编译结束！！
所需文件：
从720工具链中mips-gcc720-glibc229-r5.1.4/mips-linux-gnu/libc/uclibc/lib复制两个库文件（ld-uClibc-mipsn8.so.0、libc.so.0）到库文件系统的/lib下（mtd-utils-2.1.0/lib/）
mtd-utils的交叉编译，压缩包中是已经使用720工具链交叉编译好的，可直接使用，也可自己编译，方法参考如下:

查看分区：cat /proc/mtd
查看挂接主次设备号：cat /proc/partitions
擦除要烧写的分区：
flash_eraseall /dev/mtd5
nandwrite烧写(先擦除烧写的分区)：
./nandwrite -a /dev/mtd5 data.img
flashcp烧写到分区：
./flashcp -v data.img /dev/mtd5
（PS：nandwrite、flash_eraseall等执行文件位于__install/sbin文件夹下）
flash_eraseall擦除之后flashcp烧写失败解决办法：https://blog.csdn.net/weixin_43615992/article/details/126721414
