This test framework does not # address the issue, so it's best to set this variable # in your baseboard configuration file. # FIXME: there's no reason why the test harness couldn't # pass commandline args when it spawns gdbserver. # # set_board_info gdb,noinferiorio 1 # Neither the traditional gdbserver nor the one in libremote # can presently capture stdout and relay it to GDB via the # 'O' packet. This means that tests involving printf will # fail unles you set this varibale in your baseboard # configuration file. # # set_board_info gdb,no_hardware_watchpoints 1 # Unles you have a gdbserver that supports hardware watchpoints. # FIXME: gdb should detect if the target doesn't support them, # and fall back to using software watchpoints. # # set_board_info gdb_server_prog # This will be the path to the gdbserver program you want to test. # Defaults to "gdbserver". # # set_board_info sockethost # The name of the host computer whose socket is being used. # Defaults to "localhost". Note: old gdbserver requires # that you define this, but libremote/gdbserver does not. # # set_board_info gdb,socketport # Port id to use for socket connection. If not set explicitly, # it will start at "2345" and increment for each use. # # The guts live in gdbserver-support.exp now. load_lib gdbserver-support.exp proc gdbserver_gdb_load { } { return [gdbserver_spawn ""] } proc gdb_reload { } { return [gdbserver_run ""] }
