This article describes specifics for the Geehy G32R430 TinyBoard evaluation board.
Preparing for J-Link
- Separate the included GeehyLink CMSIS-DAP probe from the main G32R430 TinyBoard evaluation board by breaking it off at the three mousebites.
- Connect the J-Link to the following pins on connector J17:
| J-Link Pin | Connector | Pin | Name |
|---|---|---|---|
| VTref | J1 | 3V3 | 3.3 V supply voltage |
| GND | J1 | GND | Ground |
| TMS/SWDIO | J1 | SWDIO | SWD I/O signal |
| TCK/SWCLK | J1 | SWDIO | SWD clock signal |
| RESET | J1 | RESET | Reset signal |
- Power the board by connecting a 3.3 V supply voltage between the GND and 3V3 pins on connector J17. You can use the broken off GeehyLink for generating an appropriate voltage by connecting it to a USB-C power supply.
- Verify the Connection with e.g. J-Link Commander. The output should look as follows:
