Sipeed Longan Nano Lite¶

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 sipeed-longan-nano-lite ID for board option in “platformio.ini” (Project Configuration File):

[env:sipeed-longan-nano-lite]
platform = gd32v
board = sipeed-longan-nano-lite

You can override default Sipeed Longan Nano Lite settings per build environment using board_*** option, where *** is a JSON object path from board manifest sipeed-longan-nano-lite.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:sipeed-longan-nano-lite]
platform = gd32v
board = sipeed-longan-nano-lite

; change microcontroller
board_build.mcu = GD32VF103C8T6

; change MCU frequency
board_build.f_cpu = 108000000L

Uploading¶

Sipeed Longan Nano Lite supports the following 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:sipeed-longan-nano-lite]
platform = gd32v
board = sipeed-longan-nano-lite

upload_protocol = serial

Debugging¶

Debugging - “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).

Sipeed Longan Nano Lite 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.
