Title: Support for SD card addition by wince

Abstract:

Note: Windows CE 5.0

Date: 2010.5.5

Name: Zhu minglei

========================================================== ==================================

The drivers and components to be added are as follows:

① Device Drivers | SDIO | SD Memory

② Device Drivers | SDIO Host | Samsung 2410 SDIO Host

③ Core OS | Windows CE devices | File Systems and Data Store | Storage Manager | FAT File System

Add a FAT file system to read and write the SD card.

The Registry content related to the SD card is as follows:

; Setting for SD bus driver to load driver

[HKEY_LOCAL_MACHINE/Drivers/SDCARD/HostControllers/SDSC]

"Dll" = "SDCSDCard. dll"

Modify the name of the SD card drive to SDCard:

[HKEY_LOCAL_MACHINE/System/StorageManager/Profiles/SDMemory]

"Folder" = "SDCard"; notears

Copy Files first, then Sysgen system, re-burn NK, start the system, plug in the SD card to test it,
