由于pogoplug没有视频输出，所以如果在启动过程中出现问题，很难判断是什么问题，netconsole解决了这个问题，启动的信息stream到network上的另外一台电脑。

mhassan.me/2013/08/30/...goplug-v2/

1.update uboot
mhassan.me/2012/06/27/...goplug-v2/

2. 在pogoplug上设置启动变量
# fw_setenv serverip 192.168.1.110
# fw_setenv ipaddr 192.168.1.100
# fw_setenv if_netconsole 'ping $serverip'
# fw_setenv start_netconsole 'setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
# fw_setenv preboot 'run if_netconsole start_netconsole'

192.168.1.110是monitor的ip
192.168.1.100是你pogoplug的ip

3.nc -lu 6666 on your 192.168.1.110

4. restart your pogoplug,

5. watching your monitor, will show:
