Linux microPlatform, secure IoT updates with Foundries.io and Toradex
Posted by – October 13, 2018
Category: Internet of Things, Development Boards, Exclusive videos, Nvidia, NXP, Linaro Connect, Toradex, Foundries.io
At Linaro Connect Vancouver 2018, Foundries.io and Toradex discuss Linux microPlatform, what microPlatform is and how it helps Toradex to build their next generation Software Platform.
Linux microPlatform is an open source, minimal, secure, updatable Operating System based on OpenEmbedded / Yocto Project. Toradex ports the microPlatform to its Arm-based System on Modules and it uses it as the basis for its future Software Planform called Torizon.
Linux microPlatform modularized the embedded software stack utilizing Docker Containers, and so it provides a robust and simple to update platform. It includes a secure Uptane-compliant over-the-air update solution using OSTree.
Founderies.io provides continuous updates to Linux microPlatform, as they believe the latest software is the most secure software.
Toradex also elaborates on its plans to simplify developers’ lives with its Torizon platform leveraging Linux microPlatforms, such as simplifying application development, enabling a modern DevOps workflow and easing migration from Windows-based systems.

Linaro’s Linux Kernel Functional Test framework (LKFT)
Posted by – October 6, 2018
Category: Exclusive videos, Linaro Connect
Linaro LKFT build uses OpenEmbedded to build a userspace image, along with the kernel, for each board and branch combination under test.
LKFT is Linaro’s Linux Kernel Functional Test framework.
The mission of LKFT is to perform functional regression testing on select Linux kernel branches in real time (as they’re updated) and report any regressions as quickly as possible. This is performed by executing a variety of functional-tests on a selection of user-space operating systems.
The goals of LKFT are to shorten derivative Linux kernel release intervals, increase the confidence of upstream Linux kernel engineers in the quality of their releases, and increase the confidence of downstream adopters of those Linux kernel trees. Ultimately the goal is that LKFT will encourage downstream hardware vendors to more frequently update the Linux kernel that runs on their devices in order that consumers might benefit from bug and security updates.
As part of Linaro’s mission to improve the Arm architecture eco-system, the LKFT team reports discovered regressions to Linaro kernel developers, Linaro members, and upstream Linux kernel engineers.
It is important to the Arm eco-system that Linaro also fix as many failures as are found. The LKFT team invests time into identifying, reporting, and fixing upstream kernel regressions, identifying kernel regressions in select member-hardware SoC (system-on-a-chip) trees, fixing test-suites by contributing to upstream testing projects, fixing kernel configurations, improving full OS stack integration (firmware, kernel, userspace), and improving Arm device automation integration.
UEFI at Linaro Connect Vancouver 2018
Posted by – October 6, 2018
Category: Exclusive videos, Linaro Connect
Unified Extensible Firmware Interface (UEFI) is a specification for a software program that connects a computer’s firmware to its operating system (OS). UEFI is expected to eventually replace BIOS. Like BIOS, UEFI is installed at the time of manufacturing and is the first program that runs when a computer is turned on.

This demo is based and tested on the DragonBoard 820c, but should be able to work on varying platforms. In summary, it counts objects by color passing in the same direction through the camera field of view. It can count multiple objects simultaneously. The OpenCV functionality leveraged by this demo includes the following:
– Object segmentation using color
– Valid object identification by size
– Frame stitching to track and count multiple simultaneous moving objects by color
– Provides hooks to monitor performance when algorithm changes to – – OpenCV library calls are made for identification tuning
– Provides hooks to export results to the cloud

Standardizing software support for 96Boards with Mani
Posted by – September 26, 2018
Mani is an Applications Engineer at 96Boards team of Linaro. He works on improving the user experience with 96Boards by upstreaming it’s stadardized software support. He goes over the journey of how he started with 96Boards, what his initial responsibilities were and how it has been evolved over time. He also explains his recent work towards standardizing the software support for 96Boards and stresses the importance of having a unified software layout across all 96Boards of same category. In this video, he mentions his latest work towards standardizing the LED labels/triggers in Linux kernel and how that impacts the user experience on userspace library such as MRAA (https://github.com/intel-iot-devkit/mraa).
MRAA library with Mani of 96Boards
Posted by – September 26, 2018
MRAA (https://github.com/intel-iot-devkit/mraa) is a low level skeleton library for Linux based systems which provides userspace access to the peripherals on 96Boards Consumer Edition boards using multiple interfaces such as C, C++, Python, Java and Javascript. Mani, being the Co-Maintainer of this library, talks about the history of how 96Boards started using this library instead of their legacy 96BoardsGPIO library. Also, he explains how the MRAA library serves well for them to handle multiple 96Boards with different SoCs which no other platform is doing.

Arm NN and the Linaro Machine Learning Initiative
Posted by – September 24, 2018
Jem Davies is the General Manager of the Machine Learning Group at Arm, he talks about the new Machine Learning Collaboration with Arm NN and Linaro, where Arm is donating the Arm NN inference engine and software developer kit (SDK) to Linaro’s Machine Intelligence Initiative. As part of this initiative – which aims to be a focal point for collaborative engineering in the ML space – Arm is also opening Arm NN to external contributions.
Linaro’s Machine Learning Initiative will initially focus on inference for Arm Cortex-A SoCs and Arm Cortex-M MCUs running Linux and Android, both for edge compute and smart devices. The team will collaborate on defining an API and modular framework for an Arm runtime inference engine architecture based on plug-ins supporting dynamic modules and optimized shared Arm compute libraries. The work will rapidly develop to support a full range of processors, including CPUs, NPUs, GPUs, and DSPs and it is expected that Arm NN will be a crucial part of this.
