3.添加文件到 PLATFORM.BIB 中.
; SD BUS driver
SDBusDriver.dll $(_FLATRELEASEDIR)\SDBusDriver.dll NK SH
; SD host
SDCSDCard.DLL $(_FLATRELEASEDIR)\SDCSDCard.DLL NK SH
SDMemory.dll $(_FLATRELEASEDIR)\SDMemory.dll NK SH
SDBusDriver.dll $(_FLATRELEASEDIR)\SDBusDriver.dll NK SH
; SD host
SDCSDCard.DLL $(_FLATRELEASEDIR)\SDCSDCard.DLL NK SH
SDMemory.dll $(_FLATRELEASEDIR)\SDMemory.dll NK SH
4.添加注册表项目:
; charlie, SDIO

; own ActivateDevice call in the Entry point provided

5.系统启动后,SDBus.dll和SDHC_SC2410.dll能在注册表HKEY_LOCAL_MACHINE\Drivers\Active 看到.
6.调试.
一般先从底层开始,是否发生系统硬件中断,打印中断信息.
返回系统中断信息 :SYS_SDXXX
说明系统硬件是正常的 ,再开始调试其他部分.
