SPI with DMA mode for efusA9

  • Hello,

    I want to
    use SPI for efusA9 in DMA mode. What do I have to configure?

    Currently I’m
    testing SPI2: = SPI_A. Using DriverMethods 0 = IRQ and 1 = Polling it works.

    DriverMethod 2 = DMA the method DeviceIoControl with IOCTL_NSPI_SEND delivers
    FALSE and GetLastError() 1 (ERROR_INVALID_FUNCTION ???).

    My registry











    SPI driver"










  • Hello,

    sorry DMA mode is not implemented only POLL and IRQ.
