除了Gnode在物理机上的调试外，花时间把下面的事情也调研、试一试。

Hi, I want to debug nic_drv on a real machine using gdb_monitor. But gdb showed this:
(gdb) target remote /dev/ttyS0 Remote debugging using /dev/ttyS0 Ignoring packet error, continuing... warning: unrecognized item "timeout" in "qSupported" response Ignoring packet error, continuing... Ignoring packet error, continuing... Ignoring packet error, continuing...
and my run srcript is: # # Build #
build { core init drivers/timer drivers/pci app/gdb_monitor drivers/uart drivers/nic }
create_boot_directory
# # Generate config #
install_config {
<config verbose="yes"> <parent-provides> <service name="ROM"/> <service name="RAM"/> <service name="IRQ"/> <service name="IO_MEM"/> <service name="IO_PORT"/> <service name="CAP"/> <service name="PD"/> <service name="RM"/> <service name="CPU"/> <service name="LOG"/> <service name="SIGNAL"/> </parent-provides> <default-route> <any-service> <parent/> <any-child/> </any-service> </default-route> <start name="timer"> <resource name="RAM" quantum="1M"/> <provides> <service name="Timer"/> </provides> </start> <start name="uart_drv"> <resource name="RAM" quantum="2M"/> <provides> <service name="Terminal"/> </provides> #is that service name "Terminal" should be "/dev/ttyS0" ? <config> <policy label="gdb_monitor" uart="1"/> </config> </start> <start name="pci_drv"> <resource name="RAM" quantum="2M"/> <provides><service name="PCI"/></provides> </start> <start name="gdb_monitor"> <resource name="RAM" quantum="5M"/> <provides><service name="Nic" /></provides> <config> <target name="nic_drv"/> <preserve name="RAM" quantum="2M"/> </config> </start> </config>}
# # Boot image #
build_boot_image { core init timer ld.lib.so libc.lib.so libc_log.lib.so libc_lock_pipe.lib.so libc_terminal.lib.so uart_drv pci_drv gdb_monitor nic_drv }
set local_port 5555

# connect comport 0 to stdio append qemu_args " -net nic,model=e1000 -net user " append qemu_args " -serial mon:stdio "
# connect comport 1 with TCP port $local_port append qemu_args " -serial chardev:uart " append qemu_args " -chardev socket,id=uart,port=$local_port,host=localhost,server,nowait "
#run_genode_until forever run_genode_until {.*Remote debugging using /dev/ttyS0.*} 30 #run_genode_until {.*Remote debugging using /dev/terminal.*} 30
#exec [terminal] -e "[gdb] bin/nic_drv -ex "target remote localhost:$local_port" " & #exec [terminal] -e "[gdb] bin/nic_drv -ex "target remote localhost:$local_port" " & interact
Is that correct?
Maybe the serial was occupied by the system output?
