I do debugging, so I have a breakpoint, but compiler jumping the breakpoint.

cache off for single step...

Thank you for answered, but I don't understand.

I found that single stepping with the Cache turned on made the IDE unstable.

Which processor are you using ?

Or no machine code associated with said source lines ?

Be more specific.

I using STM32F429. And My code part is :

  uint16_t tempfloat;

tempfloat = (paramatres[5] & 0x00FF) << 16;

tempfloat |= (paramatres[6] & 0x00FF)<<8;

tempfloat |= (paramatres[7] & 0x00FF);

What about the project settings ?

With optimization levels greater or equal to 1, the compiler reorganizes the code, and single-stepping can be full of surprises.
