R Car X5H Ironhide Sample and Demo hardware configuration - renesas/zephyr GitHub Wiki

Followings are hardware connection and test samples for the R-Car X5H Ironhide board.

Default UART connection

Physical Interface Location Software Interface Converter Further Information
CN44_USB_PORT (USB 2.0 Micro-B) CPU Board SCIF1/HSCIF0 FT2232H-56Q Default Zephyr serial on SCIF1/ Linux serial on HSCIF0

The default UART port can be accessed by connecting a USB 2.0 Micro-B cable to the CN44_USB_PORT on the board.

Open a serial terminal, such as Tera Term or minicom, with the following settings:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

Build and Flash Guideline

For required tool and environment setup to develop Zephyr, please check: System Requirements

1. Build Command

west build -p always -b rcar_ironhide_x5h/r8a7800/r52 <application_path>

2. Flash Command

At this time, no direct flashing method is officially supported by this Zephyr port. However, it is possible to load the Zephyr binary via specific method.
