Interface compact flash to Processor memory interface

[rakeshm55]

How to interface compact flash to memory interface of a processor?? eg GPMC interface
Is the interface similar to NAND??...

How hard is it to bring up the interface

Please share some example designs for the same... If OS like linux in involved is it advisable to choose such an interface for Kernel as long as there is no support??

CF-ATA, electrically it's the same, but it's a subset of the protocol.



I know because we (at DTB) are using a router for a project with a CF interface, and ... we had to modify the ata-kernel-module with patches specific for the CF-ATA.
