EK‐RA8M1 Sample and Demo Hardware configuration - renesas/zephyr GitHub Wiki

Followings are hardware connection and test samples for EK-RA8M1, for more detail on 1st setup hardware connection, please visit EK-RA8M1 - Quick Start Guide and EK-RA8M1 v1 - User's Manual

Default HW configuration

Use Debug On-Board mode: EK-RA8M1 board require to configure the jumpers for serial communication with host.

Jumper configuration:

Jumper	Configurations
J6	Open
J8	Jumper on pins 1-2
J9	Open
J29	Jumpers on pins 1-2, 3-4, 5-6, 7-8

Hardware connection for UART samples

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

  • Hardware configuration: No additional connection.

  • Build command:

    west build -p always -b ek_ra8m1 samples/drivers/uart/echo_bot/
    

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

  • Hardware configuration: No additional connection.

  • Build command:

    west build -p always -b ek_ra8m1 tests/drivers/uart/uart_basic_api/
    

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

    Board	Channel	Pin function	Pin	Connect to
    EK-RA8M1	SCI2	TXD2_C	PA03	Loopback to RXD2_C pin
    		RXD2_C	PA02	Loopback to RXD2_C pin

  • Build command:

    west build -p always -b ek_ra8m1 tests/drivers/uart/uart_async_api/
    

Hardware connection for SPI samples

• spi_bitbang (samples/drivers/spi_bitbang): Loopback for MISO and MOSI

• Note: The purpose of testing sample spi_bitbang on RA boards is to provide users with an understanding of the RA SPI driver. To test this sample using the SPI hardware IP, you can configure it by adding the overlay and configuration files with the following content:

  samples/drivers/spi_bitbang/boards/ek_ra8m1.conf

  CONFIG_STDOUT_CONSOLE=y
  CONFIG_SPI=y
  CONFIG_SPI_B_INTERRUPT=y
  CONFIG_SPI_B_RA_DTC=y
  CONFIG_LOG=y
  CONFIG_SPI_BITBANG=n
  

  • Note: We have to disable the CONFIG_SPI_BITBANG since we use SPI hardware IP to test spi_bitbang.

    samples/drivers/spi_bitbang/boards/ek_ra8m1.overlay

   spibb0: &spi1 {
     		rx-dtc;
     		tx-dtc;
     		pinctrl-0 = <&spi1_default>;
     		pinctrl-names = "default";
     		cs-gpios = <&ioport4 13 GPIO_ACTIVE_LOW>; // dummy config
     		status = "okay";
     	};
  
   &ioport4 {
     		status = "okay";
   };
