| Overview |
| ******** |
| |
| The EK-RA8P1 is an Evaluation Kit for Renesas RA8P1 MCU Group which integrates multiple series of software-compatible |
| Arm®-based 32-bit cores that share a common set of Renesas peripherals to facilitate design scalability and efficient |
| platform-based product development. |
| |
| The MCU in this series incorporates a high-performance Arm® Cortex®-M85 core running up to 1 GHz and Arm® |
| Cortex®-M33 core running up to 250 MHz with the following features: |
| |
| - Up to 1 MB MRAM |
| - 2 MB SRAM (256 KB of CM85 TCM RAM, 128 KB CM33 TCM RAM, 1664 KB of user SRAM) |
| - Arm® Ethos™-U55 NPU |
| - Octal Serial Peripheral Interface (OSPI) |
| - Layer 3 Ethernet Switch Module (ESWM), USBFS, USBHS, SD/MMC Host Interface |
| - Graphics LCD Controller (GLCDC) |
| - 2D Drawing Engine (DRW) |
| - MIPI DSI/CSI interface |
| - Analog peripherals |
| - Security and safety features |
| |
| **MCU Native Pin Access** |
| |
| - 1 GHz Arm Cortex-M85 and 250 MHz Arm Cortex-M33 based RA8P1 MCU in 289 pins, BGA package |
| - Native pin access through 2 x 20-pin, and 2 x 40-pin headers (no populated) |
| - Camera Expansion connector (present on the underside of the EK-RA8P1 board) |
| - 2-Lane MIPI Display connector (present on the underside of the EK-RA8P1 board) |
| - Parallel graphics display interface connector |
| - MCU current measurement points for precision current consumption measurement |
| - Multiple clock sources - RA8P1 MCU oscillator and sub-clock oscillator crystals, |
| providing precision 24.000 MHz and 32,768 Hz reference clocks. |
| Additional low precision clocks are available internal to the RA8P1 MCU |
| |
| **System Control and Ecosystem Access** |
| |
| - USB Full Speed Host and Device (USB-C connector) |
| - Four 5V input sources |
| |
| - USB (Debug, Full Speed, High Speed) |
| - External power supply (using surface mount clamp test points and power input vias) |
| |
| - Three Debug modes |
| |
| - Debug on-board (SWD and JTAG) |
| - Debug in (ETM, SWD, SWO and JTAG) |
| - Debug out (SWD, SWO, and JTAG) |
| |
| - 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 |
| - Ethernet LEDs (amber, yellow, green) |
| - Two User buttons |
| - One Reset button |
| |
| - Five most popular ecosystems expansions |
| |
| - Two Seeed Grove system (I2C/I3C/Analog) connectors (not populated) |
| - One SparkFun Qwiic connector (not populated) |
| - Two Digilent Pmod (SPI, UART and I2C) connectors |
| - Arduino (Uno R3) connector |
| - MikroElektronika mikroBUS connector (not populated) |
| |
| - MCU boot configuration jumper |
| |
| **Special Feature Access** |
| |
| - Ethernet (RJ45 RGMII interface) |
| - USB High Speed Host and Device (USB-C connector) |
| - 512 Mb (64 MB) External Octo-SPI Flash (present in the MCU Native Pin Access area of the EK-RA8P1 board) |

| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``ek_ra8p1`` 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. |
| |
| Here is an example for the :zephyr:code-sample:`hello_world` application on CM85 core. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: ek_ra8p1/r7ka8p1kflcac/cm85 |
| :goals: flash |
| |
| Open a serial terminal, reset the board (press the S3 button), and you should |
| see the following message in the terminal: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS v4.2.0-xxx-xxxxxxxxxxxxx ***** |
| Hello World! ek_ra8p1/r7ka8p1kflcac/cm85 |
| |
| Flashing |
| ======== |
| |
| Program can be flashed to EK-RA8P1 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 described in `EK-RA8P1 - User's Manual`_ |
| |
| 3. Execute west command |
| |
| .. code-block:: console |
| |
| west flash -r jlink |
