Default HW configuration

Use Debug On-Board mode: EK-RA4L1 board require to configure the jumpers for serial communication with host.

Jumper configuration:

Jumper Configurations
J6 Open
J6-A Open
J8 Jumper on pins 1-2

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_ra4l1 samples/drivers/uart/echo_bot/

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

    • Hardware configuration: No additional connection.

    RXD9 P511 Loopback to RXD9 pin

    • Build command:

      west build -p always -b ek_ra4l1 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_ra4l1.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_ra4l1.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";
 };
