  • J-Link Debug Probe

  • 12V~20V power supply

  • Personal Computer

Board settings

Populate R966 and R967 to establish connection between FLEXIO1(as master) and LPI2C6(as slave).

  • HAL_PINCTRL_PLATFORM_IOMUXC_PAD_GPIO_IO09__FLEXIO1_FLEXIO_BIT9 , HAL_PINCTRL_PLATFORM_IOMUXC_PAD_GPIO_IO03__LPI2C6_SCL connected

  • HAL_PINCTRL_PLATFORM_IOMUXC_PAD_GPIO_IO08__FLEXIO1_FLEXIO_BIT8 , HAL_PINCTRL_PLATFORM_IOMUXC_PAD_GPIO_IO02__LPI2C6_SDA connected

Please note this application can’t support running with Linux BSP!

Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.

  2. Connect a micro USB cable between the host PC and the J31 USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board.

  5. Either re-power up your board or launch the debugger in your IDE to begin running the example.
