PRU development with CCS getting errors

Bob D.
Expert 2430 points

I'm trying to build a sample program using CCS 6 and the Biss C application in Tidc920. I created an assembly project for the PRU  and loaded the .p and include files into the project. When I go to build in CCS, I get

warning #10211-D: cannot resolve archive C:/TI/ccsv6/tools/compiler/ti-cgt-pru_2.1.1/lib/libc.a to a compatible library, as no input files have been encountered
fatal error #10009: no input files

>> Compilation failure
gmake: *** [PRU Test.out] Error 1
gmake: Target `all' not remade because of errors.

**** Build Finished ****


The file builds fine if I use pasm.exe from DOS.

What's wrong with my setup?

Thanks.

    Is the project going to contain only assembly source files or a mix of assembly and C? If only assembly, then be sure to select "Empty Assembly-only Project" when creating the new project, else select "Empty Project". 

    If your assembly source file has .p extension, change it to .asm as CCS does not recognize .p by default.

    Let us know if this helps.

    Hi Aarti, Yes for now the project has only assembly, and I did create it as an assembly only PRU project. It's the file from the referenced Ti app note. When I use .p I get the errors shown. If I change the name to .asm it totally blows up with errors on EVERY single line.

    Bob,

    Can you copy the build log (full output in the build console) to a text file and attach it here?

    Hi Aarti,

     The first file is using .p as the file name, the second is using .asm. I had to condense this one since there were so many errors it overflowed the build console buffer and cut off the 1st portion. I stopped the build so I could capture the first few lines.

    Thanks,

    Bob

    Bob,

    The source file you are using appears to be designed to work with the older PRU assembler tool, called PASM. Please see these wiki pages for more information.

    http://processors.wiki.ti.com/index.php/Programmable_Realtime_Unit_Software_Development

    http://processors.wiki.ti.com/index.php/PASM_Tool

    This older development model is now replaced by the PRU Compiler/Assembler in CCS. However, the source code format for pasm is not compatible with the CCS Compiler, which is the reason for the error messages you are getting in CCS.

    In the near term to get things going, you can build the .p file on command line using pasm (outside of CCS). Note though that since this is an older tool and not actively supported anymore, the long term solution would be to migrate the source code to work with the TI assembler. The references to TI Compiler and Assembler for PRU can be found as links in this page:

    Hi Aarti,
    Thank you. I thought since the app note came out in February 2015 (and is still marked "preliminary") it would have worked with the latest tools.
    Thanks.
