EK‐RA6M1 Sample and demo Hardware configuration

Followings are hardware connection and test samples for EK-RA6M1, for more detail on 1st setup hardware connection, please visit EK-RA6M1 - Quick Start Guide and EK-RA6M1 v1 - User's Manual

Default HW configuration:

Zephyr UART Console setting: EK-RA6M1 board require to connect with a USB UART board to communicate with PC console

e.g. PMOD USB UART

Pin configuration:

Board	Channel	Board Pin function	Board Pin	Connect to PMOD B
EK-RA6M1	SCI8	TXD8	P105 (PMOD B)	USB UART RXD pin
		RXD8	P104 (PMOD B)	USB UART TXD pin
		GND	GND	USB UART GND pin
		P3.3V	VCC	USB UART VCC pin

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_ra6m1 samples/drivers/uart/echo_bot/

    west build -p always -b ek_ra6m1 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_ra6m1.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_ra6m1.overlay

   spibb0: &spi0 {
     		rx-dtc;
     		tx-dtc;
     		pinctrl-0 = <&spi0_default>;
     		pinctrl-names = "default";
     		cs-gpios = <&ioport4 13 GPIO_ACTIVE_LOW>; // dummy config
     		status = "okay";
     	};
  
   &ioport4 {
     		status = "okay";
   };
