looking for a reference design for OMAP5910 (EMIFS read timings) - Backhaus Willy - Jul 7 7:26:00 2004

hello, we plan to use OMAP5910. looking at the EMIFS timing diagrams, I conclude that during an asynchronous read, it might happen that address lines and byte enable signals change before the OE goes high. in this case the processor would read an undesired memory (flash) location.. is this issue known? how can I avoid this? or where can I find a reference design for OMAP5910? ok.. we could buy the Innovator EVM, but before we buy that board, we would like to know if we can use this chip :) regards, Willy email: w dot backhaus at newage-avkseg dot com |
