4 years ago Problem solved: in fact the Sipeed Longan Nano I got is the "lite" version = 64KB Flash, 20KB SRAM. All works well now by simply changing in platformio.ini: board = sipeed-longan-nano-lite I hope this helps other users of the same model!
Having bought a Sipeed Longan Nano RISC-V GD32VF103CBT6 MCU Development Board, I have installed Visual Studio Code with platformio add-on. Drivers GD32 MCU Dfu Drivers_v1.0.1.2316 for Windows 10. Then loaded "arduino-blink", compiled (one button Build), with no issues. Mention here platformio.ini lines: [env:sipeed-longan-nano] platform = gd32v framework = arduino board = sipeed-longan-nano monitor_speed = 115200 upload_protocol = dfu
The board was set in burning mode: the Device Manager shows in USB devices: GD32 Device in DFU mode. Download, with messages: Opening DFU capable USB device...

Now comes the question: After Reset, NO sign of blink (the factory 4 colors blink went off). Moreover the display went dark. Being the first time I try to use this board, I would appreciate a suggestion to make work the first code!
