Rockchip RK3188 Linux Source Code is Now Available

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs. Let’s have a look:

[Update: you may have to run “sudo apt-get install libc6-i386” before running make_kernel_ruikemei.sh below, as mkkrnlimg is a 32-bit binary] Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

After just over a minute, success!:

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188. Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs: rk3168_86v_defconfig rk3188_dongle_defconfig rk3188_ds1006h_defconfig rk3188_ds1006h_v1_0_defconfig rk3188_hotdog_defconfig rk3188_LR097_defconfig rk3188_magicwand_defconfig […]

Calxeda Showcases Aaeon and Foxconn ARM Servers at Computex 2013

ARM started to get involved in servers in 2011 with the announcements of Calxeda Energy Core, Marvell, and Applied Micro X-Gene Servers-on-a-Chip, and in 2012, products made by companies such as HP and Mitac  started to appears. We’ve got to see some more ARM based servers this year thanks to Charbax, who filmed some Aaeon and Foxconn servers powered by Calxeda EnergyCore quad core ARM Cortex A9 SoC at Computex 2013. The first server is Aaeon Indus 1U cloud storage appliance: 1U Chassis 2x Calxeda Energycore nodes 10x 3.5″ HDD 2x 10 GbE uplinks and 4x 10GbE chassis-to-chassis interconnects Foxconn server shown at Computex has slightly higher specs: 4U chassis 12 Calxeda Energycore nodes 60x 3.5″ HDD for up to 240TB storage 4x 10 GbE uplinks and 6x 10 GbE chassis-to-chassis interconnects for 100 GbE total bandwidth There’s also a Gigabyte server, but I could get details.

Meet DAXIAN XY100S, a $100 Quad Core Android Smartphone

Last year, I wrote about a $50 Android smartphone, and yes, it was cheap but the specifications were pretty poor. But today, I’ve just learned about DAXIAN XY100S powered by Mediatek MT6589 quad core Cortex A7, with a 4.7″ display, and running Android 4.2, which just sells for under $100 on Buyincoins.com, including shipping. That’s about $50 cheaper than the cheapest MT6589 models I found. DAXIAN XY100S specifications as listed on buyincoins: Operating System: Google Android 4.2 SoC – Mediatek MTK6589 quad core Cortex A7 @ 1.5GHz + PowerVR SGX544 GPU System Memory – 1GB RAM Storage – 4GB NAND Flash + micro SD card slot (Up to 32GB) Display – 4.7″ Multi-touch Capacitive screen (854 x 480) Network – GSM: 900/ 1800 MHz, 2010-2025 MHz / 1880-1900 MHz (Dual SIM), 3G: TD-SCDMA Connectivity – Wi-Fi 802.11a/b/g/n Camera – 2.0 MP front camera, 8.0MP rear camera USB – 1x micro […]

Bluetooth Versions Walkthrough, and Bluetooth 4.0 Low Energy Development Resources

I’ve seen more and more Bluetooth 4.0 LE devices in the last few months including RFDuino, Wimoto Motes, TI SensorTag, and Scadanu Scout, so I thought it would be good to write a bit about Bluetooth. First, I’ll write about the different version of Bluetooth, since I was still confused with the practical implications between the versions, and then I’ll show some development kits and software resources to play around and/or develop Bluetooth 4.0 LE applications both on devices and hosts. Bluetooth Versions Bluetooth v1.0 and v1.0B The Bluetooth 1.0 Specification was released in 1999, and according to an entry in Wikipedia, 1.0 and 1.0B devices had many issues, mainly interoperability issues. You won’t find any Bluetooth 1.0 device today. Bluetooth v1.1 Bluetooth v1.1 was ratified as IEEE Standard 802.15.1-2002 in 2002. It fixed many issues found in the previous specifications, added the option to use non-encrypted channels, as well […]

Scanadu Scout Medical Tricorder for Android and iOS

Low cost personal medical tricorders have the potential to dramatically bring down the cost of health care, and avoid unnecessarily wasted time in hospitals, which is probably the XPRIZE Foundation has launched a competition for  medical tricorders, where the winners will get 10 millions US dollars in funding. Scanadu Scout is one of the entry, and they currently have an indiegogo campaign, already oversubscribed, for their medical grade tricorder which gather data by placing it on your forehead for 10 seconds, and display medical data transferred via Bluetopoth Low Energy (Bluetooth SMART) on your iOS and smartphone. The company did not disclose full specifications, but they still revealed the device runs 32-bit Micrium RTOS, which is already FDA approved (pre-market 510K notification and PMA approval), it supports Bluetooth 4.0 SMART, and a micro USB port is included to recharge the battery. I fired up few Google image searches to look […]
