-p Assign a range of ports to be used by Xilinx® GDB server, or disable the feature.

hw_server -p<port>

<port> is the base port number for Xilinx® GDB server. Default is 3000

The server opens one port per target architecture:

3000: Arm;

3001: Arm64;

3002: MicroBlaze;

3003: MicroBlaze64

hw_server -p0 disables the port

--init This option is used to specify an initialization script file to hw_server

hw_server --init my_init.txt

The file my_init.txt contains options that will be applied to the hw_server at startup

Environment variable HW_SERVER_INIT_FILE

Use to specify default --init file

export HW_SERVER_INIT_FILE=~/my_init.txt

  hw_server

In this case, the hw_server is initialized with the settings coming from the file pointed to by the environment variable HW_SERVER_INIT_FILE.
