Linux 3.17 Released

Linus Torvalds announced the release of Linux Kernel 3.17 on Sunday: So the past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule (as opposed to the optimistic “maybe I can release it one week early” schedule that was not to be). However, I now have travel coming up – something I hoped to avoid when I was hoping for releasing early. Which means that while 3.17 is out, I’m not going to be merging stuff very actively next week, and the week after that is LinuxCon EU… What that means is that depending on how you want to see it, the 3.18 merge window will either be three weeks, or alternatively just have a rather slow start. I don’t mind getting pull requests starting now (in fact, I have a couple already pending in my inbox), but I likely won’t start processing […]

Cortus Introduces APS23 and APS25 32-Bit Cores for Micro-controllers

ARM and MIPS are not the only games in town with it comes to 32-bit cores for micro-controllers. I’ve already written about Beyond Semiconductor, and mentioned Andes used in some Wi-Fi SoC, and today I’ve come across another IP company called Cortus. which just introduced APS23 and APS25 cores based on their latest Cortus V2 instruction set. which offers a smaller code footprint compared to there V1 ISA. APS23 can achieve 1.44 Coremarks/MHz, 2.83 DMIPS/MHz, and can run up to 200 MHz when manufactured with 90nm process, whereas APS25 is a bit more powerful with 2.09 Coremarks/MHz, 2.36 DMIPS/MHz, and can run up to 344 MHz. Minimal power consumption is 11.6 and 19.3 uW/Mhz for APS23 and APS25 respectively. Key features of both cores include: APS23 APS25 Excellent Code Density 3 stage pipeline 5-7 Stage Pipeline Sequential Multiplier High Performance Integer Multiply Optional Parallel Multiplier (Gives 2.62 Coremakes/MHz) Integer Divider Full Peripheral Set Dual […]

How to Upgrade Allwinner A80 OptimusBoard Firmware

After informing Allwinner I had some rather slow write speed (3MB/s) to the NTFS partition of my USB drive on my A80 OptimusBoard, they kindly provided a new compressed Android firmware image (sun9iw1p1_android_optimus_v1.2_20140930.img.7z) with some NTFS optimizations that can be downloaded from baidu (password: x2tz), mega.co.nz or simos.info (please only use this link, if the other two do not work as it’s a private website and monthly bandwidth may be limited). I vaguely remember tools like LiveSuit (Linux) or PhoenixSuite (Windows), and I ended up on sunxi-linux Livesuit wiki as I’m running Ubuntu 14.04 on my PC, but you should be able to flash the firmware with PhoenixSuite if you run Windows. The instructions below can also be used for other Allwinner based devices. First you need to install LiveSuit, and build Allwinner USB drivers as follows:

sudo apt-get install dkms git build-essential
git clone https://github.com/linux-sunxi/sunxi-livesuite.git
cd sunxi-livesuite/awusb
make
sudo cp awusb.ko /lib/modules/`uname -r`/kernel/
sudo depmod -a
sudo modprobe awusb
cd..

sudo apt-get install dkms git build-essential

git clone https://github.com/linux-sunxi/sunxi-livesuite.git

cd sunxi-livesuite/awusb

make

sudo cp awusb.ko /lib/modules/`uname -r`/kernel/

sudo depmod -a

sudo modprobe awusb

cd..

In order to use LiveSuit as a normal user, you also have […]

Tronsmart T2000 EZCast Pro Dongle Supports MHL, Split Screen, Improves Wi-Fi Performance

EZCast dongles, tiny HDMI streaming Wi-Fi stick with support for Airplay, Miracast, DLNA, and their own proprietary EZCast protocol first appeared about a year ago. I’ve reviewed a few including Tronsmart T1000 and MeLeCast S1, and found them to work relatively well, with some caveats, in Android. There’s now a new EZCast Pro wireless adapters that adds features such for four split screens display, conference control via web browser, and content broadcast to multiple screens, as well as improved wireless performance thanks to 2T2R Wi-Fi. Tronsmart T2000 is the first device I’ve heard of, that’s EZCast Pro capable. Tronsmart T2000 hardware specifications: SoC – Action Semi AM8251 @ 500MHz (MIPS) System memory – 256 MB DDR3 RAM Storage – 128 MB NAND Flash Video output – HDMI 1.2 / MHL 2.0 Wi-Fi – Single band 802.11 a/b/g/n Wi-Fi 2T2R up to 300 Mbps Standards – Miracast, Airplay, DLNA, and EZCast […]
