| |
| Overview |
| ******** |
| |
| The EK-RA8M1 is an Evaluation Kit for Renesas RA8M1 MCU Group which is the first |
| 32-bits MCUs based on new Arm Cortex-M85. The kit offer multiple external interface |
| and peripherals set optimized on board allows user to seamlessly evaluate the features |
| of the RA8M1 MCU and develop embedded system application in various field. |
| |
| The key features of the EK-RA8M1 board are categorized in three groups as follow: |
| |
| **MCU Native Pin Access** |
| |
| - 480MHz Arm Cortex-M85 based RA8M1 MCU in 224 pins, BGA package |
| - Native pin acces througgh 2 x 50-pin, and 2 x 40-pin male headers |
| - MCU current measurement points for precision current consumption measurement |
| - Multiple clock sources - RA8M1 MCU oscillator and sub-clock oscillator crystals, |
| providing precision 20.000MHz and 32,768 Hz refeence clocks. |
| Additional low precision clocks are avaialbe internal to the RA8M1 MCU |
| |
| **System Control and Ecosystem Access** |
| |
| - USB Full Speed Host and Device (micro-AB 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) |
| - Debug in (ETM, SWD and JTAG) |
| - Debug out (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 (I2C/I3C) connectors |
| - One SparkFun Qwiic connector |
| - Two Digilent Pmod (SPI, UART and I2C/I3C) connectors |
| - Arduino (Uno R3) connector |
| - MikroElektronika mikroBUS connector |
| |
| - MCU boot configuration jumper |
| |
| **Special Feature Access** |
| |
| - Ethernet (RJ45 RMII interface) |
| - USB High Speed Host and Device (micro-AB connector) |
| - 512 Mb (64 MB) External Octo-SPI Flash (present in the MCU Native Pin Access area of the EK-RA8M1 board) |
| - CAN FD (3-pin header) |

| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``ek_ra8m1`` 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 |
| |
| Flashing |
| ======== |
| |
| Program can be flashed to EK-RA8M1 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-RA8M1 - 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: R7FA8M1AH |
| * 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 |
