DOPI Rootfs

DOPI使用的rootfs文件系统

编译

如果根路径下不存在dev,sys,proc文件夹,则创建(git不记录空文件夹)

mkdir -p ./rootfs_uclibc/dev
mkdir -p ./rootfs_uclibc/sys
mkdir -p ./rootfs_uclibc/proc

根据flash类型进行选择编译,flash为nand时,以开发板使用的flash为例,参数如下:

./mkyaffs2image100 ./rootfs_uclibc yaffs2-rootfs.img 1 2

参数说明:

mkyaffs2 {dir} {image} {pagesize} {ecctype}

image the output file to hold the image
pagesize the page size to be converted
0 | 512 512 Bytes pagesize
1 | 2k 2K Bytes pagesize
2 | 4K 4K Bytes pagesize
3 | 8K 8K Bytes pagesize
4 | 16K 16K Bytes pagesize
ecctype ECC type
0 | none no ecc
1 | 1bit used 1bit/512 ecc
2 | 4bit used 4bit/512 ecc
3 | 8bit used 8bit/512 ecc
4 | 24bit used 24bit/1k ecc
5 | 40bit used 40bit/1k ecc
6 | 64bit used 64bit/1k ecc

flash为nor时,64MB示例:

./mkfs.jffs2 -d ./rootfs_uclibc -l -e 0x10000 -o rootfs.jffs2
