| Overview |
| ******** |
| |
| VOICE-RA4E1 is an edge voice recognition evaluation kit designed to be used by Ecosystem Partners, |
| Application Engineers, Field Application Engineers, and for Business Development opportunities. The |
| primary purpose is to evaluate the functionality of projects developed by Ecosystem Partners, and to |
| facilitate the development of additional partner projects. The kit design to use the RA4E1 MCU with QFN |
| 48pin package as the core logic device, with QSPI flash, OPAMP and power devices chosen from the |
| Renesas product portfolio. |
| |
| The MCU in this series incorporates a high-performance Arm Cortex®-M33 core running up to |
| 100 MHz with the following features: |
| |
| **MCU Native Pin Access** |
| |
| - R7FA4E10D2CNE MCU (referred to as RA MCU) |
| - 100 MHz, Arm® Cortex®-M33 core |
| - 512 KB Code Flash, 8 KB Data Flash, 128 KB SRAM |
| - 48 pins, LQFP package |
| - MCU current measurement point for precision current consumption measurement |
| - Multiple clock sources - Low-precision (~1%) clocks are available internal to the RA MCU. |
| |
| **Kit Peripheral Features** |
| |
| Following is a list of the specific features that have been implemented: |
| |
| - QSPI: One QSPI flash memory device, Dialog AT25SF641B-MHB-T, 64M-bit (8MB). |
| - PMOD: 1 Digilent PMOD connectors, supporting UART, SPI and I2C configurations. |
| - Microphones: 1 I2S MEMS digital microphones and 2 MEMS analog microphones, distance between |
| each pair of microphones is 50mm which is suitable for beamforming applications. |
| - Audio out: One stereo audio headphone jack supporting mono output on both channels. |
| - LEDs: Five LEDs, D2 (Red), D3 (Green) and D4 (Blue) configurable by user, D5 (Blue) as a 3.3V power |
| indicator, D8(Green) as a JLOB (J-LINK on board) indicator. |
| - Buttons: One RESET button (S2), and one USER button (S1). |
| - Debug: J-Link On-Board debug interface, supporting JTAG or SWD debug port. |
| - USB: Micro USB-B (J6) for power input and J-Link On-Board function, USB-C (J1) for power input and |
| RA4E1 USB Full Speed port as a USB device. |
| - Form Factor: 7.5 x 6 cm |

| |
| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Applications for the ``voice_ra4e1`` board 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 VOICE-RA4E1 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 `VOICE-RA4E1 - Engineering 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: R7FA4E10D |
| * 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 |
