hi!
which target are you debuging?
Generally,You can debug remote programm through stub , monitor
or gdbserver. This depends on your target board or cpu. Only gdb
support your target,you can use remote stub .and if the rom monitor is provided by the vendor,you can use it. Both through the two ways above,you can load the target rom/ram/flash data to gdb.
thank you!
