The CEC1702 clicker is a compact development board with a Microchip CEC1702 - a 32-bit ARM® Cortex™ -M4 Processor Core, designed for cryptographic operations. For further information please visit: https://shop.mikroe.com/clicker-cec1702

Connecting J-Link to the clicker board

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:

  1. Populate the header J1 (Marked red in attached picture) with a 2 x 5 pin header by soldering
  2. Connect your JLink debug probe with e.g. jumper wires with header J1 like described in the following table and attached connector picture (Pin 1 is marked with a white dot):
Pin header J1 J-Link
Pin 1 (RED) Pin 1 (VTref)
Pin 2 (GREEN) Pin 7 (SWDIO)
Pin 3 Do not connect, leave open
Pin 4 (YELLOW) Pin 9 (SWCLK)
Pin 5 Do not connect, leave open
Pin 6 Do not connect, leave open
Pin 7 Do not connect, leave open
Pin 8 Do not connect, leave open
Pin 9 (BLACK) Pin 4 (GND)
Pin 10 (BLUE) Pin 15 (RESET)
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.

Board specifics

Flash programming

The CEC1702 does not provide internal (on-chip) flash. On the CEC1702 clicker board there is a serial NOR flash memory (Microchip SST26VF016B) mounted. The CEC1702 boots from this flash. J-Link software version V6.16h or later is needed to program the serial NOR flash.
