TMS320F28388D: Migrating from 379D library to 388D library causes “warning #10068-D: no matching section”

Ed, 

Pls share the console log .  Will forward your query to the Flash expert.

Hi Siddharth,

I have attached the file.  I have removed IP from it.

Thank you,

Hi Ed,

Along with the library, did you replace all the required headers as well?

Thanks and reards,
Vamsi

Hi Vamsi,

Yes.  But keep in mind that for the sake of isolating this issue, the calls to the library are currently commented out.

Thank you,

Ed

Hi Ed,

Did you try to import/compile the F2838x flash API usage example from the C2000Ware?  Did that work fine for you?

Thanks and regards,

Vamsi

Hi Vamsi,

No.  I simply replaced all of the old files with the new files.

Thank you,

Ed

Hi Ed,

Can you try the example first and see how it goes?

I may need a dummy project to reproduce on my side.  Is that line 36 warning referring to the  " --library=F2838x_C28x_FlashAPI.lib<FlashStateMachine.obj> (.text:Fapi_setActiveFlashBank) "?

Thanks and regards,
Vamsi

Hi Vamsi,

Yes.  Line 36 is the line you mentioned.

Where can I find the example project?

Thank you,

Ed

Ed,

Generally the flash API examples are available in C2000Ware:

Examples:

C2000Ware_5_01_00_00\driverlib\f2838x\examples\c28x\flash\

C2000Ware_5_01_00_00\driverlib\f28p65x\examples\c28x_dual\flash.

Let me know how it goes.

Edited for others that may refer to this post.

Thanks and regards,
Vamsi

Hi Vamsi,

We are currently using C2000Ware_4_00_00_00. Maybe that is the issue?  At any rate, I have downloaded 5_01_00_00 and am trying to use it.  I tried to load the flashapi_ex1_programming project but received a dialog box stating that Compiler version ’22.6.0.LTS’ is not currently installed.  Where can I find that?

Also, I don’t think it makes any difference, but we are using CCS 10.4.0.00006.

Thank you,

Ed

Hi Ed,

I don't think using the previous C2000ware can cause an issue.  

To get that compiler version, you can either upgrade the CCS to the latest CCS12.x version Or install the codegen tools from here:  https://www.ti.com/tool/C2000-CGT#downloads 

Thanks and regards,

Vamsi

Hi Vamsi,

I am now running  CCS Version: 12.5.0.00007 with compiler version TI v22.6.1.LTS, and using the Flash API files from C2000Ware_5_01_00_00, and getting the same result.  What else can I try?

Thank you,

Ed

Hi Ed,

You mean to say that the C2000Ware example as-is also giving you that warning?

Thanks and regards,

Vamsi 

My apologies Vamsi,

I guess I was hoping that getting the latest would resolve our issue, and that result is what I reported.

For the example project, using the latest tools, I tried loading the project at the path which you posted, and got the following:  I also tried using the f2838x folder, and received a similar result.

Ed

Hi Ed,

I asked our team to import the project and see if they also are able to reproduce this issue.

We will get back to you in a day or two.

Thanks and regards,
Vamsi

Hi Ed,

Quick question:  You mentioned you are migrating to F28388D.  Why are you trying to import F28P65x example?  The image that you shared shows F28P65x example and hence is the question from our team.  

Thanks and regards,
Vamsi

I used the path which you gave me.  I had the same question.  That is why I also tried the 388 path.

I can't help but feel that I don't know how to properly set up the example projects, and that is why I am getting the results I am getting.  Is there a guide which shows how to do that?

Thank you,

Ed

Hi Ed,

Understood.

Coming to the original warning (warning #10068-D: no matching section) that you asked about:  I tried couple of experiments and found that this warning gets issued when we included a library or a specific function from the library in the linker command file,  but did not actually use that function yet in the application.

Is that the case with you?  Or do you get that warning even if you use that flash API function in your application?

Please let me know.

Regarding the example usage help:  I will ask our team to see if we have any guide.  If needed, I can ask our team to have a quick meeting with you to help you on that.

Thanks and regards,
Vamsi

Hi Vamsi,

The call to the function is currently commented out.  If it is uncommented, then the linker produces a link error with Fapi_setActiveFlashBank(Fapi_FlashBankType) as an undefined symbol.  Maybe that is a clue?

I would be happy to meet with your team to figure out how to build the example projects.

Thank you,

Ed

Ed,

Ok, then the warning is because of not using the function as I mentioned.

What is the exact error that you got regarding the undefined symbol?  Maybe you did not include the required header file - please check the example and include the required headers.

Regarding the meeting: Sure, will arrange one if there is no such guide.  Will let you know.

Thanks and regards,

Vamsi

Hi Vamsi,

The warning exists either way.  With the source code line uncommented I get both the link warning and the link error as shown below.  With the source code line commented out, I only get the warning.  If I then comment out the entry in the linker command file, the warning goes away.

 <Linking>
"<path to cmd file>/<FileName>.cmd", line 36: warning #10068-D: no matching section
 
 undefined                                   first referenced                             
  symbol                                         in file                                  
 ---------                                   ----------------

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "<project name>.out" not built

Thank you,

Ed

Ed,

Ok, I will ask our team to have a meeting session with you to help clear these issues.

They will approach you via the friendship request.

I will keep this thread in pause for now.

Thanks and regards,
Vamsi
