Connecting to Target255
For a DB-25 connector, the cable connections are as listed in Table 8-2.
8.5.2Attaching to a Running Process Using
gdbserver
Using the
gdbserver
program, you can also connect to a running process on the target.
For example, the following command can be executed on the target to connect to a process with
process ID equal to 375.
gdbserver /dev/ttyS1 375
You can also use the TCP/IP connection by replacing the
/dev/ttyS1
with host-
name:port number as you have seen earlier.
