| RA6M2 Evaluation Kit |
| #################### |
| |
| Overview |
| ******** |
| |
| The Renesas RA6M2 microcontroller is the entry point to the Renesas RA6 product series |
| for applications that require a high-performance Arm® Cortex®-M4 core at a very attractive |
| price point. The RA6M2 is suitable for IoT applications requiring security, large embedded |
| RAM and low power consumption. |
| |
| The key features of the EK-RA6M2 board are categorized in three groups as follow: |
| |
| **MCU Native Pin Access** |
| |
| - 120MHz Arm Cortex-M4 based RA6M2 MCU in 144 pins, LQFP package |
| - Native pin access through 4 x 40-pin male headers |
| - MCU and USB current measurement points for precision current consumption measurement |
| - Multiple clock sources - RA6M2 MCU oscillator and sub-clock oscillator crystals, |
| providing precision 12.000 MHz and 32,768 Hz reference clock. |
| Additional low precision clocks are avaialbe internal to the RA6M2 MCU |
| |
| **System Control and Ecosystem Access** |
| |
| - USB Full Speed device |
| - 5V input through USB debug |
| |
| - Three Debug modes |
| |
| - Debug on-board (SWD) |
| - Debug in (SWD and JTAG) |
| - Debug out (SWD) |
| |
| - User LEDs and buttons |
| |
| - One User LEDs |
| - One User buttons |
| - One Reset button |
| |
| - Three most popular ecosystems expansions |
| |
| - Two Digilent Pmod (SPI and UART) connectors |
| - Arduino (Uno R3) connector |
| - MikroElektronika mikroBUS connector |
| |
| - MCU boot configuration jumper |
| |
| **Special Feature Access** |
| |
| - USB Full Speed Host and Device (micro-AB connector) |

| Programming and Debugging |
| ************************* |
| |
| Applications for the ``ek_ra6m2`` board target 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. |
| |
| Flashing |
| ======== |
| |
| Program can be flashed to EK-RA6M2 via the on-board SEGGER J-Link debugger. |
| SEGGER J-link's drivers are avaialbe at https://www.segger.com/downloads/jlink/ |
| |
| To flash the program to board |
| |
| 1. Connect to J-Link OB via USB port to host PC |
| |
| 2. Make sure J-Link OB jumper is in default configuration as describe in `EK-RA6M2 - User's Manual`_ |
| |
| 3. Execute west command |
| |
| .. code-block:: console |
| |
| west flash -r jlink |
| |
| Debugging |
| ========= |
| |
| 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: |
| |
| * Target Device: R7FA6M2AD |
| * Target Interface: SWD |
| * Target Interface Speed: 4 MHz |
| * Host Interface: USB |
| * Program File: <path/to/your/build/zephyr.elf> |
| |
| **Note:** It's verified that we can debug OK on Segger Ozone v3.30d so please use this or later |
| version of Segger Ozone |
