Dear all, I'm learning embedded linux development and need help on my task.
I'm trying to communicate with a FPGA via the GPMC bus on my Overo FE board and need assistance with writing a simple device driver & test application that uses the GPMC bus to read & write a WORD size data and also a BLOCK of WORD data to the FPGA. The FPGA-OMAP3530 will be use synchronous read/write over the 16-bit datapath and CS 6. The GPMC bus is shared with an Ethernet chip and NAND chip as per Gumstix COM + TOBI/Chestnut design and these standard devices must still work as per norm. I've been searching via GMANE for similar questions but some are pointing to non-existence archives. I believe I have to develop a kernel device driver to register the FPGA and from which will expose a device node for the test application. or is there a generic GPMC driver that does it? Can someone share with me similar layout and code so that I can base my learning from a starting point? Many thanks in adv. -- Regards, James -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
