We have a custom AM335x CPU board (arriving on my desk within the next few weeks) that has both NAND and NOR Flash. >> And how about SRAM chips or other memory mapped devices ? > > Not sure about SRAM (trying to think if I have a board with SRAM even), > but definitely, boards using the GPMC to interface to ethernet chips > need to be added. The board also contains an FRAM chip (which is just treated as SRAM). If you'd anything in the pipeline, I'm glad to help in any testing. I've created a custom cape board for the BeagleBone which contains the NOR flash and FRAM chips, so I'm not waiting for the new hardware to arrive. Cheers Mark J.
