Part Number: AM5746

Tool/software: TI-RTOS

Hello, TI Experts,

 

Our customer sent us additional questions from the below E2E-thread.

 

They use GCC GNU v6.3.1(Linaro).

And they try to use the option "--mapfile_contents=sym_defs" like below.

 

But we found error like below on CCS.

"arm-none-eabi-gcc.exe: error: unrecognized command line option '--mapfile_contents=sym_defs'"

 

Question:

Could you tell us how to generate static variables information to map-file for GNU?

 

Best regards,

    I apologize for making an error on the earlier related forum thread.  I failed to notice that you use the GCC ARM compiler, and not the TI ARM compiler.  This option ...

    --mapfile_contents=sym_defs

    ... only works with the TI linker.

    I could not find a way to display static variables in the map file.  You can however, use the command line utilities arm-none-eabi-nm (the names utility) or arm-none-eabi-objdump (the objdump utility).  For both utilities, use the option --help to see a usage summary.  With the names utility, static variables are displayed by default.  With objdump, use the option --syms.

    Thanks and regards,

    -George
