| Overview |
| ******** |
| |
| The EK-RA6E2, an Evaluation Kit for RA6E2 MCU Group, enables users to |
| seamlessly evaluate the features of the RA6E2 MCU group and develop |
| embedded systems applications using Flexible Software Package (FSP) |
| and e2 studio IDE. The users can use rich on-board features along with |
| their choice of popular ecosystems add-ons to bring their big ideas to life |
| |
| The key features of the EK-RA6E2 board are categorized in three groups as follow: |
| |
| **MCU Native Pin Access** |
| |
| - 200MHz Arm Cortex-M33 based RA6E2 MCU in 64 pins, LQFP package |
| - 256 kB Code Flash, 40 kB SRAM |
| - Native pin access through 2 x 14-pin and 1 x 40-pin male headers |
| - MCU current measurement points for precision current consumption measurement |
| - Multiple clock sources - RA6E2 MCU oscillator and sub-clock oscillator crystals, |
| providing precision 20.000 MHz and 32,768 Hz reference clock. |
| Additional low precision clocks are available internal to the RA6E2 MCU |
| |
| **System Control and Ecosystem Access** |
| |
| - USB Full Speed Host and Device (micro-AB connector) |
| - Three 5V input sources |
| |
| - USB (Debug, Full Speed) |
| - External power supply (using surface mount clamp test points and J31 through holes) |
| |
| - Three Debug modes |
| |
| - Debug on-board (SWD) |
| - Debug in (SWD) |
| - Debug out (JTAG, SWD) |
| |
| - User LEDs and buttons |
| |
| - Three User LEDs (red, blue, green) |
| - Power LED (white) indicating availability of regulated power |
| - Debug LED (yellow) indicating the debug connection |
| - Two User buttons |
| - One Reset button |
| |
| - Five most popular ecosystems expansions |
| |
| - Two Seeed Grove system (I3C/Analog) connectors |
| - One SparkFun Qwiic connector |
| - Two Digilent Pmod (SPI and UART) connectors |
| - Arduino (Uno R3) connector |
| - MikroElektronika mikroBUS connector |
| |
| - MCU boot configuration jumper |
| |
| **Special Feature Access** |
| |
| - 16 Mb (128 Mb) External Quad-SPI Flash |
| - CAN (3-pin header) |

| |
| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Applications for the ``ek_ra6e2`` 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-RA6E2 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 |
| |
| 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-RA6E2 - 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: R7FA6E2BB |
| * 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 |
