Hi,

I have a project that flashes F280049C LaunchPad LEDs in CLA.

I got some error messages as below when compiling this project in RamDebug configuration:

the CLA functions are saved in F28004xCLA.h as inline functions.

fGblUDelay3 and fGblUDelay4 are defined at the beginning of F28004xCLA.cla, and also defined in

F28004xCLA.h as external variables.

Could you please let me know the reason of these compiling error messages and how can I avoid them?

The project is attached as below:

1-ph Pwm with DC input (C code).zip

Thanks,

Jiakai

Hi,

I am able to reproduce the issue with the CCS project you shared. I tried adding similar globals and inline functions in one of my other CLA based projects, which seems to build fine. So from the compiler side, there doesn't seem to be any issue in having extern variables defined in .cla file. Could you double check your header files once and make sure there are no issues

Hi Veena,

The CLA project is automatically generated, each line of code in both .h file and .cla files is ended with "\r\n",

I don't know if that causes the compiling error.

By the way, if I move all inline function bodies into Cla1Taskn and all error messages disappeared.

thanks,

Jiakai

Hi Veena,

Thank you very much!

By the way, I have changed my code so the CLA code can be put in one .cla file, it can pass ccs compiler.

I think it is an encoding issue. I opened the file in an editor and changed it to Windows(CR LF) and it worked.
