This guide will explain how to setup an EDK 12.1 project to interface with two 16-bit Atmel (AT49BV322D, AT49BV322DT, AT49BV322A, AT49BV322AT) Flash Memory parts organized in parallel acting as a single 32-bit Flash Memory using the Xilinx XPS_MCH_EMC IP Core.
Tweaking of the XPS_MCH_EMC Properties is necessary because this Flash Configuration is addressed like a 16-bit Flash but data is read & written like a 32-bit Flash. By default, the XPS_MCH_EMC is not setup to handle this situation.
Though this guide has been written from experimentation with EDK 12.1, the procedures should be extremely similar to for earlier version of EDK.
- Create an EDK project and add an XPS_MCH_EMC Core.
- Open the Properties sheet, navigate to the User tab and ensure that the Common properties match those shown below.
