6. If using the gdbserver in muti process mode, enable MMUSPACES. Processes of Linux may

reside virtually on the same address. To distinguish those addresses, a debugger uses an

additional space-id, that specifies, to which virtual memory space an address refers. The

following command enables this additional space-id.

For more information on the space-id refer to the chapter Space-ID.

7. Establish the communication to the gdbserver:

A typical start sequence is shown below (connection via TCP)

Single process mode::

Multi process mode::

The start up can be automated by using the programming language PRACTICE.
