移植Python3到TQ2440(二)
平台
正文
一、移植mtd-utils工具
- zlib-1.2.11
1 #!/bin/bash 2 3 export CC=arm-linux-gcc 4 5 ../configure --prefix=`pwd` \ 6 --shared
然后编译make && make install
- lzo-2.10
1 #!/bin/bash 2 3 ../configure --host=arm-linux \ 4 CC="arm-linux-gcc" \ 5 --prefix=`pwd`
然后编译make && make install
- e2fsprogs-1.43.4
1 #!/bin/bash 2 3 ../configure --host=arm-linux \ 4 CC="arm-linux-gcc" \ 5 --prefix=`pwd`
编译 make && make install
- mtd-utils
1 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2 | Remote:True ) 2 $./autogen.sh 3 4 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2 | Remote:True Ret: 130 @ 22:31:03 ) 5 $cd build_tq2440/ 6 7 ( pengdl@ubuntu | ~/Study/tq2440/MTD_UTILS/mtd-utils-v2/build_tq2440 | Remote:True ) 8 $./mk.sh
编译脚本:
1 #!/bin/bash 2 3 export CC=arm-linux-gcc 4 export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43.4/build_tq2440/lib/uuid 5 6 ../configure --host=arm-linux \ 7 --prefix=`pwd` \ 8 LDFLAGS="-L/home/pengdl/Study/tq2440/MTD_UTILS/zlib-1.2.11/build_tq2440/lib \ 9 -L/home/pengdl/Study/tq2440/MTD_UTILS/lzo-2.10/build_tq2440/lib \ 10 -L/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43.4/build_tq2440/lib" \ 11 CPPFLAGS="-I/home/pengdl/Study/tq2440/MTD_UTILS/zlib-1.2.11/build_tq2440/include \ 12 -I/home/pengdl/Study/tq2440/MTD_UTILS/lzo-2.10/build_tq2440/include \ 13 -I/home/pengdl/Study/tq2440/MTD_UTILS/e2fsprogs-1.43.4/build_tq2440/include" 14 15 make -j4 16 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
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:
1 flash_eraseall /dev/mtd5 2 mount -t jffs2 /dev/mtdblock5 /mnt 3 tar -xf rootfs.tar.gz /mnt 4 cd /mnt 5 mv rootfs/* . 6 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
四、开机log
