本人在编译OpenWrt,可能是选多了,导致最后报错:

[mktplinkfw] *** error: images are too big

意思就是编译出来的内核超出了Flash的容量。

本人注意到第2行的命令:


... mktplinkfw -H 0x07400004 -W 1 -F 4Mlzma -N OpenWrt -V r45594  -s -X 0x40000 -k ...

其中 "4Mlzma" 特别明显。

我们的目标机是改进版的 TP-Link WR740,Flash 8M, RAM 64M。这么说来,这个 "4Mlzma" 应该改成 "8Mlzma" 才合适。

那该在哪儿改呢?

这是我改后的patch文件:

(END)

再编译,就OK了。
