Imagination Solution to FCC Rules for WiFi Routers: Run OpenWrt / DD-WRT and the WiFi Driver in Separate Virtual Machines

About a year ago, discussions started about new rules from the FCC that could prevent routers from installing open source third party operating systems such as OpenWrt or DDWRT. Despite the FCC assurance that the rules were meant to prevent some users from illegally tweaking the RF settings, and that it would not have to impact installing of open source alternatives, the reality is that companies such as TP-Link ended up locking their routers up due to the new rules, while Linksys would only ensure OpenWrt/ DD-WRT compatibility on some of their routers, but not all. Companies are probably doing that due to the extra work that would be required to separate the RF settings which need to be locked, and the rest of the firmware. But Imagination Technology’s prpl security group has a solution for their MIPS Warrior P-Class processors using hardware virtualization. In order to show the concept […]

MeegoPad A02 Remix OS TV Stick Has Now Launched on Indiegogo for $39 and Up

MeegoPad A02 octa-core Remix OS first launched in China for as low as 199 CNY ($30), and the company has raised around 107,000 RMB (~$16,300 US) so far. In the meantime, they’ve also launched the product on Indiegogo for a ~25% markup for cheapest pledge as the 1GB RAM/16GB Flash is offered for $39 + shipping, instead of $30 + shipping in China. The specifications have not changed much (some features have been clarified), and there are still two models with different memory and storage capacities: SoC – Allwinner A83T octa-core ARM Cortex-A7 @ 1.6 GHz with PowerVR SGX544MP1 GPU System Memory / Storage 1GB DDR3L + 16 GB eMMC flash, and micro SD slot up to 128GB OR 2GB DDR3L + 32 GB eMMC flash, and micro SD slot up to 128GB Video Output – HDMI 1.4 up to 1080p60 Audio Output – HDMI, 3,5 mm headphone jack Connetivity […]

Bluetooth 5 Promises Four times the Range, Twice the Speed of Bluetooth 4.0 LE Transmissions

The Bluetooth SIG is about to officially unveil Bluetooth 5 on June 16 during a media event in London. One change on the marketing side is that they dropped the point number, so it won’t be called Bluetooth 5.0 like in Bluetooth 4.0, but just Bluetooth 5. The decision has been made allegedly to “simplifying marketing, and communicating user benefits more effectively”. On the technical side, Bluetooth 5 will double the speed and quadruple the range of low energy Bluetooth transmissions compared to Bluetooth 4.x, which could be important for IoT applications where nodes are connected throughout the house. Bluetooth 5 will also allow connectionless services to add location-relevant information and navigation. The specifications have not been publicly released yet, and made they will be on June 16. Eventually, you’ll be able to download them on Bluetooth “adopted specifications” page. Via XDA developers

Raspberry Pi 3 To Get ARM TrustZone Support with Linaro OP-TEE Port

If you ever wanted to experiment with ARM Trustzone, and IoT security, you’ll soon be able to do so with the Raspberry Pi 3 board thanks to a port of Linaro OP-TEE (Open Portable Trusted Environment Execution) by Sequitur Labs. Broadcom BCM2737 SoC found in Raspberry Pi 3 board already had TrustZone hardware for isolation and protection for sensitive material such as cryptographic keys, algorithms and data, but the upcoming software release will mean the feature can now be used, and it’s free for trial/evaluation, and education. Trustzone is also used for DRM (digital rights management), but in the case of Raspberry Pi 3 it will most likely used to teach how to secure the Internet of Things (IoT). The release is scheduled for July 11, with source code and documentation to be available in OP-TEE github account. All you’ll need to get started is a Raspberry Pi 3 board, […]

Orange Pi PC Plus Quad Core Development Board with 1GB RAM, 8GB eMMC flash Sells for $20

Most low cost development boards do not include internal storage in order to decrease costs, and instead require their users to flash their preferred operating system on (micro) SD card. This makes it easy to get started, but many micro SD cards often suffer from poor random I/O performance, even for Class 10 or greater card, leading to a poor user experience compared to what you’d get with an eMMC flash. Shenzhen Xunlong has released yet another Allwinner H3 board, namely Orange Pi PC Plus, similar to Orange Pi PC but adding WiFi, and 8GB eMMC flash. Orange Pi PC Plus specifications with main change with Orange Pi PC highlighted in bold: SoC – Allwinner H3 quad core Cortex A7 @ 1.3 GHz with ARM Mali-400MP2 GPU up to 600 MHz System Memory – 1GB DDR3 Storage – 8GB eMMC flash + micro SD card slot Video Output – HDMI […]

Frosted OS is an Open Source POSIX Operating System for Cortex-M Micro-controllers

Frosted, which stands for “Free Operating Systems for Tiny Embedded Devices”, is an OS with a POSIX-compliant system call API, borrowing the Linux kernel kconfig for configuration, and currently supporting ARM Cortex M0,M3,M4, and M7 MCU including Texas Instruments Stellaris LM3S, STMicro STM32F4/F7, and NXP LPC17XX micro-controllers. The developers are focusing on IoT applications, as well as porting retro-games such as Doom. The kernel relies on libopencm3 for hardware abstraction, and the operating system can be built with GCC ARM for Frosted using the source code released under a GNU GPLv2 license. The Wiki explains how to build and run the OS on either Qemu (in a Linux computer) used LM3S target, or an STM32F4 Cortex -M4 or STM32F7 Cortex-M7 board. The team also uploaded showing a video of Doom (fdoom) running on STM32F7 board, and possibly adapted from stm32doom port. If you are interested in joining the project you can […]
