To debug any C\/C++ application on the device, first install gdbserver<\/strong> (after an Internet connection has been set up).<\/p>\n

To install gdbserver<\/strong>:<\/p>\n

    \n
  1. Using a terminal emulator, open a terminal to the device (SSH, debug console or similar).<\/li>\n
  2. At the command line, enter opkg update<\/strong>
    \n\u2022\u00a0After files are downloaded and extracted successfully, the system displays this message: Updated list of available packages in \/var\/lib\/opkg\/mlinux-mtcdt<\/strong><\/li>\n
  3. Then enter opkg install gdbserver<\/strong>
    \n\u2022\u00a0After files are installed successfully, the system displays these messages:
    \nConfiguring libthread-db1.<\/strong>
    \nConfiguring gdbserver.<\/strong><\/li>\n<\/ol>\n

    Once gdbserver<\/strong> is installed,\u00a0you must copy your application to the\u00a0Conduit\u00ae<\/sup> and then run it under gdbserver using\u00a0 the gdbserver-attach<\/b> command.\u00a0 To use gdbserver<\/strong> to run your program on the device:<\/p>\n

      \n
    1. Log on to the target system and run the gdbserver<\/strong> program. Enter this command:\u00a0\u00a0\u00a0 target> gdbserver comm program [args …]<\/strong>
      \na.\u00a0comm:<\/strong> how to communicate with GDB
      \nb.\u00a0program:<\/strong> the name of your program
      \nc.\u00a0args:<\/strong> its arguments<\/li>\n
    2. Attach your application to the gdbserver<\/strong> using arm-mlinux-linux-gnueabi-gdb<\/strong> on your development workstation (included with the\u00a0mLinux\u2122<\/sup> toolchain). To do this, enter the command:\u00a0 (gdb) target remote <target_ip>:<port>\u00a0\u00a0 <\/strong><\/li>\n
