Hi,

Can you elaborate?

What it should do exactly?

What S32K part and compiler do you use?

The project is build and complied in IAR.

The requirement is to pass one Parameter form C file to assembly function. The c file has to call the assembly function with one variable. How the assembly cod can access this parameter?
