Amlogic Releases Linux 3.14 Source Code for S905X, S905D, and S912 Processors, Has Started Working on Linux 4.4 / Android 7.0

Amlogic has just released buildroot with Linux 3.14 with support for Amlogic S905X (p212 board), S905D (p230 board), and S912 (Q200 board) processors, and the company appears to have started working on Linux 4.4 likely for future support for Android 7.0. You can check the source code as follows:

If you have the wrong toolchain the code won’t build (See comments section). So I installed several toolchains provided by Amlogic (all may not be needed) in /opt:

I also downloaded a shell script to add the toolchains to my path:

Once toolchains are setup, you can select one of three boards config (Q200 / S912 as example) and start building the code:

If you are interested in S905X or S905D instead, use respectively mesongxl_p212_release_defconfig or mesongxl_p230_release_defconfig. I built both S912:

and S905X images successfully:

Separately, you can also find buildroot for Linux 4.4, but […]

Boundary Devices Nitrogen7 Single Board Computer is Powered by NXP i.MX7 Processor

While several system-on-modules based on Freescale/NXP i.MX7 processor have been announced such as Compulab CL-SOM-iMX7, or TechNexion PICO-IMX7-EMMC, I had not seen many single board computers or development boards based on the new processor, apart from Freescale i.MX7 96Boards by Arrow Electronics which was scheduled for Q4 2015, but has yet to launch. Boundary Devices Nitrogen7 board is another option that’s available now (in limited quantities) with NXP i.MX7 Cortex A7+Cortex M4 processor, 1GB RAM, 4 to 64GB eMMC, wired and wireless connectivity, and expansion headers.

Next Thing Has Released Software and Hardware Files for the $9 CHIP Computer

Next Thing CHIP computer powered by Allwinner R8 module, also referred as “the $9 computer“, had a very successful crowdfunding campaign having raised over $2,000,000 from nearly 40,000 backers. When launching an electronics products on a crowdfunding campaign, many companies claim their device will be open source, only to disappoint once the perks actually ship, and Next Thing made the same promise, except they appear to have delivered as shown in their latest update “Holy C.H.I.P! It’s C.H.I.P!!!” showing the first production samples, and providing links to hardware design files for the Alpha version, as well as buildroot, U-boot and Linux source code. All resources can be found on docs.nexthing.co, but let’s check what they’ve released so far. Hardware design files on Github include: A Bill of Materials (BoM) Schematics in PDF and DSN formats PCB Layout in BRD and PNG format Pinouts for U12 and U14 connectors Mechanical files […]

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 […]
