【OpenWRT】—— TL-WR1043ND USB port for expansion of root file system
[i=s] 本帖最後由 角色 於 2013-11-23 20:30 編輯 [/i]因为系统的ROM Flash只有8M，如果要安装很多packages，那么8M Flash就不够了。我们可以通过USB 2.0的port，然后安装flash drive后，通过适当的settings，那么就可以安装很多packages了。

Root file system只有4.78M剩余。 [i=s] 本帖最後由 角色 於 2013-11-23 20:56 編輯 [/i]
1. Install the following packages[code]
