Bay Trail E3800 Win7 I/O Drivers

I am in the process of writing drivers to access devices attached to the SPI on an E3800.

 

Does anyone have full working examples for any SPI  devices?

 

I have read through the following document and used the code from within it without success: Intel® AtomTM Processor E3800 Windows 7 IO Driver Software Developer’s Manual


Question:

  • Re; IOCTL_SPI_READ, IOCTL_SPI_WRITE
    • How do I specify the device register to be read/writing when sending a command
    • The SPI_TRANSFER_BUFFER has no place to specify the address we wish to read from.
    • From the example code in the document the read commands does not give an error but all the bytes rad are 0xFF..

 

Please help with example code or documentation detailing how to specify the address to read from in  interface.

I am moving this thread to Intel System Studio Forum since this question is specific to SPI driver interface.

Thanks and Regards
