Hi,

please make sure you refresh the index, right click your project and select index then "refresh All" then "rebuild Index". Also check the following page of free examples using the interrupt handler:

thanks for your reply,

after a while i managed to solve this issue, by going to system.h in BSP file, I looked for "ADVANCED" and changed it with "ENHANCED", then I built the program from application (hello word.c) not from System builder, and it worked fine.

Thanks
