EVM430FR6989 calibration problem

Hi,

I am using an old version of EVM430FR6989 (Main Board Rev 7). Using the preload code to test the Gas/Water meter. This board always get stucked and display 8888. Is there any rules while this chip doing the calibration, like how to place the motor board.  How can I solve the stuck problem?

Thanks!
