Bootlin's founder and engineer Michael Opdenacker will give an introduction to Embedded Linux next week at the free Live Embedded Event. In 45 minutes, you will discover how to build your own embedded Linux system completely from scratch, and the RiscV architecture too. Details on frama.link/eDVxqWFT

Bootlin engineer Miquèl Raynal, who is also the Linux kernel MTD subsystem co-maintainer, has recently worked on rewriting and upstreaming the Linux kernel driver for the NAND controller found on Xilinx Zynq platforms.

As part of this work, supporting this NAND controller ECC engine turned out to be quite challenging, and Miquèl reports in our latest blog post at bootlin.com/blog/supporting-a- about those challenges

Overall, the Xilinx Zynq NAND controller driver is now upstream in the Linux kernel !

News dates for our "Displaying and rendering graphics with Linux" online course, taught by our graphics and video expert Paul Kocialkowski: September 22 to 25, 2020.

We have a new blog post from Alexandre Belloni : how to configure ALSA controls from your user-space application, with a clean C API provided by alsa-lib. See bootlin.com/blog/configuring-a to learn how to do this without invoking amixer/alsamixer.

Bootlin engineer Miquèl Raynal submitted to the Linux I3C community a new driver for an I3C Master Controller: the Silvaco I3C Master Controller IP. See the main patch from Miquèl at lists.infradead.org/pipermail/, which adds the driver itself.

Note that Bootlin pioneered the support of I3C in Linux, as we contributed the core I3C subsystem a few years ago. See our blog posts at bootlin.com/blog/i3c-subsystem and bootlin.com/blog/i3c-upstream-

Study embedded Linux without hardware by using our freely available lectures and practical labs on the QEMU emulated ARM Vexpress Cortex A9 board. Except for nand flash and realtime, all features are available: toolchains, U-Boot, tftp, Linux kernel, NFS booting, MMC/SD, SquashFS, cross-compiling, Buildroot, application development and debugging with strace, ltrace and gdb.

Materials available on: frama.link/_C6dxaQ1

Get support by attending our next online session: frama.link/x2P0mkxV

New dates announced in the end of July, beginning of August for Bootlin's online embedded Linux course (with optional labs on QEMU ARM), at a time suitable for our customers in the Americas. More details on eventbrite.com/e/bootlin-embed

Did you know?
You can use the Elixir Cross Referencer to look up kernel configuration settings in defconfig files.
See by yourself in elixir.bootlin.com/linux/lates for example.

v2.1 of the Elixir Cross Referencer also adds support for Device Tree compatible strings. When browsing Device Tree files, you can instantly find matching drivers, Device Tree bindings and other Device Tree files using the same compatible string.

Thanks to Maxime Chrétien again!

Example: elixir.bootlin.com/linux/lates

Elixir Cross Referencer v2.1 features symbol search autocompletion, contributed by Maxime Chrétien. This makes it easy to find Linux kernel function names while programming!

Tomorrow, Bootlin's
engineer Paul Kocialkowski, who has worked on Allwinner video decoding, and author of our Linux graphics course will teach our first online edition of this course! You want to learn everything about the Linux graphics stack?

We modified the timing of our next online Linux kernel course to fit the constraints of our US customers: from 8:00 AM to 12:00 PM (San Francisco time)

This corresponds to 5:00 PM to 9:00 PM (Paris time), which can also work for people taking the course outside of working hours.

The dates are July 6, 7, 8, 9, 10, 15 and 17, 2020.

If this offering meets customer demand, we will be happy to extend to it our other online courses 😉

In the next online session of our Embedded Linux course, we will propose QEMU ARM instructions for most practical labs before showing solutions on real hardware.

Such labs will be optional and will be proposed between each half day session.

See our detailed agenda on frama.link/qVtVxQvU

Practising by yourself will definitely help with learning.

Our June online Buildroot training course with Buildroot's
co-maintainer Thomas Petazzoni is now completed, so we've opened a new session on July 28-31, 9 AM to 1 PM UTC+2 on each day. Register at frama.link/PRWH0Mjj and get trained on using Buildroot with an expert!

Our online Yocto Project / OpenEmbedded training course starting tomorrow with Alexandre Belloni as instructor is full! So we've opened a new session for this course: July 28-31, 9:00 AM to 1:00 PM UTC+2 each day. Register at frama.link/Pz6GAJ-s

elixir.bootlin.com has become a time machine!
It now allows to explore the code of most Linux releases since the beginning (except a few that were apparently lost). Thanks to Arnd Bergmann for the suggestion!

elixir.bootlin.com is up with many new features from the latest v2.0 release: support for function documentation, Kconfig symbols, Device Tree aliases, function documentation, REST API...

Checkout our blog post covering all these new features: bootlin.com/blog/new-feature-h

At Bootlin, the tradition is to share all the evaluations from the participants to our training sessions, and not just keep the good ones : bootlin.com/training/ratings/

So, here are the evaluations from our first public online Embedded Linux course: bootlin.com/feedback/training/

Given the demand for our online courses, we're opening a new Linux kernel driver development session between June 8 and 16. All details are on bootlin.com/training/kernel/

The trainer will be Michael Opdenacker, Bootlin's founder.
