Wio Lite RISC-V¶

Hardware¶

Platform GigaDevice GD32V: The GigaDevice GD32V device is a 32-bit general-purpose microcontroller based on the RISC-V core with an impressive balance of processing power, reduced power consumption and peripheral set.

Configuration¶

Please use wio_lite_risc-v ID for board option in “platformio.ini” (Project Configuration File):

[env:wio_lite_risc-v]
platform = gd32v
board = wio_lite_risc-v

You can override default Wio Lite RISC-V settings per build environment using board_*** option, where *** is a JSON object path from board manifest wio_lite_risc-v.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:wio_lite_risc-v]
platform = gd32v
board = wio_lite_risc-v

; change microcontroller
board_build.mcu = GD32VF103CBT6

; change MCU frequency
board_build.f_cpu = 108000000L

Uploading¶

Wio Lite RISC-V supports the next uploading protocols:

• altera-usb-blaster

• gd-link

• jlink

• rv-link

• serial

• sipeed-rv-debugger

• um232h

Default protocol is serial

You can change upload protocol using upload_protocol option:

[env:wio_lite_risc-v]
platform = gd32v
board = wio_lite_risc-v

upload_protocol = serial

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Wio Lite RISC-V does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
