Build and Flash Guideline

For required tool and environment setup to develop Zephyr, please check: Getting started guide

1. Build Command

west build -p always -b rcar_ironhide_x5h/r8a7800/r52 samples/hello_world

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: How to flash bootloaders to the Ironhide board and replace Test Bare metal RT images with Zephyr images for corresponding cores.

Hardware connection for UART samples

• echo_bot (samples/drivers/uart/echo_bot):

  • Hardware configuration: refer to default UART connection.
  • Build command:
    • west build -p always -b rcar_ironhide_x5h/r8a7800/r52 samples/drivers/uart/echo_bot

• zTest uart_basic_api (tests/drivers/uart/uart_basic_api):

  • Hardware configuration: refer to default UART connection.
  • Build command:
    • west build -p always -b rcar_ironhide_x5h/r8a7800/r52 tests/drivers/uart/uart_basic_api
