接着前一篇博文。

在上一篇博文中我们用NFS挂载根文件系统的方式启动了系统，接下来我们把移植了Python3的根文件系统固化到NandFlash中，但是由于linux-4.9目前不支持Yaffs2文件系统，所以我们用Jiffs2文件系统。

下面我们分为几部分：

1、移植mtd-utils工具

2、固化根文件系统到NandFlash中

3、支持Telnet

平台

硬件：TQ2440 64MB内存 256MB NandFlash

bootloader：U-Boot 2015.04

kernel：linux-4.9

Python: Python-3.6.0

工具链：arm-none-linux-gnueabi-gcc 4.8.3

正文

一、移植mtd-utils工具

mtd-utils提供了大量的用于操作Flash的工具，这里需要首先下载编译一些依赖包。

zlib-1.2.11

下载： http://files.cnblogs.com/files/pengdonglin137/zlib-1.2.11.tar.gz 或者 mtd-utils-2.0.0.tar.bz2

下面是编译脚本：

 #!/bin/bash

 export CC=arm-linux-gcc

 ../configure --prefix=`pwd` \

         --shared

然后编译make && make install

lzo-2.10

下载 http://files.cnblogs.com/files/pengdonglin137/lzo-2.10.tar.gz 或者 http://www.oberhumer.com/opensource/lzo/download/

编译脚本：

 #!/bin/bash

 ../configure --host=arm-linux \

         CC="arm-linux-gcc" \

         --prefix=`pwd`

然后编译make && make install

e2fsprogs-1.43.4

下载 http://files.cnblogs.com/files/pengdonglin137/e2fsprogs-1.43.4.tar.gz 或者 https://sourceforge.net/projects/e2fsprogs/files/latest/download?source=files

编译：

 #!/bin/bash

 ../configure --host=arm-linux \

         CC="arm-linux-gcc" \

         --prefix=`pwd`

编译 make && make install

mtd-utils

下载：http://git.infradead.org/mtd-utils.git 或者 http://files.cnblogs.com/files/pengdonglin137/mtd-utils-v2.tar.gz

编译：

 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2 | Remote:True )

 $./autogen.sh

 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2 | Remote:True Ret:  @ :: )

 $cd build_tq2440/

 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2/build_tq2440 | Remote:True )

 $./mk.sh

编译脚本：

 #!/bin/bash

 export CC=arm-linux-gcc

 export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43./build_tq2440/lib/uuid

 ../configure --host=arm-linux \

         --prefix=`pwd` \

         LDFLAGS="-L/home/pengdl/Study/tq2440/MTD_UTILS/zlib-1.2.11/build_tq2440/lib \

         -L/home/pengdl/Study/tq2440/MTD_UTILS/lzo-2.10/build_tq2440/lib \

         -L/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43./build_tq2440/lib" \

         CPPFLAGS="-I/home/pengdl/Study/tq2440/MTD_UTILS/zlib-1.2.11/build_tq2440/include \

         -I/home/pengdl/Study/tq2440/MTD_UTILS/lzo-2.10/build_tq2440/include \

         -I/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43./build_tq2440/include"

 make -j4

 make install

在sbin下面会生成我们需要的工具，这里我们只要flash_eraseall和flash_erase两个工具，将这两个工具拷贝到根文件系统的/bin下面。

二、固化根文件系统到NandFlash

先把前一篇博文中生成的rootfs目录进行压缩：

sudo tar -czf rootfs.tar.gz rootfs

然后将rootfs.tar.gz拷贝到根文件系统下面，然后启动系统，烧写系统：

 flash_eraseall  /dev/mtd5

 mount -t jffs2 /dev/mtdblock5 /mnt

 tar -xf rootfs.tar.gz /mnt

 cd /mnt

 mv rootfs/* .

 rm -r rootfs

然后修改uboot的bootargs参数：

noinitrd root=/dev/mtdblock5 rw rootfstype=jffs2 console=ttySAC0,115200n init=/linuxrc

三、支持telnet

参考博文 http://www.cnblogs.com/pengdonglin137/p/5028802.html

四、开机log
