Onboard debugger
This product has the onboard debugger circuit, J-Link On-Board (hereinafter called “J-Link-OB”). When you write a program, open the JP3 and connect the USB connector(CN13) on CPU board to PC with USB cable. J-Link-OB operates as debugger equivalent to J-Link. If connecting from flash programing tool (e.g. J-Flash Lite by SEGGER), set the type of debugger (tool) to “J-Link”

Programming and Debugging
The mck_ra8t2 board supports the runners and associated west commands listed below.
| flash | debug | debugserver | rtt | attach | |
|---|---|---|---|---|---|
| jlink | ✅ (default) | ✅ (default) | ✅ | ✅ | ✅ |
Applications for the mck_ra8t2 board configuration can be
built, flashed, and debugged in the usual way. See
Building an Application and Run an Application for more details on
building and running.
Here is an example for the Hello World application on CM85 core.
# From the root of the zephyr repository
west build -b mck_ra8t2/r7ka8t2lfecac/cm85 samples/hello_world
west flash
Open a serial terminal, reset the board (push the reset switch S1), and you should see the following message in the terminal:
***** Booting Zephyr OS v4.2.0-xxx-xxxxxxxxxxxxx *****
Hello World! mck_ra8t2/r7ka8t2lfecac/cm85
Flashing
Program can be flashed to MCB-RA8T2 via the on-board SEGGER J-Link debugger. SEGGER J-link’s drivers are available at https://www.segger.com/downloads/jlink/
To flash the program to board
Connect to J-Link OB via USB port to host PC
Make sure J-Link OB jumper is in default configuration as describe in MCB-RA8T2 - User’s Manual
Execute west command
west flash -r jlink
