Debugger not working for ConnectME

We are using Digi ConnecME development board for our development. Currently we are facing some issues during debugging.
While executing the command gdbtk -se image.elf from the cygwin shell, debugger window is popping up but after the we are not able to continue the application. So we tried running source ./.gdbinit form the debugger console window, then the following error is coming

Error: ./gdbinit:9: Error in sourced command file:
No symbol “rdiromatzero” in current context.

Whether it is due to the debugger problem?

I have the same problem, can anyone help ?
