I am using the Hyper PXA255B developing board,The board have three UART:
SUART, BTUART and FFUART.

The SUART is used as a debug serial, and it works properly. I can load the
BTUART driver successfully, and it works as COM1.

Now my problem is I can't load the FFUART driver successfully! I have read
the driver source code, and I can make sure the BTUART and FFUART use the
same driver xsc1bd_serial.Dll. The IoBase of the BTUART is 0xa6400000, and
the IoBase of the FFUART is 0xa6300000.

The registry setting of the BTUART are as follows:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial]
"Dll"="xsc1bd_serial.Dll"
"IoBase"=dword:a6400000 ;BTUART_BASE_U_VIRTUAL
"IoLen"=dword:24
"Irq"=dword:0 ;21 - Dummy value. This subkey is not
really used by the driver.
"Tsp"="Unimodem.dll"
"DeviceArrayIndex"=dword:2
"Prefix"="COM"
"Order"=dword:0
;"Index"=dword:4
;"Priority256"=dword:67 ; Using default priority value
"DeviceType"=dword:0
"FriendlyName"=LOC_DISPLAYNAME_SERIAL
; Eliminate flow control bit
"DevConfig"=hex:
10,00,00,00,05,00,00,00,10,01,00,00,00,4B,00,00,00,00,08,00,00,00,00,00,00

according to the above settings, I set the FFUART registry as:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial1]
"Dll"="xsc1bd_serial.Dll"
"IoBase"=dword:a6300000 ;FFUART_BASE_U_VIRTUAL
"IoLen"=dword:24
"Irq"=dword:0 ;21 - Dummy value. This subkey is
not really used by the driver.
"Tsp"="Unimodem.dll"
"DeviceArrayIndex"=dword:3
"Prefix"="COM"
"Order"=dword:0
;"Index"=dword:4
;"Priority256"=dword:68 ; Using default priority value
"DeviceType"=dword:0
"FriendlyName"=LOC_DISPLAYNAME_SERIAL
; Eliminate flow control bit
"DevConfig"=hex:
10,00,00,00,05,00,00,00,10,01,00,00,00,4B,00,00,00,00,08,00,00,00,00,00,00

but, the FFUART driver can't load successfully.

Please help me!

Thanks
