Hello All,
I had been working on Lyrtech DM648. Now I hv made my customized board by considering Original Schematics, The problem is, I am unable to write/read any data in its NOR flash. The only anomaly b/w schematics is the removal of MUX that swiches control between video ports and Flash, as I am not using the video ports so I hv removed the MUX and made a direct connection of flash with the DSP. According to the datasheet MUX has almost zero delay so I believe that there r no timing issues. I want ur suggestions to resolve the issue.Is the mux really necessary for proper communication with the Flash?
Thanks & Regards
Ahmed
