EK-RA8D1 Kit

This topic provides board-specific information about Renesas' EK-RA8D1.

Board features

  • R7FA8D1BHECBD MCU featuring ARM® Cortex®-M85, 2 MB Flash, 1 MB SRAM
  • 4.5” 480x854 LCD Touch Display
  • 64 MB SDRAM
  • 64MB External Octo-SPI Flash

Supported color depths

The reference port for this board supports 16bpp color depth. See QUL_COLOR_DEPTH and Color depth for more information.

Building applications with prebuilt Qt Quick Ultralite libraries

  1. Open the CMake project file for the example you want to build.
  2. In the Configure Project window:
    1. Select the kit you created earlier. For example, Qt for MCUs 2.10.0 - Desktop 32bpp.
    2. Select Configure Project.

{MCU project configuration}

Once the project is configured, select Run or press Ctrl+r on your keyboard to build and flash the binary to the target.

Reading debug messages

By default, log data is redirected to JLink CDC UART Port (USB COM port).

Debugging

Renesas e2 studio

Renesas e2 studio lets you debug a project using a custom configuration.

  1. Create a Bare Metal - Minimal project for EK-RA8D1.
  2. Build the project.
  3. Copy the Qt Quick Ultralite .elf file into the Debug folder of the e2 studio project.
  4. Take a copy of the original .sbd file and rename it with same name as the Qt Quick Ultralite .elf file.
  5. Select Run from the top menu.
  6. Select Debug Configurations....
  7. Select Renesas GDB Hardware Debugging.
  8. Set the Qt Quick Ultralite .elf to the C/C++ Application:.
  9. Select Apply and Close.
  10. Select Launch in 'Debug' mode.
