 On Linux systems, you will need to edit the system-settings.cmm file to manually add the serial port to connect to the Portenta H7 board. This is a text file and can be opened with your favorite text editor. Edit the line that defines &GDBPORT to refer to the serial port, for example: `&GDBPORT="/dev/ttyACM0"`. This must be done **before** you start the TRACE32 software. After changing the port you can start the TRACE32 debugger or re-start it in case it was open while you made the changes.
