Cortex A15 ARMDS 22.2 Breakpoints not working in C code, only in assembly?

Raghu Halharvi

Hello,

Any help here will be appreciated, My target is A15 running threadx code, breakpoints work fine in *.s or Assembly file but don't respond or stuck in *.c file

I am new to ARMDS interface, I did look at this discussion but didnt know where to pass the extra flag/option EL1N:0 in ARMDS 22.2

    Hello Stephen,

    Thanks for the response

    I have made sure the optimization level is minimum -O0 with -g and also verified there is no optimisation done by the compiler.

    The firmware is directly loaded into RAM by the loader, the offset is 0, attached the screenshot, added the N:0 as argument in debug connection tab.

    Hi again

    The "N:0" is an argument for an "add-symbol-file" command, not an argument for the program.

    An "add-symbol-file" command is used to load debug information from a debug .axf into the debugger.
    See developer.arm.com/.../add-symbol-file

    To execute an "add-symbol-file" command, open the "Commands" view.  At the bottom of the "Commands" view is a "Command" field.  
    In the "Command" field, enter:
    add-symbol-file \path\to\your.axf

    If your program switches between security states, you may need both
    add-symbol-file \path\to\your.axf N:0
    and
    add-symbol-file \path\to\your.axf S:0

    These commands can also be added into the Debugger tab of the Debug Configuration, or into a .ds script file, to help automate the process.

    Hope this helps

    Stephen
