This article describes specifics for the ST NUCLEO-WBA55CG evaluation board.
Preparing for J-Link
- Connect the J-Link to the following pins (nTRST, TDI and TDO are only necessary for connecting with JTAG, if you use SWD you don't need them):
| J-Link Pin | Connector | Pin | Name |
|---|---|---|---|
| VTref | CN3 | 12 | V_TARGET |
| GND | CN3 | 8 | GND |
| nTRST | CN4 | 11 | PB4 |
| TDI | CN4 | 15 | PA15 |
| TMS/SWDIO | CN3 | 9 | PA13 |
| TCK/SWCLK | CN3 | 11 | PA14 |
| TDO | CN4 | 13 | PB3 |
| Reset | CN3 | 14 | NRST |
- Set Jumper JP1 to 9-10 (VBUS)
- Set Jumper JP4
- Power the board via CN15 (USB-C)
- Verify the Connection with e.g. J-Link Commander. The output should look as follows:
Example Project
The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the ST NUCLEO-WBA55CG.
It is a simple Hello World sample linked into the internal flash.
