This means that tests involving printf will 46# fail unles you set this varibale in your baseboard 47# configuration file. 48# 49# set_board_info gdb,no_hardware_watchpoints 1 50# Unles you have a gdbserver that supports hardware watchpoints. 51# FIXME: gdb should detect if the target doesn't support them, 52# and fall back to using software watchpoints. 53# 54# set_board_info gdb_server_prog 55# This will be the path to the gdbserver program you want to test. 56# Defaults to "gdbserver". 57# 58# set_board_info sockethost 59# The name of the host computer whose socket is being used. 60# Defaults to "localhost". Note: old gdbserver requires 61# that you define this, but libremote/gdbserver does not. 62# 63# set_board_info gdb,socketport 64# Port id to use for socket connection. If not set explicitly, 65# it will start at "2345" and increment for each use. 66# 67 68# The guts live in gdbserver-support.exp now. 69 70load_lib gdbserver-support.exp 71 72proc gdbserver_gdb_load { } { 73 return [gdbserver_spawn ""] 74} 75 76proc gdb_reload { {inferior_args {}} } { 77 return [gdbserver_run $inferior_args] 78} 79 80proc gdb_reconnect { } { 81 return [gdbserver_reconnect] 82} 83
