EK‐RA8P1 Sample and Demo Hardware configuration

Followings are hardware connection and test samples for EK_RA8P1.

• Note: Following test/samples are running on CM85 core only. CM33 support and Multicore support are in-progress.

How to build samples with CM85 core:

west build -p always -b ek_ra8p1/r7ka8p1kflcac/cm85 <path to test/sample>

For example:

west build -p always -b ek_ra8p1/r7ka8p1kflcac/cm85 samples/drivers/uart/echo_bot

Use Debug On-Board

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

Set the configuration switches (SW4) on the EK-RA8P1 board as below:

SW4-1 PMOD1	SW4-2 PMOD1	SW4-3 Octo-SPI (OFF is Active)	SW4-4 Arduino / mikroBUS	SW4-5 I3C	SW4-6 MIPI	SW4-7 USBFS	SW4-8 USBHS
OFF	OFF	OFF	OFF	OFF	OFF	OFF	OFF

Hardware connection for UART samples

echo_bot (samples/drivers/uart/echo_bot): No additional connection.

zTest (tests/drivers/uart/uart_basic_api): No additional connection.

zTest (tests/drivers/uart/uart_async_api): Loopback for TXD and RXD

Loopback for TXD and RXD

Board	Channel	Pin function	Pin
EK-RA8P1	SCI2	TXD2	P801
		RXD2	P802

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_ra8p1_r7ka8p1kflcac_cm85.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_ra8p1_r7ka8p1kflcac_cm85.overlay

   spibb0: &spi1 {
  	rx-dtc;
  	tx-dtc;
  	pinctrl-0 = <&spi1_default>;
  	pinctrl-names = "default";
  	cs-gpios = <&ioport1 3 GPIO_ACTIVE_LOW>;
  	status = "okay";
  };
  
  &ioport1 {
  	status = "okay";
  };
