Debugging a compiled file compiled on Eclipse

Alan.Blumenstein

Hi everyone,

I'm trying to debug a file compiled in Eclipse with the uVision version V5.14.0.0 in a microcontroller STR912FAW47. I can insert breakpoints in the assembler windows but the option is disable when I try to do the same in the windows with the C code (figure). Do I need to add something on the makefile to activate the debbuging?

Thanks in advance

Regards

Alan Blumenstein

    Hi Alan

    I've not seen that error before, but it might indicate that the debug information is being generated incorrectly, which might then explain why the debugger is unable to handle it.

    A quick Google search for "Location lists in .debug_info section aren't in ascending order" points to this being caused by a bug in the toolchain.  To avoid this, you could try changing your source code, or reducing the optimization level.

    As a quick check, try compiling a simple Hello World program with "-g", then use readelf.  You should see something like:

    :
    Contents of the .debug_info section:

      Compilation Unit @ offset 0x0:
       Length:        0x22 (32-bit)
       Version:       2
       Abbrev Offset: 0x0
       Pointer Size:  4
     <0><b>: Abbrev Number: 1 (DW_TAG_compile_unit)
        <c>   DW_AT_stmt_list   : 0x0
        <10>   DW_AT_low_pc      : 0x80010128
        <14>   DW_AT_high_pc     : 0x80010278
    :

    Then load the image into the debugger.  Are you able to debug Hello World at source level?

    Hi Stephen


    I made the minimal possible configuration for the system (keeping the ECOS configuration without change) and compiled the system, now when I run the arm-elf-readelf, there is no error back and it generates a file with a similar message as you described in your previous message. Anyway, I cannot debug it at source level.

    Any other suggestions?

    Regards
