XuanTie C906 based Allwinner RISC-V processor to power $12+ Linux SBC’s

Allwinner XuanTie C906 RISC-V Processor

Alibaba unveiled Xuantie-910 RISC-V core (aka XT910) in 2019 for powerful SoC with up to 16 cores, but an update in 2020 revealed the company planned to have a complete RISC-V core family for a wide range of application from low-power microcontrollers to server SoCs. At the time, I just assumed the company planned to keep their cores to themselves, but time proved me wrong as T-Head, the Alibaba subsidiary in charge of developing RISC-V cores, started to cooperate with Allwinner to develop open-source processors, which should lead to low-cost Linux capable RISC-V SBC very soon according to a tweet from Sipeed. Good News: We get first chip which based on XuanTie C906 (RV64GCV), it have abundant interface (HDMI/RGB/DVP/MIPI/GMAC/…), and will be able to run Debian system.Last and most important, the basic dev board price is start at 12.5$ (1% of HiFive Unleashed)。 pic.twitter.com/EJbXTJ5eMb — Sipeed (@SipeedIO) November 6, 2020 […]

BL602/BL604 RISC-V WiFi & Bluetooth 5.0 LE SoC will sell at ESP8266 price point

BL602 BL604 RISC-V WiFI & Bluetooth SoC

Hisilicon Hi3861 may be the first RISC-V WIFI SoC we’ve reported on, but due to political uncertainties and security concerns, supplies may not be available outside of China. So alternatives are welcomed, and Nanjing-based Bouffalo Lab (not a typo, 博流智能科技 in Chinese) has recently introduced BL602 and BL604 32-bit RISC-V WiFi and Bluetooth LE SoC for low-power IoT applications that are supposed to compete against ESP8266 in terms of price but with higher performance and additional features. The BL602 will also be integrated into an upcoming Sipeed Longan-series board, and potentially a new IoT board from Pine64. BL602 / BL604 key features & specifications: MCU subsystem – 32-bit RISC-V CPU with FPU with dynamic frequency from 1MHz to 192MHz, L1 cache Memory – 276KB SRAM on-chip Storage 128KB ROM, 1Kb eFuse, and optional Embedded Flash on-chip XIP QSPI flash support  Wireless Wi-Fi 4 – 802.11 b/g/n @ 2.4 GHz Bluetooth […]

Sipeed Maix Amigo is a Portable 64-bit RISC-V AI Development Kit with Display and Cameras

Sipeed Maix Amigo

Earlier this year, Seeed Studio introduced Wio Terminal a portable Arduino devkit with an LCD display, and expansion connectors and headers. The company is now selling a similar looking devkit but for different applications with Sipeed Maix Amigo portable 64-bit RISC-V development kit powered by Kendryte K210 RISC-V AI processor and equipped with an LCD display, two cameras, a few buttons, and several I/O headers and Grove connectors. Sipeed Maix Amigo specifications: SoC – Kendryte K210 Dual-core 64-bit RISC-V (RV64GC) processor with FPU @ 400 MHz (overclockable to 500MHz), 8MB SRAM, built-in AI accelerators for video and audio Storage – 16MB Flash, MicroSD card slot up Display – 3.5-inch TFT capacitive touch screen display with 480×320 resolution Camera VGA front-facing camera up to 30 fps (GC0328 sensor) VGA rear camera up to 60 fps (OV7740 sensor) Audio – Build-in microphone, optional 6-mic array USB – 1x USB Type-C port for […]

Sipeed TANG Hex is a Low-Cost Xilinx Zynq-7020 Arm FPGA Board

Sipeed TANG Hex

Last year, Sipeed launched a $5 FPGA board called Sipeed Tang and based on an entry-level Gowin GW1N-1-LV FPGA. But I had not noticed the company had also worked on a more powerful, yet still low-cost Xilinx Zynq-7020 board in a business card form factor not too dissimilar from the Raspberry Pi model B form factor. Meet Sipeed TANG Hex. So far a low-cost Zynq-7010 or Zynq-7020 board met you had to spend $99 to $199 with products such as MyIR Z-Turn and Digilent PYNQ-Z1. But Sipeed Tang HEX can be purchased for as little as $73 shipping on Aliexpress,  or 439 RMB ($62) on Taobao for people based in mainland China. It might be tempting to get a low-cost board to get started, but is it worth it? Read on to find out. Sipeed TANG Hex specifications: SoC – Xilinx Zynq-7020 (XC7Z020-1CLG484) dual-core Arm Cortex-A9 processor and FPGA with […]

Sipeed MaixCube is a Fully Integrated AI Development Platform Powered by Kendryte K210 RISC-V SoC

MaixCube All-in-one K210 Development Platform

Sipeed has made several boards and kits based on Kendryte K210 RISC-V processor for low-power AI workloads such as face detection or object recognition including Maixduino board and Grove AI HAT that ship with camera and display. The company has now come up with MaixCube all-in-one development platform that houses Sipeed M1 module, a display, a camera, and a battery into a plastic case that’s somewhat similar to MStack M5StickV but with a larger display, and variations in the form factor and features. Sipeed MaixCube specifications: SoC – Kendryte K210 dual-core 64-bit RISC-V processor @ 400 MHz (overclockable to 600 MHz) with FPU, 8MB SRAM, KPU AI accelerator, APU audio processor, and FFT accelerator Storage – 128 Mbit flash, MicroSD card slot Display – 1.3″ TFT screen with 240×240 resolution Camera – OV7740 sensor (VGA camera) Audio – Built-in microphone, external speakers support; ES8374 audio codec USB – 1x USB […]

How to Build & Run Linux on Kendryte K210 RISC-V NOMMU Processor

RISCV64 NOMMU Menuconfig

A few months ago, we wrote that Western Digital was working on Linux & BusyBox RISC-V NOMMU, and managed to boot a minimal Linux OS on Kendryte K210 powered Sipeed Maix Go board. RISC-V NOMMU support was scheduled for Linux 5.5, and now that the new kernel has been released, Damien Le Moal has pushed the code allowing to build Linux and a busybox based roofs for RISC-V 64-bit NOMMU platforms using buildroot. I could start the build following the instructions on Github, but it failed as a Linux 5.6 RC1 tarball was missing. But I noticed “Vowstart” picked up on Damien’s work, and wrote detailed instructions. So let’s try the build out using a machine running Ubuntu 18.04. We’ll have to make sure dependencies are installed first:

Then we can retrieve the source code and do some preparations (e.g. extract Linux 5.6 RC1 tarball):
