CCS/TMS320F28069M: LAB1 Datalog problem TMS320F28069

TMS320F28069F: Compile issue adding datalog.c to proj_lab11a

Other Parts Discussed in Thread: MOTORWARE

I've been trying to add datalog.c from v18 proj_lab1b to an application based on V16 proj_lab11a but keep running into compile issues. see error below.

I copied the datalog module into the TI v16 sw/module/ directory.  Then added the module in CCS using the add file project menu.  However, after adding the code snippets the compiler doesn't seem to pick up on the addition of a new module.  What step am I missing.  I didn't see an explicit declaration of datalog.c or .h in the proj_lab1b example.

However, to see if this was the issue I added an explicit include for  datalog.h in main.h and then I get this error.

    So after doing more research I decided to leave in the explicit include of datalog.h in main.h and work on the link warning. 

    The solution to the warning is adding this to F28069F_ram_lnk.cmd

       graph_data       : > RAML0_L8,   PAGE = 0

    Which I found from in the v18 project.  With that added the project compiles successfully.

    I get that the memory section needed to be defined, but why did I have to explicitly include datalog.h in main.h in my v18 project where as it wasn't in the v16 project?

    That means the reserve RAM is not enough for datalog data buffer. You should change the .cmd file refer to the lab01b, and add datalog.c to the project, and the search directory in project properties for datalog.h.
