可钦：

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

#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?
