Microsoft is Working with Mediatek on Project Sopris Secure WiFi MCU

There are serious security issues with the Internet of Things at all levels: hardware, software, network, and end-users. Microsoft Research NExT Operating Systems Technologies Group has been tasked with “exploring the goal of securing the vast number of low cost Internet connected devices coming online” with Project Sopris. They have shared their first technical report that identifies “seven properties of highly secure devices”, and describes their experiments towards designing microcontroller based prototype devices adapted from Mediatek MT7687 MIPS microcontroller, and exhibiting those seven properties. The seven properties identifies by Microsoft team include: Hardware-based Root of Trust – Unforgeable cryptographic keys generated and protected by hardware. Physical countermeasures resist side-channel attacks. Small Trusted Computing Base – Private keys stored in a hardware-protected vault, inaccessible to software. Division of software into self-protecting layers. Defense in Depth – Multiple mitigations applied against each threat. Countermeasures mitigate the consequences of a successful attack on […]

New 96Boards IoT Edition Boards Showcased at Linaro Connect 2017: BlueSky IE and WRTNode IE

Linaro Connect Budapest 2017 is taking place this week in Hungary, and during George Grey – Linaro CEO – keynote, he provided a status updates for the Linaro group, addressed some of Linaro’s criticisms from members and the community, and unveiled two upcoming boards compliant with 96Boards IoT edition both running Zephyr OS, and adding to BLE Carbon board announced last year. The first board is BlueSky IE board with the following key specifications: SoC – RDA Micro RDA5981A ARM Cortex-M4 Wireless MCU with 64KB ROM, and 32KB cache System Memory – 485KB SRAM. It’s unclear if that’s only the on-chip SRAM, and there’s also some external PSRAM added. Storage – 8Mb NOR flash 802.11 b / g / n HT20 / 40 mode Connectivity – 802.11 b/g/n WiFi with support for HT20 / 40 modes Crypto security hardware The second board is WRTnode IE: SoC – Mediatek MT7697 ARM […]

Mediatek MT2533D is a Bluetooth 4.2 SiP for Smart Headphones & Hands-Free Systems

There used to be a time when most products were based on a general purpose MCU or processor that you would interface to over chips like audio codecs, memory chips, flash storage, etc…, but in order to cut costs, application specific SoCs have become quite common over the year, so we’ve had mobile application processors for several years already, but more recently we got “wearables” SoCs and “Smart Home” SoCs, and Mediatek has launched MT2533D “headphone” SiP (System-in-Package) combining a Cortex-M4 MCU, 4MB PSRAM, an audio codec, and a dual mode Bluetooth subsystem. Mediatek MT2533D specifications: MCU – ARM Cortex-M4 @ up to 208MHz with 32KB L1 cache, FPU, MPU, AES 128/192/256 crypto engine and TRNG Memory – 160kB SRAMs, 4MB pseudo SRAM Storage – 4MB flash Wireless Connectivity – Bluetooth 4.2 dual mode (classic and low energy) Audio AAC/SBC for Bluetooth audio CVSD/mSBC for Bluetooth speech PCM playback: 8-48kHz […]

Mediatek Introduces Helio X23 and X27 Processors with Faster Clocks, Better Camera Support, Lower Power Consumption

Mediatek has just announced upgrades to their Helio X20 and X25 deca-core processors with respectively Helio X23 and X27 boasting higher CPU and GPU frequencies, higher camera quality, as well as lower power consumption thanks to MiraVision EnergySmart Screen power-saving technology. The two new processor still feature MediaTek tri-cluster deca-core architecture with two ARM Cortex A72 cores, four ARM Cortex A53 core, and 4 more low power Cortex A53 cores, but Helio X23 Cortex A72 cores’ max CPU frequency increased from 2.1 GHz to 2.3 GHz, and Helio X27 got a small boost to 2.6 GHz for the Cortex A72 cores (vs 2.5 GHz) and 1.6 GHz for the low power Cortex A53 cluster, as well as a higher frequency ARM Mali-T880 MP4 GPU at 875 MHz instead of 850 MHz for Helio X25. MediaTek Helio X23 and X27 also support dual camera photography with the upgraded MediaTek Imagiq image […]

How Fix Apps Crashing at Launch in Android 6.0 (in Mediatek Phones) ?

I’ve recently received a new Android 6.0 Marshmallow smartphone powered by Mediatek Helio X20 processor, namely Vernee Apollo Lite, and one of the issues I encountered is that some applications such as Firefox and MAPS.ME would crash when I tried to launch them. The problem was reproducible 100% of the time, and occurred from the very first time I tried to start the app. I’d get a message like “Unfortunately MAPS.ME has stopped” with two buttons: REPORT or OK. So I asked on Vernee forums to report the issue, and see if other people had the same problem. One replied had the same problem, but a simple reboot would fix the issue, while the other proposed to clear the cache. I had not considered that option since the crash occurred from the very first time, but I tried anyway. Go to the App list, drag and drop the problematic app […]

Mediatek Helio X30 Deca-core SoC Features ARM Cortex-A73, Cortex A53, and Cortex A35 Processor Cores

Mediatek introduced Helio X20 last year with a tri-cluster architecture comprised of 2 powerful ARM Cortex A72 cores, 4 Cortex A53 cores, and 4 extra Cortex A53 cores operating at a lower frequency, and optimized for power consumption. But now that ARM has introduced ultra-low power Cortex A35 cores, and more powerful Cortex A73 cores, the Taiwanese company has been able to improve its tri-cluster implementation for the upcoming Helio X30 deca-core processor with 2 Cortex A73 cores @ up to 2.8 GHz, 4 Cortex A53 cores @ up to 2.2 GHz, and 4 Cortex A35 cores @ up to 2.0 GHz. According to various sources on Weibo, the mobile processor also includes an Imagination PowerVR 7XT GPU, supports up to 8GB LPDDR4 RAM @ 1600 MHz (PoP – Package in Package), UFS 2.1 flash storage, up to 40MP camera sensors, and its cellular modem will support LTE Cat.10 to […]
