移植Python3到TQ2440(二)
平台
正文
一、移植mtd-utils工具
- zlib-1.2.11
#!/bin/bash export CC=arm-linux-gcc ../configure --prefix=`pwd` \
--shared
然后编译make && make install
- lzo-2.10
#!/bin/bash ../configure --host=arm-linux \
CC="arm-linux-gcc" \
--prefix=`pwd`
然后编译make && make install
- e2fsprogs-1.43.4
#!/bin/bash ../configure --host=arm-linux \
CC="arm-linux-gcc" \
--prefix=`pwd`
编译 make && make install
- mtd-utils
( 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` \

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:
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
四、开机log
