EBBR: Embedded Base Boot Requirements at Linaro Connect

Posted by Charbax – November 5, 2018

Standard pre-boot environment and boot sequence for embedded platforms, featuring:
- Upstream support in U-Boot
- UEFI ABI
- Firmware-provided system description (DT)
- Boots generic OS images
By standardizing the boot interfacei, platform specific details don't need to be encoded into the OS, and the ABI supports portable pre-boot applications for test and boot control, future work will be on the more standard UEFI featured (e.g. Secure Boot).

Android Treble on Texas Instruments Beagle-X15 at Linaro Connect

Posted by Charbax – November 5, 2018

Android Treble implemented on TI Beagle-X15 development board which is ARM Cortex-A15, making the upgrade process easier. So there is no need to communicate with the vendor to upgrade a device.

Linux microPlatform, secure IoT updates with Foundries.io and Toradex

Posted by Charbax – October 13, 2018

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.

Google IoT Demo for Zephyr RTOS With TF-M Secured on Musca

Posted by Charbax – October 6, 2018

In this demo, the Trusted Firmware M is providing the SPE and JWT sign, Zephyr is providing the NSPE and The Google IoT application is running on Zephyr using secure services from Trusted Firmware M.

- Platform Security Architecture (PSA) is an IoI security framework being developed by Arm.
- Trusted Firmware M (TF-M) is an open source project to provide PSA compliant secure firmware for M profile devices.
- Zephyr is a Linux Foundation Collaboration Project to provide a small, scalable RTOS for connected, resource constrained device.
- Arm Musca-A1 subsystem based on Armv8-M which allows partitioning the SW execution in Secure and Non Secure domain.

Testing Arm with Arm with LAVA and 96Boards

Posted by Charbax – October 6, 2018

This is a mini LAVA lab running on a Dragonboard 410c to test any other 96Boards, this is a way to use Arm to test Arm boards in a simple affordable reproducible way.

OpenCV Color Segmentation and Tracking on DragonBoard 820c

Posted by Charbax – October 5, 2018

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 Charbax – 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 Charbax – 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.
