2x 8-pin GPU power connectors.

Each CPU can support upto 8 DDR4 DIMMs. The front 2.5" drive bay supports upto 2 drives. An optional 3.5" storage bay holds 4 drives. Initially, 2.2GHz 32-core 4-threads per core. Other SKUs will be available depending on demand. Various nVidia video cards have been tested with the open source Nouveau driver. Initial shipments include the nVidia GeForce 710 with dual monitor support. The AMDGPU driver has been tested with various AMD GPUs. Additional AMD and nVidia GPUs are being tested. Initial shipments include a 1 GbE PCIe adapter. If standard PCIe slots are in short supply a QLogic dual port 1/10 GBaseT RJ45 OCP adapter and driver are available. Units ship with Ubuntu 17.10. CentOS 7.4 and OpenSUSE are also available. Pricing is competitive with high end single and dual socket workstations from leading name brand workstation vendors with comparable Gold/Platinum processors.

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.

Internet of Tiny Linux, Google IoT on ARM Cortex-A5 memory constrained device

Posted by Charbax – November 5, 2018

Nicolas Pitre of Linaro and his team have worked to reduce the size of the Linux kernel and user space binaries to make them suitable for very small IoT applications to enable the Internet of Tiny Linux. Here at Linaro Connect Vancouver 2018, Linaro shows mainline Linux kernel for IoT devices, running with as little as 4MB of RAM here for example Google IoT.

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.

Linaro’s Linux Kernel Functional Test framework (LKFT)

Posted by Charbax – October 6, 2018

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 Charbax – October 6, 2018

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.

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.
