the contents in Data flash be changed to 0xFF after download a new hex by PE

hi NXP experts:

I meet the problem as show in the title: 

I did a data flash driver by myself rather than taking use of EB fee driver and it seems works OK because I can see the contents in the memory windows in the S32DS and after power shutdown and power on again, the contents is still in the data flash(by typing the address of data flash)

but after a add some code in the project and compile download again I find the contents in the data flash is changed into 0xFF。 it makes me feel confused.

could you pls help me ,thanks a lot.
