LCSC GigaDevice GD32VW553 Datasheet - WiFi 6+BLE 5.2, 4 MB, 160Mhz MCU - OpenGD32 Firmware

The GD32VW553 is a GigaDevice Combo Wireless MCU family based on a 32-bit RISC-V core running at up to 160 MHz. GigaDevice announced the official launch on 6 November 2023, with samples and evaluation boards available for request at that time and mass production/delivery scheduled from December 2023.

GigaDevice positions the series for wireless application scenarios including smart home appliances, smart home systems, industrial Internet, and communication gateways. It also describes the family as suitable for budget-constrained scenarios such as office equipment, payment terminals, and other IoT products. GigaDevice separately mentions industrial control interconnection, lighting equipment, and socket panels as application scenarios for the device voltage and high-temperature range.

At time of posting, GD32VW553 is mostly seen on development boards. I don't believe we've identified a commercial product using this MCU yet.

undoubtedly others.

I bought the GD32VW553HMQ6 LCSC board from Ali Express for £5.14 delivered https://www.aliexpress.com/item/1005009723659760.html
It seems to be eligible for Welcome Deal pricing at the moment











I have just opened the packet and am discovering things as I go.

GigaDevice supply an all-in-one programming tool for the GD32VW5

https://www.gd32mcu.com/en/download/7?kw=GD32VW5

The 7z download seems to contain English documentation, xmodem stub files, flash and efuse option xmls

First, a dump of the factory flash content to file. Hold BOOT0 button down (pulls PC08 high) and RST to get into programming mode.

Connect

UART button in GD32 AIO app.


My chip is detected as GD32VW553HMQ6, 4096KB flash and 320KB SRAM, no external flash.

Save full chip flash to file with 'Upload' section (upload to your PC, to a file), after specifying destination file name and location.

At boot, factory firmware from PA06 (UART2_TX) @115200 baud prints:


and from PB15 (UART1_TX) simply:

Now to download (to the GD32) @insmod's OpenGD32VW553 port - the latest development build from https://github.com/openshwprojects/OpenBK7231T_App/actions/runs/26806809717



OpenGD32 boot log from PA06 at 1500000 baud


and AP is seen as expected




The user button on the LCSC is PA0. The LED is PC13.
