The WIZnet W55RP20-EVB-Pico is a W55RP20 evaluation board.
Setting up with J-Link
The W55RP20-EVB-Pico comes with an external SWD debug connector. To set the board up with J-Link, the following steps are required:
- Solder a 3-pin header to the debug connector pads.
- Solder a pin strip to the GPIO pads of the evaluation board. The relevant pad is 3V3.
- Connect the J-Link to the evaluation board, using jumper wires as follows:
| Name | J-Link Pin | Signal |
|---|---|---|
| SWCLK | 9 | SWCLK |
| GND | 4 | GND |
| SWDIO | 7 | SWDIO |
| 3V3 | 1 | VTref |
Note: For a more reliable, simpler solution, the SEGGER Flying Wire Adapter is recommended.
- Power the board via the USB port
- Verify the Connection with J-Link Commander. The output should look as follows:
