Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]

Renesas’ first 32-bit RISC-V CPU core delivers up to 3.27 CoreMark/MHz

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on the open-standard instruction set architecture (ISA). This CPU core is compatible with Renesas’ e2 studio IDE and supports other third-party IDEs for RISC-V MCUs. According to Renesas, the CPU achieved a remarkable 3.27 CoreMark/MHz performance outperforming similar RISC-V architectures in this category. RISC-V, an open ISA, is rapidly gaining popularity in the semiconductor industry. Many MCU providers have formed joint investment alliances to expedite their RISC-V product development. Previously, Renesas released two CPUs developed by Andes Technology Corp: the R9A02G020, an ASSP EASY MCU for Motor Control, and the R9A06G150, an ASSP EASY MCU for Voice HMI, both based on RISC-V. Additionally, they have introduced the RZ/Five, a Linux-capable 64-bit RISC-V microprocessor family, and RH850/U2B, an automotive System on Chip (SoC).  However, with the release of their new CPU, Renesas independently enters the RISC-V market, highlighting their […]

Giveaway Week 2023 – WCH CH583M-R0 development board and some RISC-V microcontrollers

Early this year, WCH sent me a few of their RISC-V MCU boards and chips to thank me for writing about their products. I gave one for review with some chips but it went to review heaven, or in other words, no review was ever written. I also sold a couple locally, and since I don’t think I’ll ever have time for a review, we are now giving away the remaining boards and chips here and on CNX Software Thailand. Today’s giveaway is the WCH CH583M-R0-1v1 board, also known as CH583EVT or CH583M-EVT-R0, based on the CH583 RISC-V Bluetooth 5.3 LE microcontroller that exposes all I/Os from the chip, a few buttons, and USB ports, and also features an SWD/UART header for debugging. You’ll find the documentation, code samples, an Android app and other resources to get started on GitHub. I’ll also throw all the remaining chips I have left […]

$150 BeagleV-Fire SBC features Microchip PolarFire RISC-V SoC FPGA, supports BeagleBone capes

BeagleV-Fire is a new single board computer powered by Microchip PolarFire MPFS025T penta-core RISC-V SoC FPGA that follows the BeagleBone Black form factor for compatibility with BeagleBone capes expansion boards. Microchip PolarFire RISC-V SoC FPGA was one of the first Linux-compatible RISC-V SoCs and was found in pricey boards such as the Icicle and TySOM-M-MPFS250 development boards. I also got an Icicle board for review, and while getting started with the Yocto Linux BSP was OK, I really struggled with the FPGA part including just installing Libero SoC in Ubuntu and going through the license, and even I gave up trying to run a bitstream sample on the board due to a lack of time. The BeagleV-Fire makes it much cheaper to try out the PolarFire and hopefully makes it easier to get started with both Linux and the FPGA fabric through easier-to-understand documentation and code samples. BeagleFire-V specifications: SoC […]

Linux 6.6 LTS release – Highlights, Arm, RISC-V and MIPS architectures

The Linux 6.6 release has just been announced by Linus Torvalds on the Linux Kernel Mailing List (LKML): So this last week has been pretty calm, and I have absolutely no excuses to delay the v6.6 release any more, so here it is. There’s a random smattering of fixes all over, and apart from some bigger fixes to the r8152 driver, it’s all fairly small. Below is the shortlog for last week for anybody who really wants to get a flavor of the details. It’s short enough to scroll through. This obviously means that the merge window for 6.7 opens tomorrow, and I appreciate how many early pull requests I have lined up, with 40+ ready to go. That will make it a bit easier for me to deal with it, since I’ll be on the road for the first week of the merge window. Linus About two months ago, […]

CanMV-K230 AI development board features Kendryte K230 dual-core 64-bit RISC-V processor

CanMV-K230 is a credit card-sized development board for AI and computer vision applications based on the Kendryte K230 dual-core C908 64-bit RISC-V processor with built-in KPU (Knowledge Process Unit) and various interfaces such as MIPI CSI inputs and Ethernet. The first Kendryte RISC-V AI processor was launched in 2018 with the K210 which I tested with the Grove AI HAT and Maixduino board and found fun to experiment with, but noted that performance was limited. Since then the company introduced the K510 mid-range AI processor with a more powerful 3 TOPS AI accelerator, and the K230 entry-level successor to the K210 – which was planned for 2022 in a 2021 roadmap – has now just been launched and integrated into the CanMV-K230 development board. CanMV-K230 specifications: SoC – Kendryte K230 CPU 64-bit RISC-V processor @ 1.6GHz with RISC-V Vector Extension 1.0, FPU 64-bit RISC-V processor @ 800MHz with support for […]
