创建分区非常简单，直接修改DTS文件：target/linux/samsung/dts/TQ210.dts
&nand {
status = "okay";
nand-ecc-mode = "soft";
partition@0 {
label = "boot";
reg = <0x0 0x40000>; /* 246KB */
read-only;
};
partition@40000 {
label = "kernel";
reg = <0x40000 0x300000>; /* 3MB */
};
partition@340000 {
label = "rootfs";
reg = <0x340000 0x3fcc0000>; /* 1020MB */
};
};
这里给boot分区添加了只读属性：read-only
重新编译固件
make -j4
运行内核，将看到如下信息
