BayLibre will attend the Vivatech Innovation and Technology Fair, June 15th through the 17th, in Paris, Porte des Expositions. Come join us, we look forward to meeting you and sharing with you.
Innovation and technology are at the heart of BayLibre. We pride ourselves on our expertise in low-level software development, open source software, and world-class embedded Linux and Android know-how. We apply these skills and knowledge to our client projects in IoT, camera, mobile, wearables, health, automotive and consumer electronics markets.
We could not miss the opportunity to go to this event that brings together other industry experts and game-changers like us. We hope to see you soon, do not hesitate to contact us, we will be happy to have a chat with you.

BayLibre is collaborating with Blocks as smartwatch developer.
At BayLibre, our engineers get to work on some of the most interesting technology in world. We’re equally lucky to get to work with some of the coolest companies on the planet.
BayLibre, Blocks smartwatch developer
Earlier this month Blocks announced that they are collaborating with BayLibre to develop embedded software for their forthcoming modular smart watch. We’ve been working with Blocks for quite a while and we’re thrilled to speak more about this engagement publicly!
While BayLibre has collaborated with Blocks on various parts of the embedded software stack, the part that has been talked about the most has been the port of Zephyr to the STM32L4 family of SoCs.
Blocks has been ultra-savvy about using Open Source software where it makes sense in their product, and as a result they will get to claim the honor of being the first CE device in the world to ship with Zephyr OS on board.
Without going into too much detail, Zephyr forms a critical part of the component responsible for managing the modular parts of the watch. The brain of the system remains Android-based as outlined in a Kickstarter update by Blocks.
We’re big fans of open source software, emerging technologies and cool products here at BayLibre. We’ve managed to work on all three while supporting Blocks as they move closer and closer to their ship date. We’re looking forward to seeing this seriously stylish wrist wear out in the wild!
The kernelci.org project aims to improve the quality of the mainline Linux kernel by improving testing and validation across the wide variety of diverse hardware platforms that run Linux.
There are so many different devices and platforms that run Linux, and Linux kernel development is moving so quickly that it is difficult to ensure that any given platform will remain working and stable with each Linux version. As an example, the chart here shows the growth in the number of 32-bit ARM based devices supported by Linux, with the total number of unique devices as of v4.11 just shy of 1400! That doesn’t even count the growing number of 64-bit ARM devices or any of the other architectures like x86 or MIPS.
With such an incredible range of supported hardware, how can the Linux kernel community continue to ensure that all of this hardware remains well supported and evolves with the rest of the Linux kernel?
The kernelci.org project set out to help solve that problem.
During the development cycle of the Linux kernel, whenever there are changes to the source-code repository, the kernel is built in a wide variety of configurations for several different architectures. Today, there are over 270 different build configurations across 4 architectures (x86, MIPS, ARM and ARM64.)
After a successful build, the kernel images are made available to the several distributed labs for testing. Due to the diversity of hardware that runs linux, no one lab is going to have all the hardware, so kernelci.org was designed for distributed testing. When builds are completed, each lab can download the images for the hardware available, and perform the testing. Currently there are 8 active labs contributing a total of more than 250 unique hardware platforms across 4 unique architectures.
BayLibre’s Kevin Hilman is a founding developer of the kernelci.org project, and today, BayLibre has the largest lab contributing results from over 80 unique boards across 25 unique SoC families and performing thousands of tests each day.
If you have hardware you’d like to see tested with the latest Linux kernel in the kernelci.org project, feel free to contact us. We can help guide you through setting up your own lab, or you could just send us your hardware and we can add it to our lab.
This particular demo was running the lastest Linux 4.10 release with some in-development patches for HDMI Support, Audio and Mali acceleration that will certainly go into the next Linux releases.
The AmLogic S905 embeds an ARM Mali-450 MP3 GPU running at 750MHz.
The technical showcase poster is available as PDF Version.

An excellent summary of this release can be found at KernelNewbies, and below is a summary of our contributions, organized by SoC family and a summary graph of contributions by developer. A special shout-out this development cycle goes to Neil Armstrong for the significant contributions of new DRM/KMS support for Amlogic SoCs.
A couple of weeks ago, we made public the ‘pyacmegraph’ tool that might interest you if you use our ACME probes for power management study or debug.
This tool handles ACME probes data capture and display, with some fancy features added.
Simply put, it’s an easy to use tool that aims at getting the best of ACME for studying a device power consumption.
In this post I will introduce pyacmegraph and explain how ACME is used to measure power and send this information to pyacmegraph. In a subsequent post, I will detail pyacmegraph features and functionning.
