Free Electrons Releases Buildroot Training Materials

Free Electrons develops embedded Linux & Android software, and also provides related training. On-site training sessions are scheduled from time to time, or organized on request, and they usually release their training materials for free, as they did for their Embedded Linux training in 2012, or their Yocto Project / OpenEmbedded course more recently. Thomas Petazzoni, Free Electrons’ Chief Technical Officer, recently informed me that the company also released training materials for Buildroot, which like the Yocto Project is a build system, but it had been around for much longer, and the company is actively participating in its development with over 2,800 patches submitted upstream over the years. Four main resources have been released for the course, under a Creative Commons BY-SA license: training materials for Buildroot – 325 pages Practical labs instructions (PDF) with BeagleBone Black – 32 pages Practical labs data (.tar.xz) – Patchsets for drivers, rootfs, and […]

Calao Systems Introduces Linux based DIN Rail Home and Building Automation Systems

Calao Systems is an embedded systems company that I came to know thanks to their Snowball development boards based on the now defunct ST Ericsson Nova A9500 processor. The company has now launched new products for building and home automation powered by Atmel AT91SAM9G20 ARM9 processor clocked at 400 MHz housed in a DIN Rail enclosure. Two products are now available HABA-KNX-EXPLORER and HABA-KNX-LITE that share the following specifications: Processor – Atmel ARM926EJ-S @ 400MHz System Memory – 128MB SDRAM Storage – 256MB NAND Flash, 16 Mbit serial flash, 2Kbit EEPROM with MAC address, and Micro SD slot Connectivity Lite – 1x Ethernet 10/100Mbits Explorer – 2x Ethernet 10/100Mbits USB –  2x USB Host FS (12Mbits), 1x USB Device FS (12Mbits) Serial (Explorer only) – 1x RS-232 (isolated), 2x RS-485 (isolated) Automation I/F – 1x KNX/TP1 (isolated) Expansion – 1x RF Expansion Connector Debugging – JTAG and DBGU interfaces Misc […]

Emtrion SBC-SAMA5D36 ARM Cortex A5 Linux Development Board Comes with Dual Ethernet, HDMI Output

A few months ago, I reviewed Atmel Xplained SAMA5D3 development board powered by SAMA5D36 Cortex A5 processor. The kit is supported by the Yocto Project, so I could build and run Poky distribution with a recent Linux kernel (it support mainline), it features Arduino compatible headers, and I found the board to be a nice platform for headless applications, or applications that require an LCD display. However, if you wanted to connect an HDMI display you’d be out of luck, unless you design your own LCD to HDMI add-on board. Emtrion SBC-SAMA5D36 could be an interesting alternative, as it features very similar specifications, but adds an HDMI output port. Emtrion SBC-SAMA5D36 specifications: MPU – Atmel SAMA5D36 single core Cortex-A5 @  536 MHz System Memory – 256 MB RAM Storage – 512 MB NAND Flash, up to 16 MB NOR Flash, and micro SD Card socket Connectivity – 100Base-TX Ethernet,  10/100/1000Base-TX […]

AllWinner A80 Linux SDK Released

After Android 4.4 SDK for AllWinner A31 last week, another AllWinner software development kit has been seen in the wild, this time for the new AllWinner A80 octa-core processor. A80 SDK includes source code for the Linux Kernel and U-boot, as well as buildroot, and various AllWinner tools. I’ve also noticed AllWinner A80 datasheet is available, but with the strict minimum information (45 pages). Let’s get the code, and extract it:

Now we need to configure the build:

sun9i is the codename for AllWinner A80, not sure what w1p1 means. Dragonboard must be the internal Allwinner development board, but I just selected Linux, since the SDK does not come with Android, and finally I opted for optimus, which could stand for OptimusBoard. You may need to install extra dependencies in your build machine, for example (in Ubuntu 14.04):

Now let’s start buildroot which should retrieve the toolchain, […]

Wandboard Dual Benchmarks, Serial Console Fun, and Distributions List

Since last time I tried Android and Ubuntu on the Wandboard, a few things happened. I’m not talking about Wandboard Quad announcement, but instead I received a Class 10 SD card, which makes the system so much responsive, and a RS232 to USB adapter so that I can access the serial console. So today, I’ll publish some benchmark results on Wandboard Dual since none appear to be available, and play a little with the serial console. A few things also happened on the operating systems side with more distributions now available for the board. Prerequisites I ran benchmark in Android, so I installed the latest Android 4.1.2 image (11th of April 2012) to my new SD card (ADATA 16 GB Class 10), and contrary to my poor experience on a 4GB Class 4 micro SD, everything was very fluid. I’ve also installed Google Play in order to install the applications. […]
