AM2434: PRU Assembly Code Undefined Symbols Error?

Part Number: AM2434

Tool/software:

Hello Specialists,

I recently tried to use spinlock in a PRG0PRU1 core. I encountered undefined symbols error during compile phase.

The PRU core c-code (assembly code file declaration) is shown below:  

The assembly code (has compile error) is shown below:

Could anybody help to check what was missing?

Beside the error of undefined symbols, I also don't know how to use "#include" to get spinlock.h to be included (I tried to use direct c-disk file path, but was rejected with permission problem?)

Could you please also help to comment on how to remove the permission-limitations when I want to use file address in my c-disk for "#include" function? 

Thank you very much.         Jason, h
