RA8D1 Vision Board

Overview

The RA8D1-VISION-BOARD, based on the Renesas Cortex-M85 architecture RA8D1 chip, offers engineers a flexible and comprehensive development platform, empowering them to explore the realm of machine vision more deeply.

Key Features

  • Arm Cortex-M85

  • 480MHz frequency, on-chip 2Mb Flash, 1Mb SRAM

  • 32Mb-SDRAM; 8Mb-QSPI Flash

  • MIPI-DSI; RGB666; 8bit Camera

  • On-board DAP-LINK debugger with CMSIS-DAP

  • Raspberry Pi Interface

More information about the board can be found at the RA8D1-VISION-BOARD website [1].

Default Zephyr Peripheral Mapping:

The RA8D1-VISION-BOARD board features a On-board CMSIS-DAP debugger/programmer. Board is configured as follows:

  • UART9 TX/RX : P209/P208 (CMSIS-DAP Virtual Port Com)

  • LED0 : P102

  • LED1 : P106

  • LED2 : PA07

  • USER BUTTON : P907

Programming and Debugging

The ra8d1_vision_board board supports the runners and associated west commands listed below.

flash debug

Applications for the ra8d1_vision_board board can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application 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 RA8D1-VISION-BOARD 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 RA8D1-VISION-BOARD via the on-board DAP-LINK debugger.

Linux users: to fix the permission issue, simply add the following udev rule for the CMSIS-DAP interface:

$ echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="0416", ATTR{idProduct}=="7687", MODE:="666"' > /etc/udev/rules.d/50-cmsis-dap.rules

To flash the program to board

  1. Connect to DAP-LINK via USB port to host PC

  2. Execute west command

    west flash

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b ra8d1_vision_board samples/hello_world
west debug
