Unable to find dynamic linker breakpoint function

Lee Holeva
Genius 4615 points

I am attempting to run gdb, which came with the SDK,  remotely to see what a program running on the C6a816x EVM ARM is doing and I get this:

(gdb) target remote 192.168.1.10:4567
Remote debugging using 192.168.1.10:4567
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
0x00000000 in ?? ()
(gdb) b main
Breakpoint 4 at 0x9d08: file track.c, line 7.
(gdb) cont
Continuing.

Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()

A couple of questions:  is the warning about Unable to find dynamic linker breakpoint function normal?  I compiled the code using the -g option.  Second, whenever I run from a breakpoint I get a segmentation fault and can do nothing further.  As far as I can tell the fault is coming from gdb, not the program itself as the program runs fine on its own.

    Hello,Lee Holeva

    I also meet this problem. Can you tell me your GDB's version?

    Make sure that you're using the correct gdb, the one that came with your SDK:

    arm-none-linux-gnueabi-gdb runDSP

    I had a very similar problem and from googling around I changed the gbdinit file found in /etc/gdb and added the line:

     

    set solib-absolute-prefix /path/to/nfs/folder

     

    then in code composer i told it where to find the gdb command file.

    Hope this helps!
