Kernel Recipes: Mainline Linux on AML-S905X-CC: Le Potato

At Kernel Recipes this year, BayLibre was proud to partner with the Libre Computer Project to give away around 30 “Le Potato” boards to attendees.  Kernel Recipes is already known for its throw microphone, but this year each speaker threw a “Le Potato” board at the audience.

For those who received the board, pre-built images (to be written to a microSD card, at least 4Gb) are available here :

What works:

BayLibre’s team experts talk in the Open source community

It’s the end of holidays and we’re ready to tackle September in fine fettle.
Two major conferences are taking place in the Embedded and Open source community.
BayLibre is sponsors at those events.
We are longing for them for good reasons!

Two Jedi of our team, will demonstrate their power as embedded systems experts.

  • Neil Armstrong (yes the real one !) : Embedded system expert and software engineer, one of the Embedded Recipes speakers
  • Kevin Hilman : Linux Kernel expert, one of the Kernel Recipes speakers

Embedded Recipes

The first edition of the Embedded Recipes conference, #er2017, will take place in Paris, the 26th of September 2017.

Just as it’s big sister, Kernel Recipes, the objective is to bring together a developer community.

That day will be dedicated to Embedded Open Source actors.

Share your experience with us.

We wish a happy 6th edition to Kernel Recipes!

From the 27th to the 29th September 2017 in Paris.

A great, human and professional experience as always.

A unique track of conferences on subjects as varied as:

  • Open source hardware,
  • Core,
  • Security,
  • Experience feedback,
  • Industrialization processes
  • and so many more…

Blocks + BayLibre smartwatch developer

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!
