Hi,

Im working on a prototype board for the AT91rm9200. I have been following the design of the AT91rm9200 EK.

In using the same flash as the obe used on the board, i have a small problem. Why have buffers been used between the chip`s lines and the lines of the flash?

i have seen boards that use different flash chips and dont have buffers for the flash. What is the use of the buffer then?

regards Mayank

You know I too have been digging into the EK schematics and i do not se any buffers between CPU and FLASH RAM. Am I missing something ? Please advise if you will, thanks, john
