CEC1702 clicker
The Mikroe CEC1702 clicker board does not come with an external debug connector. Therefore in order to use an external debug probe like the J-Link the Mikroe CEC1702 clicker board needs to be manually setup:
- Populate the header J1 (Marked red in attached picture) with a 2 x 5 pin header by soldering
- Connect your JLink debug probe with e.g. jumper wires with header J1 the following way (Pin 1 is marked with a white dot):
Pin header J1 | J-Link |
---|---|
Pin 1 (VCC-3.3V) | Pin 1 (VTref) |
Pin 9 (GND) | Pin 4 (GND) |
Pin 7 (SHD_CS0) | Do not connect |
Pin 2 (JTAG_TMS) | Pin 7 (TMS/SWDIO) |
Pin 4 (JTAG_CLK) | Pin 9 (TCK/SWCLK) |
Pin 6 (JTAG_TDO) | Pin 13 (TDO/SWO) |
Pin 8 (JTAG_TDI) | Pin 5 (TDI) |
Pin 10 (JTAG_RST) | Pin 15 (RESET) |
Note: The CEC1702 MCU is only connected via SWD on this particular board even though the signals are named "JTAG" in the schematics so make sure to connect through SWD.
