linker complaining about dual boot.obj definitions

Robert Wolfe

Hello,

I'd like to bring C:\ti\ccsv6\tools\compiler\c6000_7.4.14\lib\src\boot.c into my local project, in order to turn on debug symbols and debug a problem I'm having with putting .cinit into external memory, per this thread:

https://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/115/t/542435#pi317286=4

However the resulting local boot.obj is conflicting with the library version of boot.obj, per this linker error message:

<Linking>

error #10056: symbol "__stack" redefined: first defined in
"./drivers/boot.obj"; redefined in
"C:/ti/bios_5_42_01_09/packages/ti/bios/lib/bios.a674<boot.o674>"
error #10056: symbol "_c_int00" redefined: first defined in
"./drivers/boot.obj"; redefined in
"C:/ti/bios_5_42_01_09/packages/ti/bios/lib/bios.a674<boot.o67

There must be a way to tell the linker to use the local boot.obj, and ignore the library version, but I've not had any luck finding that method.

Please advise,

Robert

    You brought this file into your project ...

    That older thread does something different.  The user is named Brad.  He brings in these two files ...

    C:\ti\bios_5_42_01_09\packages\ti\bios\src\aux62\boot.c

    C:\ti\bios_5_42_01_09\packages\ti\bios\src\aux62\autoinit.c

    You bring in boot.c from the compiler RTS library.  Brad brings in files from the BIOS implementation.  Not the same thing.  These files serve similar purposes, i.e. system start-up.  But they are not identical.  You need to bring in the BIOS implementation of these files, in a manner similar to Brad.  I don't know BIOS well enough to advise you on the details.  

    Thanks and regards,

    -George

    George,

    That did it. Thanks much. I haven't started the debugging yet, but it appears I am able to step through c_int00, etc now, after using those files instead.
