LP-AM243: how to process this board_flash_open error?

Part Number: LP-AM243

Hi,

    when i run sdk demo on lp-am243, i met a problem, the message in Console and Terminal is that "[MAIN_Cortex_R5_0_0] ERROR: Board_flashOpen:199: FLASH open failed for instance 0 !!!"

    i think there is no communication between r5_0_0 and flash chip.

    how to handle this error?

    Hello，

    1. Check the hardware connection:
    Make sure all hardware connections between the LP-AM243 board and the flash memory chip are correct. Make sure the flash chip is properly connected and powered.

    2. Verify configuration Settings:
    View the configuration Settings in the SDK project. Check that flash configuration Settings (such as chip selection, size, etc.) match the actual hardware configuration. Make sure the SDK project is configured correctly for the LP-AM243 board.

    3. Check flash initialization code:
    Look at the code that initializes the flash. Make sure it configures the flash controller correctly and initializes the flash chip. Check the initialization code for errors or configuration errors.

    Thanks，

    Gary
