Check GitHub profileUEFI/EDK II CorebootPayloadPkg on PC Engines apu2
Published at November 3, 2017 · 9 min read
Recently we were reached by person interested in running CoreOS on apu2. CoreOS is a very interesting system from security point of view. It was created to support containers and scalability out of the box. Unfortunately it requires firmware supporting GPT. At that point I was not sure if I can utilize GRUB GPT support on apu2, but this led to other questions: Is it possible to boot UEFI-aware OS on PC Engines apux boards?...

PC Engines apu2 python Robot Framework validation automation
Published at November 2, 2017 · 8 min read
Recently we attended ECC2017 conference. One of topics that we considered was a system for development and validation automation. Unfortunately this talk was not accepted, but we present some research below and plan to provide more soon. As maintainers of PC Engines platforms in coreboot we debug and fix quite a lot of bugs, but to take full responsibility for our code everything should be validated each time we do release....

OpenOCD and development environment for Zephyr on NXP FRDM-K64F
Published at March 18, 2017 · 12 min read
In this post I would like to describe process of setting up NXP FRDM-K64F development environment under Linux and start Zephyr development using it. Why NXP FRDM-K64F ? I choose this platform mostly because of ready to use guide about using 802.15.4 communication by attaching TI CC2520, which was presented here. Typical wireless stack starts with 802.15.4, then 6LoWPAN adaptation and then IPv6, which carries application protocols. 6LoWPAN compress IPv6 so it can fit BLE and 802....
Nerves project triage on BeagleBone Black
Published at March 10, 2017 · 6 min read
Recently one of my customers brought to my attention Nerves. It aims to simplify use of Elixir (functional language leveraging Erlang VM) in embedded systems. This system has couple interesting features that are worth of research and blog post. First is booting directly to application which is running in BEAM (Erlang VM). Nerves project replace systemd process with programming language virtual machine running application code. Concept is very interesting and I wonder if someone tried to use that with other VMs ie....
Zephyr initial triage on Nucleo-64 STM32F411RE
Published at January 14, 2017 · 7 min read
As I mention in previous post Zephyr RTOS is an interesting initiative started by Intel, NXP and couple other strong organizations. With so well founded background future for this RTOS should look bright and I think it will quickly became important player on IoT arena. Because of that it is worth to dig little bit deeper in this RTOS and see what problems we faced when trying to develop for some well known development board....
Failure of ECC508A crypto coprocessor initial triage with SAM G55 Xplained Pro Evaluation Kit
Published at November 24, 2016 · 7 min read
Some time ago (around August 2016) embedded community media were hit with hype around simplified flow for AWS IoT provisioning (1, 2, 3). I’m personally very interested in all categories related to those news: IoT - is 3mdeb business core and despite this term was largely abused these days, we just love to build connected embedded devices. Building this kind of devices is inherently related with firmware deployment, provisioning and update problems....
Starting with Nucleo-F411RE and mbed OS for command line enthusiasts
Published at November 23, 2016 · 9 min read
When I first time read about mbed OS I was really sceptical, especially idea of having web browser as my IDE and compiler in the cloud seems to be very scary to me. ARM engineers proved to provide high quality products, but this was not enough to me. Then I heard very good words about mbed OS IDE from Jack Ganssle, this was still not enough. Finally customers started to ask about this RTOS and I had to look deeper....
Chromium GStreamer backed for i.MX6 research
Published at November 1, 2016 · 3 min read
Recently I work on i.MX6 based project that requires video hardware decoding in web browser (best case in QtWebEngine, which is entire Chromium platform in Qt). Chromium After some research it appears that Chromium is not interested in providing external support for GStreamer-backed video hardware decoding. Truly going through all discussion related to this topic was very dissapointing. Typically Chromium developers just close thread when discussion started to be noisy and there mass of complaining people raised....
