AM1808 - Using EMIFA to connect to NAND as well as an FPGA

Matt C said:

Our customer wants to connect both NAND flash memory and an FPGA (asynchronous-SRAM like interface) to the EMIFA on AM1808.  Is this possible?

Yes, this is possible.

Any suggestions or recommendations on how to go about doing so?

There are 4 chip selects on the EMIFA that are appropriate for NAND and a FPGA interface.  These are /EMA_CS[5:2].  If the customer desires to boot from NAND, the AM1808 on-chip bootloader requires the NAND device to be connected to /EMA_CS[3], per the application note Using the AM18xx Bootloader (Rev. A) in Chapter 6.

The FPGA could then be connected to /EMA_CS[5:4].
