WR841V8 openwrt修改为8M固件版本

在openwrt attitude_adjustment编译8M固件需要更改以下两个文件：

1. openwrt/tools/firmware-utils/src/mktplinkfw.c

确保static struct flash_layout layouts[] 有8M的定义，

{

                   .id              = "8M",

                   .fw_max_len    = 0x7c0000,

                   .kernel_la         = 0x80060000,

                   .kernel_ep        = 0x80060000,

                   .rootfs_ofs       = 0x140000,

},

{

                   .id              = "8Mlzma",

                   .fw_max_len    = 0x7c0000,

                   .kernel_la         = 0x80060000,

                   .kernel_ep        = 0x80060000,

                   .rootfs_ofs       = 0x100000,

}

在static struct board_info boards[]中添加，

#define HWID_TL_WR841ND_V8    0x08410008

{

                .id             = "TL-WR841NDv8",

                .hw_id          = HWID_TL_WR841ND_V8,

                .hw_rev         = 1,

                .layout_id      = "8Mlzma",

}

2、  openwrt/target/linux/ar71xx/image/Makefile

Makefiel中找到841以下内容

$(eval $(call SingleProfile,TPLINK-LZMA,$(fs_64kraw),TLWR841NV8,tl-wr841n-v8,TL-WR841N-v8,ttyS0,115200,0x08410008,1,8Mlzma))

将4Mlzma改成的8Mlzma，修改完成以上两个文件后，即可make V=s进行编译，生成的factory.bin即为8M固件版本。
