MIPS Creator Ci40 Development Board Powered by cXT200 SoC Launched for $53 on Kickstarter

Last year, Imagination Technologies launched their first community development board with MIPS Creator CI20 powered by Ingenic JZ4780 dual core MIPS processor running both Android and Linux, and now supported by various projects. The company has been teasing about its MIPS Creatort Ci40 for a few weeks, and was already announced as the MIPS platform of choice for Google Brillo operating system, but the board has now officially been launched via a Kickstarter campaign where you can get the board for $53, as well as some add-on boards. But instead of using a processor from one of their partner, Imagination just designed their own MIPS interAptiv SoC for the board. Creator Ci40 board specifications: SoC – Imagination Technologies Creator cXT200 with 2x MIPS interAptiv core @ 550MHz, 512KB L2 cache, and an Ensigma C4500 RPU (for 802.11ac/ BT 4.1 LE) System Memory – 256 MB DDR3 Storage – 512 MB […]

How to Build Brillo Operating System from Source Code and Run Brillo Emulator

Google formally launched Brillo operating system a few weeks ago. The new operating system is a stripped down version of Android that targets Internet of Things (IoT) applications, and more recently the company pushed the source code to their servers. So I’ve given it a try by checking out the code, building Brillo emulator for Intel/AMD, and running it in Ubuntu 14.04 64-bit. First you’ll need to retrieve the source code:

mkdir brillo-master
cd brillo-master
repo init -u https://android.googlesource.com/brillo/manifest -b master
repo sync -j8

mkdir brillo-master

cd brillo-master

repo init -u https://android.googlesource.com/brillo/manifest -b master

repo sync -j8

It took a few hours here with some errors the first time, so I tried again and I finally got the code a few hours later. Once this is done, set the build environment and configuration:

source build/envsetup.sh && lunch

1	source build/envsetup.sh && lunch

Lunch will bring a list of possible builds:

You could also run the “Brillo emulator” on ARM, and edison-eng must be the build for Intel Edison board. Now you can start the build:

DragonBoard 410c Development Board Quick Start Guide and Android Benchmarks

Linaro’s 96Boards initiative was announced in February with the introduction of Hikey board, and while progress has been rather slow, there are now two boards available for sale: Lemaker Hikey and Qualcomm Dragonboard 410c. The main advantage of these board is that 96Boards is not only an hardware specification, but also a software specifications that mandate most code to be open source, with recent versions of Linux and U-boot, and in the case of Dragonboard 410c work is being done with Freedreno open source GPU drivers. Now that I’ve got a board I’ll explain my experience with the purchasing process, take a few pictures, and show how to get started with Android, and install the latest version, before running a few benchmarks. Ordering DragonBoard 410c Development Board I normally don’t like purchasing from North American and European distributors, because of the potential documentation involved to comply with silly laws, high […]

GeekBox is a Hackable Android and Linux TV Box Powered by Rockchip RK3368 SoC

There are many Android TV boxes on the market based on Rockchip RK3368 processor, while I’m not aware of any development board based on the latest Rockchip octa-core processor, and Linux support is basically inexistent. One device may fill both gaps: GeekBox. This TV box can run both Android and Ubuntu Linux, while it’s easily disassembled to access expansion headers. The hardware specifications are a little higher-end than most Rockchip RK3368 TV boxes we’ve seen so far: SoC – Rockchip RK3368 octa core Cortex A53 processor @ 1.2 GHz with PowerVR G6110 GPU System Memory – 2GB LPDDR3@1600Mbps Storage – 16GB Samsung eMMC v5.0 flash + micro SD slot Video Output / Display I/F HDMI 2.0 up to 4K @ 60Hz with CEC support Display + touchscreen headers Audio Output – HDMI Connectivity – Gigabit Ethernet, 802.11 a/b/g/n + 802.11ac 2×2 MIMO @ 867 Mbps (AP6354 module), Bluetooth 4.1 USB […]

Amlogic S905 Source Code Published – Linux, U-Boot, Mali-450 GPU and Other Drivers

Amlogic has an open linux website where they regurlarly release GPL source code, and with Amlogic S905 devices coming to market, they’ve released a few tarballs at the beginning of the month including Linux 3.14 source code, U-boot source code, and Mali-450MP GPU kernel source code (obviously not userspace), as well as some other drivers for WiFi, NAND flash, PMU, TVIN, etc… Let’s get to the download links: Linux 3.14.29 source code U-boot 2015.01 GPU drivers for ARM Mali-450MP Broadcom and Realtek Wifi drivers and firmware (November 4, 2015) can be found @ http://openlinux.amlogic.com:8000/download/ARM/wifi/. Other kernel modules (November 4, 2015) @ http://openlinux.amlogic.com:8000/download/ARM/modules/. I quickly tried to build the Linux source. If you’ve never build a 64-bit ARM kernel or app before, you’ll fist need to install the toolchain. I installed the one provided with Ubuntu 14.04:

sudo apt-get install gcc-aarch64-linux-gnu

1	sudo apt-get install gcc-aarch64-linux-gnu

Now extract the tarball and enter the source directory:

tar xvf arm-src-kernel-2015-11-04-9e845bea41.tar.gz 
cd arm-src-kernel-2015-11-04-9e845bea41
