本人在編譯OpenWrt，可能是選多了，導(dǎo)致最后報錯：

[mktplinkfw] *** error: images are too big
意思就是編譯出來的內(nèi)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" 特別明顯。
我們的目標(biāo)機是改進(jìn)版的 TP-Link WR740，Flash 8M， RAM 64M。這么說來，這個 "4Mlzma" 應(yīng)該改成 "8Mlzma" 才合適。
那該在哪兒改呢？
這是我改后的patch文件：

再編譯，就OK了。
