Nexbox A1 serial console

The Nexbox A1 which includes an 8-core Amlogic S912 processor, is now supported in v4.10 of the Linux kernel, thanks in part to the work of BayLibre.

If you’d like to help with kernel development on this platform, the first think you’ll need is access to the serial console.  The serial port is not brought out to a connector, but pads are easily accessible on the main board.Nexbox A1 UART pins

Once you open the case, you’ll pads for the UART signals between the heat sink and the edge of the board.

In the photo to the right, wires have been soldered to the pads:

  • Red: VCC
  • Orange: RX
  • Yellow: TX
  • Black: Ground

Hooking the newly soldered wires up to a USB serial cable such as this one, you’ll see the boot-loader and linux kernel messages on your as soon as you power on the board.

Now you’ll be ready to dive in and help with kernel development on Amlogic processors.   Enjoy!

Kernel Recipes 2016

kr-khilman-1
BayLibre was proud to be a sponsor of this this years Kernel Recipes conference in Paris.  Kernel Recipes is a small, technical conference focused on various topics related to the Linux Kernel.

kr-crowdI was a speaker again this year, and  gave a talk about the kernelci.org project.  The talk was a brief overview of the project, its history and ways to contribute.   Slides available here and video recordings will be available soon.

One of the fun parts of Kernel Recipes was all the speakers and some lucky audience members got caricatures of them drawn by artist Frank Tizzoni.  Here is one of me and one of the crowd, with a bunch more available on Kernel Recipes Twitter feed.

 

BayLibre contributes to kernelci.org

The BayLibre Lab is online and test results are being contributed to the kernelci.org project. In addition to standard boot tests, BayLibre is
developing a power regression test suite using LAVA and the kernelci.org infrastructure. We can’t wait to push the state of the art forward
around automated testing and quality assurance for Linux.
Marc has led the effort to bring the BayLibre Lab online. He has been supported by Kevin, Tyler, Neil and Milo from Linaro who patiently answered all of our questions about setting up the LAVA environment and integrating it with the kernelci.org project. Thanks again everyone.

Our first results are available here : http://kernelci.org/boot/all/lab/lab-baylibre/
