Hello I using CORTEXR4RM48CCS5 demo file on CCSV5.2, but it does not build success. And, I only change code that the “mainCREATESIMPLEBLINKYDEMOONLY” set to 1. The error like graphic, what can I do to solve this problem? Or, is there an operational process that can be used in this demo?

__clz is an intrinsic provided by the compiler. I guess the name used by the compiler has changed. Check the compiler documentation – it might be something like __CLZ – or any other variation.

Hello I do not find the compiler documentation in CORTEXR4RM48_CCS5. Can you tell me the path or where the compiler documentation?

The compiler documentation will come with the compiler, so wherever you have installed the compiler.
