DS-5, how can i make launching the debugger from the command-line console

Hallo, every one:

I have a big Problem to ask here and i need your help:

We use the Altera Cyclone V SOC(Cortex A9) Chip in our project.

Wenn we work under DS-5. with Debug directly in DS-5 there is no Problem, but i want with DS-5 Command Prompt using "debugger" command to debug our Chip, so i have found some info:

-> debugger --target --script ...

so what should i do with the target Option? i have tryed with our gdbserver(127.0.0.1:3010), but it do not worked, then i must use a RVC file or what(how can i get the RVC file)? Could someone help me?

Thanks a lot, Guys!

MfG!
