longan nano #

The examples for this Microcontroller do not work any more (framework hell as always) and you get an error message:

HTTPClientError: You do not have permission for this request

Download dependencies elsewhere #

Download everything with gd32.*linux in its name from sourceforge and place it in a new subfolder packages/ of a sample platformio-project, recognizable by a platformio.ini in its root.

Extract and rename files #

Extract the (four) packages and remove from their names everything including and after -linux.

The platformio.ini #

Replace the platformio.ini with this content:

[env:sipeed-longan-nano]
platform = gd32v
board = sipeed-longan-nano
framework = gd32vf103-sdk
platform_packages = framework-gd32vf103-sdk @ file://packages/framework-gd32vf103-sdk
                    toolchain-gd32v @ file://packages/toolchain-gd32v
                    tool-openocd-gd32v @ file://packages/tool-openocd-gd32v
                    tool-gd32vflash @ file://packages/tool-gd32vflash
upload_protocol = dfu

Test if it works:

platformio run  # or `pio run`

Upload the .bin:

pio run --target upload

Thanks especially to the following individuals, who spend a lot of time to figure out how it works at the moment. This page summarizes the entire procedure to make it easier for others to follow.
