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
