@brief Support for the GD32VF103C-START board
|

@author Marian Buschsieweke
|
||||
|
||||
## Overview
|
||||
|
||||
The GD32VF103C-START development board is an official starter kit by GigaDevice
|
||||
for the GD32VF103CBT6 MCU, despite the lack of official documentation. It
|
||||
featrures:
|
||||
|
||||
- GD32VF103CBT6 RISC-V MCU @108MHz
|
||||
- On-Board GD-Link Programmer/Debugger (middle mini-USB connector)
|
||||
- USB-OTG (left mini-USB connector)
|
||||
- Integrated USB to UART bridge (right mini-USB connector)
|
||||
- 1 user LED
|
||||
- 1 user Button
|
||||
- 1 reset button
|
||||
- Arduino UNO compatible pin headers (except ISP header)
|
||||
|
||||
|
||||
|
||||
@warning The analog pins are labeled A1 - A6 rather than A0 - A5, as would
|
||||
be the correct Arduino naming. The Arduino pin mapping uses the
|
||||
correct Arduino naming, so that apps written for other boards
|
||||
expecting Arduino UNO compatible shields remain compatible.

||||

|
||||
|
||||
## Flashing
|
||||
|
||||
@warning Flashing seems to fail with some Arduino UNO compatible boards
|
||||
attached. Remove them and try again.
|
||||
|
||||
By default, flashing is done via OpenOCD using the GD-Link programmer/debugger
|
||||
using:
|
||||
|
||||
```
|
||||
make BOARD=gd32vf103c-start -C path/to/app flash
|
||||
```
|
||||
|
||||
It is also possible to flash via DFU-Util:
|
||||
|
||||
1. Connect a mini USB cable to the USB connector labeled OTG.
|
||||
2. Power the board (e.g. by connecting a second mini USB cable to the GD-Link
|
||||
programmer/debugger, even though we won't use it)
|
||||
3. Enter the DFU bootloader by placing the jumper on JP4 (below BOOT) in
|
||||
position H. Press the reset button afterwards.
|
||||
4. Run `make BOARD=gd32vf103c-start PROGRAMMER=dfu-util -C path/to/app flash`
|
||||
5. Restore the JP4 jumper to position L. Afterwards press the reset button
|
||||
again
|
||||
|
||||
## Connecting to the Serial Output
|
||||
|
||||
By default RIOT's uses UART for `stdio`. To access that, connect a mini USB
|
||||
cable to the connector labeled "USART". In addition a jumper needs to be
|
||||
placed on JP2 in the "Usart" position; otherwise RIOT's TXD is not connected
|
||||
to the RXD of the integrated USB UART bridge. Afterwards just run:
|
||||
|
||||
```
|
||||
make BOARD=gd32vf103c-start -C path/to/app term
|
||||
```
|
||||
|
||||
Alternatively, `stdio_cdc_acm` can be used. In this case the mini USB cable
|
||||
needs to be connected to the USB connector labeled OTG.
|
||||
|
||||
@note It is safe to keep the jumper at JP2 in "Usart" position or even
|
||||
remove the jumper with RIOT. PA9 is still used as UART/TXD and VBUS
|
||||
sensing is disabled anyway.
