Linaro brings standardization to edge device firmware through the Trusted Substrate Project

Linaro Ltd, the open source collaborative engineering organization developing software for the Arm® ecosystem, today announced the availability of a white paper on the importance of standardized firmware and its efforts to do so.

Cambridge, United Kingdom, July 13, 2021 /WebWire/ – Linaro has a track record of bringing Arm vendors together on the Linux kernel and is currently extending this to firmware with the Trusted Substrate Project. To download the White Paper “Standardization in Edge Device Firmware” click here.

Technologies such as IoT, AR, VR, Robotics and Machine Learning are increasingly part of our everyday lives and it is clear that we are heading in the direction of always being connected and online. While this connected world delivers countless benefits, it also presents challenges for those building the IoT solutions. How do you keep data secure and protect devices from cyber attacks? How do you keep devices up to date with the latest software? And how do you do all of this in a cost-effective and sustainable way?

Linaro has gathered perspectives from companies such as Bosch Rexroth, Microsoft, Red Hat and ST Microelectronics to understand the obstacles they face when building IoT solutions. From the mismatch between the lifetime of a machine vs the lifetime of the embedded technology, to the lack of integration between firmware components, the wide range of diverse use cases and the challenge of securing devices at scale – one thing is clear. Everyone is spending an excessive amount of time on solving problems which are common to all. The only way to tackle these challenges is through open standards and open interfaces.

About Trusted Substrate

Trusted Substrate is a collaborative project for the integrated, tested and packaged foundation of open source secure boot and trusted execution environments. The project is a BIOS which brings standards based secure booting and over-the-air (OTA) updates to the most trust demanding embedded computing projects such as automotive and robotics. By choosing Trusted Substrate enabled boards, product makers can rest assured that the behavior of their product will be consistent across SoCs and boards.

Intelligent fall detection using TI mmWave radar sensors

Sponsored by Texas Instruments

Actively sense when a fall has occurred and take action such as sending out an alert in response. Our 60GHz antenna-on-package radar sensor (IWR6843AOP) is ideal for fall detection applications since it’s able to detect falls in large, indoor environments, can distinguish between a person sitting and falling, and utilizes a point cloud vs a person’s identifiable features, which allows the sensor to be used in areas where privacy is vital such as bathrooms and bedrooms.
