Overview
The MCK-RA8T1 is a development kit that enables easy evaluation of motor control using permanent magnet synchronous
motors (brushless DC motors). More detailed information about the features of this toolkit and it's applications can be
found here: MCK-RA8T1 Website_
MCK-RA8T1 kit includes the items below:

MCB-RA8T1 is a CPU board for motor control equipped with RA8T1. Motor control using RA8T1 can be easily realized by using it in combination with a supported inverter board. The RA8T1 MCU can be evaluated using this board alone.
By using a supported communication board, the CPU board can be electrically isolated from the PC for safe motor control evaluation and debugging.
The specifications of the CPU board are shown below:
MCU specifications
480MHz Arm Cortex-M85 based RA8T1 MCU in 224 pins, BGA package
ROM/RAM size: 2MB/1MB
MCU input clock: 24MHz (Generate with external crystal oscillator)
Power supply: DC 5V, select one way automatically from the below:
Connector
Onboard debugger
This product has the onboard debugger circuit, J-Link On-Board (hereinafter called “J-Link-OB”). You can write a program (firmware) of RA8T1 with it.
Hardware

.. note::
For using SDHC module on EK-RA8M1, Connect microSD Card to microSD Socket (CN12)
Programming and Debugging
.. zephyr:board-supported-runners::
Applications for the mcb_ra8t1 board configuration can be
built, flashed, and debugged in the usual way. See
:ref:build_an_application and :ref:application_run for more details on
building and running.
Note: Only support from SDK v0.16.6 in which GCC for Cortex Arm-M85 was available. To build for EK-RA8M1 user need to get and install GNU Arm Embedded toolchain from https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.16.6
Program can be flashed to MCB-RA8T1 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-RA8T1 - User's Manual_
Execute west command
.. code-block:: console
west flash -r jlink
You can use Segger Ozone (Segger Ozone Download_) for a visual debug interface
Once downloaded and installed, open Segger Ozone and configure the debug project like so:
Note: It's verified that debug is OK on Segger Ozone v3.30d so please use this or later version of Segger Ozone
