Cortex-M55 based Arm Virtual Hardware is now available in AWS Cloud

The Arm DevSummit 2021 is taking place on October 19-21, and the first announcements from Arm are related to IoT with “Arm Total Solutions for IoT delivering a full-stack solution to significantly accelerate IoT product development and improve product ROI”, “Project Centauri” aiming to achieve for an extensive Arm Cortex-M software ecosystem in the way that Project Cassini does for the Cortex-A ecosystem, starting with support for PSA Certified and Open-CMSIS-CDI cloud-to-device specification, and Arm Virtual Hardware based on Corstone-300 IoT platform with a Cortex-M55 MCU core and an Ethos-U55 microNPU accessible from Amazon Web Services. The first two are quite abstract right now, and more information may become available in the future, but the Arm Virtual Hardware is available now from AWS as a public beta, with 100 hours of free AWS EC2 CPU credits for the first 1,000 qualified users. The virtual hardware does not emulate only the […]

Timesys Embedded Board Farm enables remote access to hardware for software development & QA

When you design a new board with an international team working in multiple locations, there may only be a couple of boards available for testing, and that’s mean some members of the team may not have access to the hardware. The same problem can be true for test farms with a larger number of boards. So it would be good to have a solution to remotely access and control the hardware to speed up development. A few years ago we wrote about MuxPi board using NanoPi NEO SBC to enable remote testing of development boards, but now Timesys has come up with a more advanced solution with the Embedded Board Farm (EBF) capable of sharing multiple boards across teams spread around the world. The solution is comprised of three main components besides the target boards: The Master Server integrated with LAVA test automation framework – It handles docker images, firmware/file […]

MuxPi Board Relies on NanoPi NEO to Enable Remote Testing of Development Boards

Product development often occurs in different location over the world, there may be one team in Asia, and another in Europe and the US. At the beginning, the number of working samples for a board may be limited, so the project manager may have to decide who gets the boards since those may not be available to all teams. So it would be great if somehow there was a way to do remote testing of boards, so maybe the team in Asia could setup the testbed, used it during there time, and once they are back home, the US team can take over remotely to carry on their own development work on the hardware. That’s exactly what MuxPi board is all about. The solution provide remote access via the Ethernet port of a NanoPi NEO board, and connects to the DUT (Device under Test) via HDMI, Ethernet, USB and other […]

Astro Design HDMI Test Equipment Supports 8K @ 120 Hz

8K media players and 8K TVs are coming, but if you develop one of those products how do you test them since 8K players/TVs are not available just yet. Answer: Test equipment. Astro Design offers just that with their VG-879 digital video generator, as well as their VA-1844A HDMI protocol analyzer. VG-879 digital video generator key features: 4K/60p is transmitted by one channel of 12G-SDI. Max.4 slot-type interface units can be selected from 12G-SDI, HDMI2.0b 3G or 6G, DisplayPort 1.2a, V-by-One and Analog. By synchronizing 4 or 2 units of VG-879, 8K/120p or 8K/60p signals are supported. (8K/120p by V-by-One HS, 8K/60p by V-by-One HS and HDMI.) HDMI 2.0b test functions supported EIA CEA-861-F Timing Format including 4K/50, 60p, YCBCR 4:4:4/4:2:2/4:2:0 timing. SCDC parameter change and status display. ITU-R BT.2020 color bar and video output setting 4K6G with Scrambling Enable setting CEA-861.3 HDR (High Dynamic Range) InfoFrame setting HDR Test Patterns supported […]

Nutaq PicoLTE IoT Kit Allows NB-IoT and LTE Cat M1 Devices Testing Anywhere

If you’ve been following cellular IoT news you must have read plenty of announced about NB-IoT and LTE Cat M1 (eMTC) hardware platforms bring LTE connectivity at lower power and somewhat lower cost than existing 3GPP networks. That’s all good, and you may have decided to go ahead with a commercial project, except none of the Telco are providing LTE IoT connectivity in your area just yet, or if it does, you may also want to test your device in bands not allowed/supported in your country (at a permitted power level). If that’s the case, Nutaq PicoLTE IoT Kit should help as an LTE NarrowBand & Cat M test measurement platform for IoT that can test NB-IoT and Cat-M1 devices in all frequency bands. Nutaq PICOLTE IoT kit key features: Supports M1 & NB-IoT devices Proven compatibility with M1 & NB-IoT devices from over 5 manufacturers Test multiple devices simultaneously […]

Lab in a Box Concept Embeds x86 Server and 6 ARM Boards into a PC Case for Automated Software Testing

The Linux kernel now has about 20 millions line of code, Arm has hundreds of licensees making thousands of processors and micro-controllers, which end up in maybe hundreds of thousands of different designs, many of which are not using Linux, but for those that do, Linux must be tested to make sure it works. The same stands true for any large software used on multiple hardware platforms. Manual testing is one way to do it, but it’s time consuming and expensive, so there are software and hardware continuous integration solutions to automate testing such as Linaro LAVA (Linaro Automated Validation Architecture), KernelCI automated Linux kernel testing, and Automotive Grade Linux CIAT that automatically test incoming patch series. Both CIAT and KernelCI focus on Linux, and rely on LAVA, with KernelCI leveraging hardware contributed by the community, and proven to be effective as since it’s been implemented, failed build configs dropped […]

USBCEE Tiny-PAT Board Helps Testing USB-C Power Adapters (Crowdfunding)

USB power delivery allows for up to 100W charging using 20V @ 5A through a USB type C port, and the specifications also mandate supports for various voltages between 5V and 20V. However, some USB-C power adapter that not be fully compliant with the specifications, potentially risking to damage your device. USBCEE Tiny-PAT board has been created in order to test such power adapters to make sure they are compliant with USB PD 2.0/3.0 specifications. Tiny-PAT board features and specifications: Supported USB Spec Version – PD 2.0 / PD 3.0 Max Voltage: 24 V Max Current: 5 A Max Power: 100 W USB type C receptacle Misc – Fail and Pass LEDS, S4 mode button, through holes for VBUS & GND Power Consumption: ~10 mA (may vary based on voltage) Dimensions – 35 x 20 mm By default, the board will test all power rules advertised by the power adapter, […]

Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]
