Header file (rom.h) not working appropriately

udit daga

I'm using CCS v5.2.1 for Stellaris Launchpad(LM4F120H5QR). I've included the header file rom.h present in driverlib directory but still the ROM functions are not working. The compiler is showing an error that Unresolved symbol (say ROM_IntEnable) first reference in main.obj. I'm attaching the code and the screenshot of the errors please help. Urgent.

Hello Udit Daga,

Open Rom.h file and you will find that the functions you called are not defined because the conditions of #if statements are not satisfied.

Right click your project, and choose property (alt + Enter), switch to predefined symbol tag:

You can check your predefined symbol on that and whether it matches Rom.h or not.

Regards,

Jo

Dear Udit Daga,

Try add the following strings into pre-define NAME window:

PART_LM4F120H5QR

TARGET_IS_BLIZZARD_RA1

Regards,

Jo

This case is project correctly tageted to proper processor? See in property what is assigned as processor, and library path too.
