Cortex A8 processors (A10, A13, etc..) is called CedarX. It relies on a binary blob that is working just fine for Android, but not so well for Linux. So several developers started to reverse-engineer CedarX a while back, to fix issues with Linux, and provide an open source driver. Yesterday, they upload a video to show the development progress, and show Big Buck Bunny 1080p H.264 playback using libvdpau-sunxi open source driver with mplayer, and without any binary blobs.  The video resize function are not been implemented yet, which is why we can only see the left corner of video, but nevertheless it shows an open source hardware video decoder is on the way. That means once the Lima driver for Mali-400 GPU, and libvdpau-sunxi driver for AllWinner VPU are implemented (which may still take a while), AllWinner A10 SoC […]

Fedora 19 ARM Remix R1 Release With Support for AllWinner A10, A10s, A13 and A20 SoCs

After releasing a stable version of Fedora 18 for AllWinner A10 and A13 in February, Hans de Goede, working at Red Hat and a Fedora contributor, has recently announced “Fedora 19 ARM remix for Allwinner SOCs” on linux-sunxi community mailing list. This released based on Fedora 19 for ARM together with linux-sunxi kernel and u-boot, adds support for A10s and A20 based devices, and 38 boards and devices are now supported. To give it a try, download the 665MB image:

then write it to an SD card (8GB or greater):

Where you have to replace [device] with your actual SD card device, e.g. sdc.Since u-boot is board/product specific, you’ll also have to update u-boot for your hardware. Remove the SD card, re-insert it, and run:<

Rockchip RK3066 is Now Part of Mainline Linux Kernel

After AllWinner A10/A13 SoCs, it’s time for another Chinese SoC to be included into mainline kernel, with Rockchip RK3066(a). A few hours ago, Heiko Stuebner’s commit for basic support in Linux kernel 3.11 has been accepted. This is the commit message: This adds a generic devicetree board file and a dtsi for boards based on the RK3066a SoCs from Rockchip. Apart from the generic parts (gic, clocks, pinctrl) the only components currently supported are the timers, uarts and mmc ports (all DesignWare- based). Don’t get too excited though, as it may take a little while until you can actually build a kernel for Rockchip RK3066 or AllWinner A10 from mainline linux source code. But this is definitely another step in the right direction, and hopefully, Chinese SoC companies will eventually get involved, instead of relying on the community, as it is in their best interest. To access the full list […]

How-to Upgrade Firmware on AllWinner A31 mini PCs

I’ve just received a mini PC powered by AllWinner A31, and I had to (re-)install the firmware, so I’ll explain the steps I followed in this post. The procedure is for CS868 mini PC, but it should be similar for all Android HDMI TV dongles, and media players based on AllWinner A20 or A31.The procedure below only works in Windows, and has been tested in Windows XP. I’ll mention a possible method in Linux at the end of the post. Download the latest CS868 firmware and tools, and extract “cs868 firmware and update tool 20130507.rar” file Download PhoenixUSBPro tool in English, and extract This is optional as the Chinese version is included in rar file above. Double-click on PhoenixUSBPro/PhoenixUSBPro.exe to start the program Click on Update to upgrade the tool to the latest version if need be. Click on Key to to load the key file (AW_LCTOOLS.key), on Image to […]

Posted on by Jean-Luc Aufranc (CNXSoft) - 3 Comments on N70-A and N70-B AllWinner A20 and A31 Based Android Netbooks with 13.3″ Display

N70-A and N70-B AllWinner A20 and A31 Based Android Netbooks with 13.3″ Display

Last year, H6 Android Netbook featured AllWinner A10 Cortex A8 processor, 1GB RAM, 4GB Flash, and came with a 10.1″ display with 1024×600 resolution, and people who tried did not seem very satisfied with their purchase. This year however, we should get more better hardware thanks to devices like N70-A and N70-B, respectively powered by AllWinner A20 with 1GB RAM, and AllWinner A31 with 2GB RAM, that both come with a 13.3″ display (1280×800). There’s also N101-A model powered by AllWinner A20, but it comes with a 10.1″ display with 1024×600 resolution.  All models are available with 8, 16 or 32GB flash, feature Wi-Fi 802.11n and Ethernet connectivity, a 0.3MP front camera, an SD card reader, 2 USB ports, 1 HDMI output, as well as mic IN and headphone jacks. For some reasons, AllWinner A20 models runs Android 4.2.2, but AllWinner A31 still runs Android 4.1.2. You should be able […]

Charbax is now at the China Sourcing Fair in Hong Kong, meeting and interviewing lots of Chinese companies. One of the companies I’ve been following is AllWinner because of their low-cost ARM Cortex processors, found in many Android devices, which somewhat support Linux. In the video below, we first learn they have shipped 1 million A31 in the last 4 months, A31s and A20 processors have been available since the end of March for phablets, and A20 price is supposed to be very close to A10. So products based on AllWinner A10 could be upgraded to AllWinner A20 for just a few dollars more as both SoC are (nearly) pin to pin compatible. By the way, if you’re interested in the Cubieboard, you may want to see this. We then go through lots of devices based on AllWinner SoC, albeit too fast to get many details, but the list may […]

AllWinner A20 Linux Source Code, EVB Schematics and Product Brief

Hardware based on AllWinner A20 such as Cloudsto Media PC PRO DRIVEDOCK, should start to be available soon, and resources for developers have been slowly released (or leaked) to the community. AllWinner A20 Source Code The source code for AllWinner A20 and A31 has been released to sunxi-linux a while back, and they have started to clean up the code before hardware becomes available. The code apparently hasn’t made it to sunxi-linux github account just yet, but Linux for A20  has been imported into github at https://github.com/amery/linux-allwinner/tree/import/lichee-3.3/a20-dev. AllWinner A20 is known as sun7i in the code. AllWinner A20 Evaluation Board Schematics and Product Brief Olimex received A20 EVB schematics and product brief from AllWinner earlier this week, and as usual, they promptly uploaded those documents to their github account. The 3-page product brief does not bring anything new, and the data sheet does not seem to be available right now. […]
