i use S32DS（Version: 1.1 ） to develop program on MPC5775K, and find it seems  there is  a compile bug of the code.

The source code and its assemble code lists below. (The program has attached!)

 

 

The compile use r31 and r0 for localDW->ISV_RadarEnSwitch_prev and localDW->ISV_RadarEnSwitch_start.

But from previous program r11 store the value of localDW->ISV_RadarEnSwitch_start and  r12 store the value 

localDW->ISV_RadarEnSwitch_prev.  

 

 

Can anyone help me for that?  Thank you very much!

Please update to S32DS for Power 1.2. Along with a lot of IDE fixes it also has a lot of fixes in compiler codegen. Here is a snip from your project with new compiler:
