From instructions, I opened two console:
Console 1: openocd -f board/stm32mp15x_dk2.cfg
This looks good as output:
```
...

```
Console 2:
gdbgui -g "arm-ostl-linux-gnueabi-gdb -x gdb-script/Setup.gdb"
gdb-script folder is in same location where I run run command.
If I don't pass '-p 3333' then default is 127.0.0.1:5000 and failed.
If I add -p 3333 then:
OSError: [Errno 98] Address already in use
I already reset computer to "kill the gdbgui instance running in background" but did not help!
Anyone know how fix this issue?
And, the port is 5000 or 3333 if I want to debug over ST link?
edit:
Look to me port 3333 is right one. When look at console 1 where openocd start, I see:
```
Info : New GDB Connection: 1, Target stm32mp15x.cpu0, state: halted
Warn : ignoring character 0x47
Warn : ignoring character 0x45
.....
Warn : keep_alive() was not invoked in the 1000 ms timelimit. GDB alive packet not sent! (1016 ms). Workaround: increase "set remotetimeout" in GDB
```
When use port 5000 nothing happen at all.
Still see "OSError: [Errno 98] Address already in use" from gdbgui console if use port 3333
