OpenISA VEGAboard Combines RISC-V and ARM Cortex-M Cores

VEGAboard

OpenISA has launched an Arduino compatible RISC-V development called VEGAboard that features RV32M1 wireless microcontroller with a RISC-V RI5CY core, a RISC-V ZERO-RISCY core as well as Arm Cortex-M4F and Cortex-M0 cores, and a radio operating in the 2.36 GHz to 2.48 GHz range. An external NXP Kinetis K26 Arm Cortex-M4 MCU is added to the board for OpenSDA (Open-Standard Serial and Debug Adapter) debugging over a single USB cable.

NXP Unveils A71CH Secure Element Chip for Secure Peer-to-Peer or Cloud Connections

The industry clearly has an issue at hand with the security of the Internet of Things, and the problem is complex as some devices are easily accessible due to bad configuration (e.g. default username/password), while others may have security flaws at various levels of the software stack from the low level bootloaders to the operating systems, and applications. Nowadays, devices also need to be upgradeable, and communicate with the cloud, and that introduces other attack vectors in case malignant firmware is installed instead, or a man-in-the-middle attack occurs. While some people may claim security can be achieved by software only, we are seeing security evolving towards combined software and hardware solutions, for example with Arm Trustzone built into SoCs, but some companies are also introducing Secure Element chip, which Samsung has already done and integrated into their Artik  modules to secure data from the hardware to the cloud. NXP has now also launched their own A71CH Secure Element (SE), described …

A Closer Look at Ingenu RPMA Alternative to LoRa or Sigfox LPWAN Standards & RPMA Development Kit

I’ve recently started to write a bit more about long range LPWAN standards for IoT applications, especially LoRa and Sigfox, as commercial networks are being launched, and relatively low cost hardware platforms are being introduced to the market. There are also other highly expected standards such as Weightless and LTE Cat M that will bring more competition to the market. Ingenu RPMA (Random Phase Multiple Access) is another available standard that’s been in deployment for a while, and based on an earlier comparison of  long range LPWAN standards, it comes with long range, supports up to 384,000 nodes per “sector”, operates in the unlicensed 2.4 GHz ISM band, and offers high combined uplink and downlink bandwidth than competitors. Ingenu recently contacted me and provided some more details and information about their technology and development kit. One of the documents includes an “independent analysis completed by ABI Research, Inc.” comparing features of Sigfox, LoRa, EC-GSM-IoT, MB-IoT, LTE Cat-M1,  and RPMA. All …
