To connect to a target from GDB, you must configure RealView ICE to recognize your target devices. You do this by using rvigdbconfig to configure RealView ICE with the scan chain details. GDB is then connected to the core.
Power up your target hardware and RealView ICE unit.
Launch RVConfig, and configure the core by following the steps described in Opening the RVConfig dialog box — standalone method.
GDB is now connected to the core, and an image can be loaded and debugged.
For more information on the command syntax for rvigdbconfig, see Setting DCC parameters.
