如果不改8M Flash的配置 就没问题改成8M的Flash编译出来的固件就报错:

改8M只 改了这个几个地方:
在路径 /trunk/tools/firmware-utils/src/mktplinkfw.c  这个文件里边有个“fw max len”请改成7c0000 (这一步把固件最大限制改成8M),如果是16mflash,请改成fc0000(最大限制改成16m)。
在路径 /trunk/target/linux/ar71xx/files/arch/mips/ar71xx/mach-tl-mr3x20.c 这个文件里边的
rootfs size 从0x290000改成0x690000,art offset 从0x3f0000改成0x7f0000,firmware size从0x3d0000改成0x7d0000(以上是8m的)。



刚刚接触 请明白的指点一下 谢谢先!

楼主,在trunk31835版怎么没有这个路径:
/trunk/target/linux/ar71xx/files/arch/mips/ar71xx/
/trunk/target/linux/ar71xx/files/arch/mips/下只有ath79和include两个目录

那rootfs之类的到哪里去改?

现在已经不需要修改machxxx文件了,只需要修改trunk/tools/firmware-utils/src/mktplinkfw.c,找到3420V1这一行,修改layoutid为“8M“即可,代码上面有8M的分区格式。
