Core Flex ERROR: No parameters found for flash id

With DC9.52 I have this error -and so many others-:
line 1 : WARNING ERROR: No parameters found for flash id received from pilot bios - using default parameters.
However if I compile and run with DC8.61 I get BOARD_TYPE = 0x2300 and the program runs.

What can I do to solve the error?

Thanks
