Run Placement Fails for section ..." error in ezdsp f2812

Matheus Martins

I'm programming the DSP F2812 and during the compilation of my code the following error appeared:

Can anyone tell what to do to resolve the error?
I've tried in all versions of code composer and all have the same error.
PS: The same code has been tested before on another computer and another CCS and it worked.

If necessary put the code here.

Matheus,

If the same code has been tested and worked on another computer, I would check that you are linking in all the files needed (such as the linker command files) into your CCS project since paths can change in different working environments.

Additionally, there are several threads regarding "program will not fit into available memory" on the C2000 forum that are worth searching and looking at, if you haven't already.

Useful wiki on understanding linking: http://processors.wiki.ti.com/index.php/C28x_Compiler_-_Understanding_Linking

The "10099-D" warning explained: processors.wiki.ti.com/.../10099

If you are still having no success, attach a text file with the debugger output detailing the errors/warnings as well as the linker command file being used so I can provide further assistance.

Best Regards,

Chris

I edited the memoirs map and managed to compile, but the DSP output that took a square wave compiling on another computer, that with the memory map edited only noise comes out. There is the possibility of editing the map memories have compiled, but unusable its implementation in DSP?

Matheus,

That's great that you got it to compile! You're saying that the output is different from the same project on one computer vs another? You only made memory map changes? Did you alter the code at all? If the same files and environment are replicated on another computer, the outputs should be the same.

Best Regards,

I know that the problem is in the memory map, and I know I optimize code or allocate the instructions in another section of the map, but I can not do that yet (I'm beginner), so ... It would be troublesome if I asked to give a look at the code and tell me what to do or who knows resubmit corrected?

Matheus,

Adjusting the memory map could lead to (what you mentioned earlier) unexpected output because its the register structures that are failing to be placed in memory. This could be from using a different compiler version. I'd check to see what was being used in the scenario that you mentioned that everything worked.
Here are some examples for F2812 that might help to look at: http://www.ti.com/tool/sprc097

I've tried to do this, but the work environment in question uses the 3.1 version of Code Composer, but is only available for download today versions greater than version 4. I do not know what to do because I can not edit the map memories or reproduce the work environment on another computer ...

Matheus,

I've had success building the CCSv4 examples in CCSv6 from http://www.ti.com/tool/sprc097 which use the same nonBIOS header linker command file that your project uses and is having errors. The unfortunate easiest solution at this point when dealing with a CCSv3 project that is causing questionable issues is to re-setup your project in a new, clean CCSv6 project and not use your original CCSv3 project. You can port in your main source and other project specific files as well as make use of the source/headers provided from that package I linked to above.

Here are some workshops that can assist in learning about CCS and the device: processors.wiki.ti.com/.../C2000_Archived_Workshops
