TMS320F280049C: nc/hw_memmap.h Error/ Undefined Symbols Error/ General C2000 help

Part Number: TMS320F280049C
Other Parts Discussed in Thread: LAUNCHXL-F280049C, , C2000WARE

Tool/software:

Hello, I have been testing the TMS320F280049C on the LAUNCHXL-F280049C. I get led_ex1_blinky to work and some other examples as well. Sometimes however I come across the following error even though I have the correct includes. This is one of the most common errors I have received as well as the no symbol error.

"C:/ti/c2000/C2000Ware_5_03_00_00/device_support/f28004x/common/include/driverlib.h", line 45: fatal error #1965: cannot open source file "inc/hw_memmap.h"

Error Message:

Include Options:

Furthermore, I have created my own PCB with the TMS320F280049C on it. All the software that I have flashed on it I first test on the launchpad then modify it according to my PCB setup and flash it onto the board. I do this by editing the led_ex1_blinky.c file...(I erase the entire example file, paste my new code into the file, build, and compile). I have seen that it is not recommended to create your own projects and this is what I have been doing.

The issue arises when I try to use the #include "F28x_Project.h" header, originally this worked and compiled, however when I create a new workspace, import the same led_ex1_blinky.c file, erase the example code, paste my new code, I get an error that says "unidentified symbols". The code is the same, simply a new workspace. Therefore, I do not know if I included a path that allowed me to run the code originally in my first workspace but not in the second, I have tried everything to get the undefined symbols and inc/hw_memmap.h errors to go away.

Any advice on how I should go about creating a project, correct includes, how to get rid of these error, and general c2000 development on ccs would be appreciated.

Thanks.

    Hi, 

    The drverlib include path that you have specified should be till "driverlib" folder like "C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f28004x\driverlib"  . 

    Since you have added "inc" to this include path, it is looking for "inc/hw_memmap.h" file in this folder which does not exist. 

    As per the advice to get started with creating a project,  you can refer the empty project provided within C2000Ware located at <C2000Ware>driverlib\f28004x\examples\empty_projects\CCS. Later , you can add your files and update the include paths as required. 

    Best Regards
