Hi there, iMX51 + WEC700.

I need to drive a GPIO pin up and down just for debug and i guess the simplest way is to use cspddk lib.

I added the include files and lib and when i compile the application i have no errors.


When I run the application i receive a message: 'Impossible to import CSPDDK.dll' and in the debug log i see:

PID:00EA0122 TID:0C4F005A ERROR: c:\wince700\platform\common\src\soc\common_fsl_v3\cspddk\ddk_sdmav2\ddk_sdmav2.c line 1188:

PID:00EA0122 TID:0C4F005A SdmaAlloc failed!


Any idea?
