How to Add the Flash Driver for Eboot

The abstract of the document

The goal of this document is to guide the reader on how to modify the source code and re-build Eboot to support a new flash type on an EP93xx board. A basic familiarity with WinCE is assumed.



Note: 

(1) TE28F320C3, TE28F256P30, and AM29LV320D flash types are demonstrated. 

(2) A flash daughter card is used.

(3) Cirrus' WinCE 5.0 BSP release, Scorpius 1.0.202, is used.

(4) All of the examples have been tested on an EDB9312 evaluation board.

Create the environment

Assume that Cirrus' WinCE 5.0 BSP is used and $(WINCE500)\PLATFORM\ep93xx directory exists.

For 16bits FLASH, the user should select bsp of "CIRRUS EDB9315A: ARMV4I". For 32bits FLASH, the user should select bsp of "CIRRUS EDB9307/12/15: ARMV4I".

Add the flash driver
