Xeon D 1559 LPC

[Athuljith]

How to Interface SPI flash of 256MB minimum, using LPC interface to Xeon D 1559? Is there a glue logic of FPGA/CPLD required to interface flash and LPC. Is there any LPC interface guide available?

Hi@CarlosAM_INTEL ,

Thanks for your response. I checked Section 13 of PDG document. As per the document The Maximum size of flash Processor can support is 64MB on each CS. But I have to use an 256MB flash to store my code. So I don't think I can directly interface flash with the processor. Can I use the LPC interface and a glue logic to achieve this? If so can you please provide some reference design. Or is there any other scheme to do this?
