The Linaro Digital Home Group (LHG) has achieved a milestone in the delivery of an open source reference solution for the consumption of premium content on ARM powered devices.
The media solution ulitizes several open source components coupled with a commercial DRM that executes in a Trusted Execution Environment (TEE). The TEE used is the Open Portable TEE (OPTEE) from Linaro, running on ARM TrustZone.
The solution integrates the following key components:
– W3C EME Working Draft (31 March 2015)
– Microsoft PlayReady DRM Porting Kit v3.0
– OP-TEE
– OpenCDM/OpenCDMi
– Chromium v43
The solution is powered by a STMicroelectronics STiH410 ARM Cortex-A9 processor.
Shenzhen Realtime show their balance scooter factory with assembly and testing lines. People ride those around the world, the speed can go up to 12km per hour, with 36W 4.4AH battery (charging time 2 hours), the cruising radius they say is up to 30km. The net weight of a smart balance wheel scooter is around 12kg, the Maximum load weight up to 125kg and maximum climbing angle is 15 degrees. They say that it is convenient or fun to ride those indoors at exhibitions, airports, in big office buildings, hotels and etc. Shenzhen Realtime’s price is around $180 for minimum orders of around 500pcs, contact them for info.

Qualcomm shows their AllJoyn open source project part of the AllSeen Alliance Internet of Everything development platform featuring the Qualcomm QCA4002 on the GT202 reference design development board with Freescale Freedomboard, Renesas RX11 and STMicroelectronics Microcontrollers, as well as launching the very low power Qualcomm QCA401x Wi-Fi chip that includes a RTOS based Microcontroller to power end-point devices like light bulbs and home surveillance cameras to answer manufacturer demand for increased computing, memory, and advanced features while lowering size, cost, and power consumption.
Using ST Microelectronics ARM Cortex-M4, MediaTek MT2502 ARM7EJ-S or Ingenic MIPS, using Sharp Memory LCD, E Ink or regular LCD, pricing from below $50 to $100 for an MT6572 dual-core ARM Cortex-A7 based Apple watch clone running Android. Mifree says that they are currently shipping more than 100 thousand smartwatches per month out of their smartwatch factory. Mifree also shows how they can add a PCB to a classical style watch to make it smart.
STMicroelectronics launches STM32 F7 series of very high performance Microcontroller Units based on the ARM Cortex-M7 core. The STM32 F7 devices are the world’s first ARM Cortex-M7 based 32-bit microcontrollers, improving on the benchmark performance. Taking advantage of ST’s ART Accelerator as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory: 1000 CoreMark/428 DMIPS at 200 MHz fCPU.
Demonstrated running on the STM32 F7, IS2T MicroEJ SDK enables embedded Java development for any MCU and MPU, from the smallest ARM Cortex-M0+ to the newest Cortex-M7 and beyond. The embedded Java platform includes IS2T Java Virtual Machine (footprint: 28KB of RAM, 1.5KB of RAM) and IS2T libraries for IoT, GUI and communication applications. Boot time to first line of Java main is 2ms on a Cortex-M4@120MHz.
IoT solutions includes TPC/IP, Wifi, MQTT, Websockets, HTTP, JSON, XML, COAP… protocols. GUI solutions includes a full set of widgets, drawing, motions, anti-aliased… libraries – typical animations at 60FPS with less than 10% CPU load. Full Java applications run on MCU starting from 256KB of flash.
The MicroEJ demo running on STM32F7 device shows the Waddapps store connection, an online store of embedded applications that can be downloaded to the STM32F7 through any link (e.g. ethernet, Wifi, Bluetooth). Apps are downloaded, installed, started, stopped, uninstalled without reset – same as smartphone users would typically do with an Apps Store.
The Linaro team ported the Chromium Embedded Framework to Linux running on ARM, the framework utilizes an EGL backend integrated using Chromium’s Ozone abstraction layer.
ST’s latest ARM Powered System-on-Chips supporting Android, Google TV (now Android TV), rdk, ST presents their STiH312 client-box and STiH412 server-box product families, codenamed ‘Cannes’ and ‘Monaco,’ respectively, they integrate Faroudja technology to decode and display video up to Ultra HD 4K (2160p) and the next-generation H.265 / HEVC video compression. Even supporting video transcoding (for local and remote streaming from the Set-top-box to Tablets, Smartphones, etc) STMicroelectronics presents their Dual core ARM Cortex-A9 (on 28nm process) with quad-core Mali-400 GPU does Quad-HD Ultra HD 4K HEVC video decoding, combined with Faroudja video processing technology (decoding on Cannes, decoding and transcoding on Monaco), advanced security supporting concurrent conditional access and DRM, wide connectivity, including USB 3.0, PCI-e, SATA and Gigabit Ethernet, Dedicated interfaces to a range of companion front-end solutions, including MoCA 2.0, DOCSIS 3.0, satellite and 802.11ac WiFi and more.
Linaro Security Working Group (SWG), Jens Wiklander, Joakim Bech, Pascal Brand and Cedric Chaumont are talking about what is happening within Linaro’s working group that handles security. The group is currently focusing on creating an open source Trusted Execution Environment (TEE) solution running on TrustZone® for ARMv7 and ARMv8 architecture. They also mention that they are going to work on secure boot (UEFI) and DRM schemes (EME) later on. According to SWG there has been and is a lot of interest shown from various companies, markets and countries. People have a hard time trusting a black box that is supposed to protect their most valuable assets. Therefore it is more than welcome to create an open source TEE solution right now, says SWG.
The Unbound Robotics UBR 1 is a robot that uses a combination of both ARM Cortex and x86 processors. The UBR 1 is designed as a platform for robotics development and uses ROS (robotics operating system) which is open source. The main processor currently in the robot is an x86 but it uses 12 ST Microelectronics ARM Cortex-M4 based microcontrollers to control each part of the robot.
ARM is showing Motor Control comparing two rotating water vessels, one controlled in a conventional manner, the other is controlled in a more advanced algorithm called Field Oriented Control on a STM32 Cortex-M3 processor. This more advanced algorithm allows more efficient operation of the motor, better control of the torque and allows for quieter operation. The idea is to use less power to control motors. This is just the start of their investigation into Field Oriented Control using the Cortex-M3 processor.
