修改:

tools/firmware-utils/src/mktplinkfw2.c

static struct flash_layout layouts[] = {{.id= "8Mltq",.fw_max_len= 0x7a0000,.kernel_la= 0x80002000,.kernel_ep= 0x80002000,.rootfs_ofs= 0x140000,}, {.id= "12Mmtk",//这里改了.fw_max_len= 0xC00000,.kernel_la= 0x80000000,.kernel_ep= 0x80000000,.rootfs_ofs= 0x140000,}, {/* terminating entry */}};static struct board_info boards[] = {{.id= "TD-W8970v1",.hw_id= 0x89700001,.hw_rev= 1,.layout_id= "8Mltq",}, {.id= "ArcherC20i",.hw_id= 0xc2000001,.hw_rev= 58,.layout_id= "12Mmtk",//这里改了.hdr_ver= 3,.endian_swap= true,}, {/* terminating entry */}};

过程:首先grep搜索这个错误,有好几个文件有,修改每一个,把文件名打印出来(其实报错的时候有提示文件名,我没注意);

然后把相关的数字、字符打印出来:

ERR("rootfs image is too big from -> mktplinkfw2.c board_id=%s, layout_id=%s, layout->fw_max_len=%d", board_id, layout_id,layout->fw_max_len);

编译一次,我就知道解决方法了,
