Please share any document regarding code generation and flashing of MPC5777C, with lauterbach debugging tools and S32Design studio
first you have to install Lauterbach plug-in:
Then please create a new project using project wizard - select Lauterbach TRACE32 Debugger.
The new project should work as-is. No need to adjust any script.
Debug runs in standalone TRACE32 IDE and not in eclipse.
Hope it helps.
