BL602 IoT SDK and $5 DT-BL10 WiFi & BLE RISC-V development board

Yesterday, we wrote about Bouffalo BL602 32-bit RISC-V WiFI and Bluetooth LE wireless SoC that should eventually compete with ESP8266 in terms of price but with more features, higher performance. and more resources like memory and storage. At the time, I noted I could not find any tools for the processor, but I was informed a BL602 SDK (Doiting_BL) and documentation had already been released on Github. The basic readme and a user manual are already available in English, but the main documentation is still in Chinese with various examples to configure GPIO, YART, WiFi, and Bluetooth. You’ll find the documentation in Github, as I could not find a website yet:

git clone https://github.com/SmartArduino/Doiting_BL

1	git clone https://github.com/SmartArduino/Doiting_BL

Go to Doiting_BL/docs/html folder and then open index.html in your browser to access the documentation. The SDK works both in Windows and Linux and relies on either Eclipse & OpenOCD or Freedom Studio & OpenOCD. A graphical software […]

CloudBEAR BM-310 RISC-V MCU core for IoT applications

In the pool of 32-bit RISC-V microcontroller cores (E20 by SiFive, VEGA ET1031 by C-DAC), CloudBEAR showcased its 32-bit small and efficient MCU core – BM-310 at RISC-V GLOBAL FORUM 2020. CloudBEAR works on providing services like processor IP customization, support for RISC-V ISA extensions, product integration within a system-on-chip, and configurable instruction and data cache. Let’s first look into the CloudBEAR processor IP portfolio. It has three different product lines- BM series, BR series, and BI series. First, the BM series targets small and efficient MCUs cores. Second, the BR series targets fast and compact embedded cores. The third and most important BI series is about Linux capable application cores. In this article, we will look into the details of BM-310, which is the RISC-V MCU core for embedded and IoT solutions. BM-310 Architecture As RISC-V is a modular instruction set, extensions are optional for the developer. BM-310 architecture […]

Linux 5.9 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes […]

MAX78000 RISC-V & Cortex-M4F MCU enables IoT artificial Intelligence in battery-powered devices

Now even endpoints like sensors are capable of running basic artificial intelligence workloads thanks to microcontroller-class chips with built-in AI accelerators or instructions such as Kneron KL720 Arm Cortex-M4 AI SoC, GAP8 RISC-V IoT processor, or Cortex-M55 MCU core coupled with Ethos U55 MicroNPU. Maxim Integrated has now launched its own AI capable microcontroller with MAX78000 combining a Cortex-M4F core, a 32-bit RISC-V core, and a CNN accelerator enabling AI inferences at less than 1/100th the energy or 100 times the speed of software solutions making especially suited for battery-powered AI applications. MAX78000 specifications: Ultra-Low-Power microcontrollers Arm Cortex-M4F core with FPU Up to 100MHz with 512KB Flash and 128KB SRAM 32-Bit RISC-V ultra-low-power co-processor up to 60MHz Neural Network Accelerator optimized for Deep Convolutional Neural Networks (CNN) 442k 8bit Weight Capacity with 1,2,4,8-bit Weights Input Image Size up to 1024 x 1024 pixels Network Depth up to 64 Layers Layer […]

SiFive to Debut RISC-V PC for Developers based on Freedom U740 next-gen SoC

In recent years, people have discussed the need to have Arm-based PCs or workstations for developers to work directly on the target hardware, and there are now several options including SynQuacer E-Series 24-Core Arm PC, Ampere eMAG 64bit Arm Workstation, and HoneyComb LX2K 16-core Arm Workstation. Now it appears we’ll soon get something similar for RISC-V architecture with SiFive to debut the first RISC-V PC for developers at the Linley Fall Processor Conference 2020 taking place on October 20-22 and October 27-29. The PC will be powered by Freedom U740 next-generation RISC-V processor that will also be introduced at the event. We have very few details about this point in time, but the company points the SiFive Freedom U740 (FU740) SoC will enable professional developers to create RISC-V applications from bare-metal to Linux-based. The processor is said to combines a heterogeneous mix+match core complex with modern PC expansion capabilities, which […]

PicoRio Linux RISC-V SBC is an Open Source Alternative to Raspberry Pi Board

There’s a lot of interest/hype around RISC-V, and low-cost boards such as Longan Nano or Maixduino are already available, but those are based on microcontroller-class chips, even though it’s possible to run Linux on Kendryte K210 RISC-V board, it comes without MMU, so it’s not for everyone. Linux capable RISC-V boards do exist but cost several hundred dollars or more with the likes of HiFive Unleashed and PolarFire SoC Icicle development kit. If only there was a RISC-V board similar to the Raspberry Pi board and with a similar price point… The good news is that the RISC-V International Open Source (RIOS) Laboratory is collaborating with Imagination technologies to bring PicoRio RISC-V SBC to market at a price point similar to Raspberry Pi. The PicoRio board was presented at the RISC-V Global Forum on September 3rd. I could not find the full presentation slides yet, but there are some screenshots […]
