This test framework does not 41# address the issue, so it's best to set this variable 42# in your baseboard configuration file. 43# FIXME: there's no reason why the test harness couldn't 44# pass commandline args when it spawns gdbserver. 45# 46# set_board_info gdb,noinferiorio 1 47# Neither the traditional gdbserver nor the one in libremote 48# can presently capture stdout and relay it to GDB via the 49# 'O' packet. This means that tests involving printf will 50# fail unles you set this varibale in your baseboard 51# configuration file. 52# 53# set_board_info gdb,no_hardware_watchpoints 1 54# Unles you have a gdbserver that supports hardware watchpoints. 55# FIXME: gdb should detect if the target doesn't support them, 56# and fall back to using software watchpoints. 57# 58# set_board_info gdb_server_prog 59# This will be the path to the gdbserver program you want to test. 60# Defaults to "gdbserver". 61# 62# set_board_info sockethost 63# The name of the host computer whose socket is being used. 64# Defaults to "localhost". Note: old gdbserver requires 65# that you define this, but libremote/gdbserver does not. 66# 67# set_board_info gdb,socketport 68# Port id to use for socket connection. If not set explicitly, 69# it will start at "2345" and increment for each use. 70# 71 72# The guts live in gdbserver-support.exp now. 73 74load_lib gdbserver-support.exp 75 76proc gdbserver_gdb_load { } { 77 return [gdbserver_spawn ""] 78} 79 80proc gdb_reload { } { 81 return [gdbserver_run ""] 82} 83 84proc gdb_reconnect { } { 85 return [gdbserver_reconnect] 86} 87
