AllWinner Announces A31s Processor for Phablets, Hints about Ubuntu Devices

AllWinner is currently a Mobile World Congress 2013, and Charbax had the chance to interview Eva, manager at AllWinner, and learn more about new processors, and future plans by the company. They spent some time discussing about AllWinner A31 and AllWinner A20 quad and dual Cortex A7 processors, but since we’ve know about those for a while I’ll skip this part. The most interesting part is about AllWinner A31s, a cost down version of A31, specifically designed for phablets (smartphones with 5″ to 7″ screens). Like AllWinner A31, AllWinner A31s is also a quad core Cortex A7 processor with PowerVR SGX544MP2 GPU (8 shader engines) and the following specifications: CPU – ARM Cortex-A7 Quad-Core with 256KB L1-Cache/1MB L2-Cache GPU – POWERVR SGX 544MP2 with 8 logic cores. OpenGL ES2.0, Open CL1.x and DX 9_3 compliant. Memory 32-bit Dual-Channel LPDDR2/DDR3/DDR3L Controller, 8-bit NAND FLASH Controller with 64-bit ECC Video UHD H.264 […]

Final Release of Fedora 18 for AllWinner A10 & A13 Powered Devices

A few months ago, Hans de Goede, currently working at Red Hat and a Fedora contributor, started to show up on linux-sunxi mailing list, and sent a lot of kernel patches for linux-sunxi kernel. Last week-end, he  announced “Fedora 18 Final for Allwinner A10 and A13 based devices” on linux-sunxi community mailing list. To install it, first download the image:

And write it to an SD card (all data will be wiped out):

You may have to replace “/dev/mmcblk0” by your own SD card device, e.g. “/dev/sdc”. AllWinner based devices can share the same kernel, but u-boot is board/products specific, so you’ll have to install u-boot for your board. First remove the SD card, re-insert it in order to automatically mount the FAT partition, and run:

This will show the list of supported boards and products. Then run the command again for your device. For example:

Open ARM GPU Drivers FOSDEM 2013 Video and Call to ARM Management

As I previously wrote, FOSDEM organizers are slowly uploading FOSDEM 2013 videos. One of the most interesting talk “Open ARM GPU Drivers” is now available. I’ve also uploaded it to YouTube (embedded below) to give it more exposure. Luc Verhaegen has also written a recent blog post entitled “Hey ARM!” where he announces the release of the modified source for Quake 3 Arena demo, and asks ARM to join them in making an open source driver. Open ARM GPU Drivers @ FOSDEM2013 This session covers the following key points: Problem – Binary drivers are mainly designed to run in Android, and it’s very difficult to have proper GPU drivers for Linux, and companies are not interested to release open source drivers or even just documentation, as they are not convinced it will benefit them in any way. Legal – This is actually the main issue, as open sourcing existing driver […]

Headless Connected Oscilloscope based on Cubieboard or Beaglebone

Warsaw ELHEP (Electronics for High Eenergy Physics Experiments) Group is currently working on MMS (Mobile Measurement System) Project. This project features what I would call a “headless connected oscilloscope”, which can be detected on the network via SSDP, send the data via Websocket, and display it on iOS, Android, or Windows Phone devices. This oscilloscope does not feature any screen, and receives/transmits data via Ethernet, Wi-Fi, or Bluetooth. The original hardware is based on three main boards: CTI-VMAX – ARM9 with Wi-Fi, Bluetooth, and Ethernet connectivity. ARM SCOPE v1.0.1 with  8 channel ADC. ARM SCOPE v1.0.2 with 4 high speed ADC (100MSPS). The ELHEP researchers have been looking at replacing CTI-VMAX with low cost boards, and after considering several options, they chose to design two versions of their oscilloscope: one based on Cubieboard, and the other on the Beaglebone. So they designed expansions boards for the Cubieboard and Beaglebone in […]

Quake 3 Arena Demo Using Lima Driver is (Slightly) Faster than Mali-400 Binary Driver

As mentioned previously, Luc Verhaegen was to give a talk about the status of Lima driver (reverse-engineered Mali-200/400 GPU driver), as well as other GPU open source implementation, at FOSDEM 2013. This is now done, and part of the talk included a demo of Quake 3 Arena (q3a timedemo) running on tablet featuring AllWinner A10 SoC (Cortex A8 @ 1Ghz, Mali-400MP1 GPU @ 320 Mhz, and DDR3 memory @ 360MHz), and a 1024×600 LCD. The fact it works is already a great achievement in itself, but this demo runs at 47.2fps with Lima driver (limare), whereas it can be rendered at 46.2fps using the binary driver. In his blog, Luc also explains that apart from being 2% faster, it also uses 3% less cpu than the binary driver! Take that binary blobs! There’s still more work to do however, as this Quake 3 Arena port is not playable yet for 2 […]

GPUs Comparison: ARM Mali vs Vivante GCxxx vs PowerVR SGX vs Nvidia Geforce ULP

I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge. There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. [Update: Two comments  mentioned Qualcomm Adreno and Broadcom VideoCore are missing from the list. Maybe I’ll do an update later]. Each company offers many different versions and flavors of their GPU as summarized below. ARM Imagination Technologies Vivante Nvidia Mali-400 Series: Mali-400 MP Mali-450 MP Mali-600 Series Mali-T604 Mali-T624 Mali-T628 Mali-T658 Mali-T678 PowerVR SGX Series 5: SGX520 SGX530 SGX531 SGX535 SGX540 SGX545 PowerVR SGX Series 5XT: SGX543MP1-16 SGX544MP1-16 SGX554MP1-16 PowerVR SGX Series 6: G6200 G6230 G6400 G6430 G6600 2D graphics: GC300 GC350 3D graphics: GC400 GC800 GC1000 GC2000 GC4000 ULP GeForce (Tegra […]

Smallart U-Host AllWinner A10 mini PC is Available for $20

Last July, I reviewed Smallart U-Host (U1A), an Android TV stick based on AllWinner A10 with 1GB RAM and 4GB RAM. At the time, I had a positive opinion of the device as the Android firmware was stable, and mostly did it was supposed, and it was feasible to run Linux distributions on the device. At that time, it was sold for $70, but this morning, Clint, one of my reader, informed me he spotted an AllWinner A10 device selling for $20.50 on Dealextreme. This device and the user interface resembles very much to Smallart U-Host, but the model name reported on Dealextreme is U2. According to Smallart U2 page, this device is based on Rockchip RK3066, so it’s just another naming mistake on DealExtreme. The rest of the specs are identical to Smallart U-Host: SoC – Allwinner A10 (Cortex A8) @ 1.5GHZ System Memory – 1GB DDR3 RAM Storage […]
