    Q:
    How do I configure the WinCE6.0 build for large CF card sizes (greater than 2GB) for the iMX31?

    A:
    The default registry settings in the
    lpd_imx31_pcmcia_imx31_50_x_x_x registry file are:

    "PccStrobeLength"=dword:00000005 ; Maximum value is 0x7F
    "PccStrobeSetupTime"=dword:00000005 ; Maximum value is 0x3F
    "PccStrobeHoldTime"=dword:00000009 ; Maximum value is 0x3F

    Running greater than 2GB CF cards:
    Our software support group has seen the following settings work on a
    larger (2GB )CF card in WinCE. In the file
    lpd_imx31_pcmcia_imx31_50_1_0_0,reg set the registry entries as follows:
    PccStrobeLength =dword:00000009 ; Maximum value is 0x7F
    PccStrobeSetupTime =dword:00000002 ; Maximum value is 0x3F
    PccStrobeHoldTime =dword:00000002 ; Maximum value is 0x3F

    For a tighter, improved response:
    The timings were successful (faster response for larger CF cards) with
    the following configuration settings:
    "PccStrobeLength"=dword:3 ; Maximum value is 0x7F
    "PccStrobeSetupTime"=dword:2; Maximum value is 0x3F
    "PccStrobeHoldTime"=dword:2; Maximum value is 0x3F
