National Core RISC-V Hall: front-line engineer evaluation summary, official learning and development resources (under construction and update)
[Copy link]
* Updated: August 11, 2021
At the first RISC-V China Summit held this year , we saw many familiar domestic chip manufacturers. It can be said that domestic chip companies are very active in the layout of RISC-V . The RISC-V open source architecture has been actively practiced and explored by the industry, and is expected to become a major trend in global chip innovation. The future is both promising and unknown. At present, we can follow the evaluation and resource sorting of the front-line engineers of Tanzi to take a closer look at the chip situation of RISC-V core.
GigaDevice GD32VF103 Series
On August 22, 2019, the world's first GD32V series 32-bit general-purpose MCU products based on the RISC-V core were launched, providing complete tool chain support from chips to program code libraries, development kits, design solutions, etc., and continuing to build a RISC-V development ecosystem.

Qinheng general MCU CH32V103, CH57X series with built-in BLE, etc.
In 2017, we began to pay attention to and study the 32-bit MCU architecture of the RISC-V open source instruction set, and optimized it for fast interrupt response and high-bandwidth data DMA. We have formed multiple versions of RISC-V processors that focus on low power consumption or high performance. In 2019, we launched the CH32V103 microcontroller based on the RISC-V3A processor and the CH57X series with embedded BLE low-power Bluetooth. In early 2020, we launched the high-throughput CH56X series with 128-bit data width and dual-layer DMA architecture. We have now expanded to include floating-point V4F, streamlined V2A, enhanced V3A/V4A/V4B/V4C and other core products. Official RISC-V MCU product page: http://special.wch.cn/zh_cn/RISCV_MCU_Index/

RVB-ICE, RVB-D1, RVB2601
As one of the earliest companies in China to develop RISC-V technology, Pingtou Ge has successively launched a number of RISC-V processor products such as Xuantie 902, 906, 907 and 910. At the 2021 Alibaba Cloud Summit, Pingtou Ge, a semiconductor company under Alibaba, launched three RISC-V development boards: RVB-ICE, RVB-D1, and RVB2601, which are suitable for high-performance, high-energy-efficiency, and low-power scenarios, respectively, and can support Android, Linux, AliOS Things and other operating systems. The three development boards are now open to developers around the world. Official RISC-V theme page: https://occ.t-head.cn/community/risc_v

Zhongke Bluexun and RT-Thread AB32VG1 RISC-V evaluation board
China's leading RISC-V IoT chip company, Zhongke Bluexun, has started a strategic partnership with RT-Thread. Zhongke Bluexun will natively carry the RT-Thread operating system on its full range of RISC-V chips, and Ruiside Technology will provide Zhongke Bluexun with all-round strong support in technology, community promotion, etc. There is basically very little development information available on Zhongke Bluexun's official website, and the main development information comes from RT-Thread.

BearPi-HM Nano | Huawei HiSilicon Hi3861
BearPi- HM Nano is a HarmonyOS development board specially designed by BearPi for HarmonyOS system. The main controller is WiFi SOC Hi3861 which is based on RISC-V architecture. Although Huawei did not mention it in the manual, or they put the focus of publicity on HarmonyOS, we, the famous detective electronic engineer cruelfox, found it.
