移植Python3到TQ2440（一）
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
概述
现在树莓派很火，在树莓派上面用户可以通过Python来控制板子上面的GPIO资源， 然后我想TQ2440也应该做到这一点。 将来根文件系统会通过NFS的方式挂载到开发板上面。

一、工具链
登录这个网址：http://www.veryarm.com/arm-none-linux-gnueabi-gcc
我们这里使用的是最新的Linux解压版：arm-2014.05-29，由于TQ2440用的arm9属于armv4t架构，所以在编译运行于TQ2440上的程序的时候需要给工具链传递参数-march=armv4t，为了简单起见，我们可以用下面的办法：
( pengdl@ubuntu | ~/Study/cross_compile/arm-2014.05/bin | Remote:True )

即在原来的工具链上面做一些软连接，对arm-linux-gcc/g++/gcc-4.8.3做一些特殊处理：
$cat arm-linux-gcc
#!/bin/bash
arm-none-linux-gnueabi-gcc -march=armv4t $* $cat arm-linux-g++
#!/bin/bash
arm-none-linux-gnueabi-g++ -march=armv4t $* $cat arm-linux-gcc-4.8.
#!/bin/bash
arm-none-linux-gnueabi-gcc-4.8. -march=armv4t $*
此外， 还需要注意的是， 将来在制作用于TQ2440的根文件系统的时候拷贝的工具链的lib库的位置：
arm-2014.05/arm-none-linux-gnueabi/libc/armv4t/lib
而不是：
arm-2014.05/arm-none-linux-gnueabi/libc/lib
这个用于高于armv4t架构的平台，如exynos4412用的是armv7架构。
二、Bootloader
使用的uboot可以到https://github.com/pengdonglin137/u-boot下载，可以参考：
将来的分区稍有变化:
| 1MB SPL | 1MB UBOOT | 1MB PARAMS | 5MB KERNEL | 1MB DTB | 247MB ROOTFS |
由于将来采用NFS挂载根文件系统启动的方式，下面是bootargs以及bootcmd：
bootargs：
noinitrd root=/dev/nfs rw nfsroot=192.168.1.101:/nfsroot/rootfs ethmac=1C:6F::::7E ip=192.168.1.6:192.168.1.101:192.168.1.1:255.255.255.0::eth0:off init=/linuxrc console=ttySAC0,115200n
这里板子的IP是192.168.1.6，HOST的IP是192.168.1.101， 当然由于采用了设备树的方式， 所以也可以不在uboot里设置bootargs，而是放到设备树的chosen节点当中。
bootcmd：
nand read 0x300080000x3000000x500000; nand read 0x320000000x8000000x100000; bootm 0x30008000-0x32000000
这里会了加快启动速度， 提前把uImage和dtb文件少些到的nandflash中， 关于在tq2440上面支持dtb，请参考 讓TQ2440也用上設備樹（1）
三、kernel
可以到https://github.com/pengdonglin137/linux-4.9下载，tq2440_dt分支， 使用方法参考 讓TQ2440也用上設備樹（1）
烧写kernel和dtb到nand中：
烧写kernel：
mw.b 0x30008000 0xff 0x500000
tftp 0x30008000 uImage
nand erase 0x300000 0x500000
nand write 0x30008000 0x300000 0x500000 烧写dtb：
mw.b 0x30008000 0xff 0x100000
tftp 0x30008000 dtb
nand erase 0x800000 0x100000
nand write 0x30008000 0x800000 0x100000
四、Python
参考
由于上面两篇博文采用的是qemu模拟的cortex-a9平台，属于armv7架构，而我们的tq2440是armv4架构，所以需要做一些修改。
SQlite
#!/bin/bash ../sqlite-autoconf-/configure --host=arm-none-linux-gnueabi \
--prefix=`pwd` \
CFLAGS="-march=armv4t" \
CPPFLAGS="-march=armv4t" \
LDFLAGS="-march=armv4t" make -j4
make install
Readline
#!/bin/bash ../readline-7.0/configure --host=arm-none-linux-gnueabi \
--prefix=`pwd` \
CFLAGS="-march=armv4t" \
CPPFLAGS="-march=armv4t" \
LDFlAGS="-march=armv4t" make -j4
make install
Termcap
配置:
#!/bin/bash ../termcap-1.3./configure --host=arm-none-linux-gnueabi \
--prefix=`pwd`
修改Makefile：
CC = arm-none-linux-gnueabi-gcc
AR = arm-none-linux-gnueabi-ar
RANLIB = arm-none-linux-gnueabi-ranlib
... ...
CFLAGS = -g -march=armv4t
然后 make && make install
Python3
配置：
#!/bin/bash ../Python-3.6./configure \
--host=arm-linux \
--build=armv4 \
--prefix=`pwd` \
--enable-ipv6 \
--enable-shared \
ac_cv_file__dev_ptmx="yes" \
ac_cv_file__dev_ptc="no" \
LDFLAGS="-L/home/pengdl/Study/tq2440/Python/SQlite/tq2440/lib \
-L/home/pengdl/Study/tq2440/Python/Readline/tq2440/lib \
-L/home/pengdl/Study/tq2440/Python/Termcap/tq2440" \
CPPFLAGS="-I/home/pengdl/Study/tq2440/Python/SQlite/tq2440/include \
-I/home/pengdl/Study/tq2440/Python/Readline/tq2440/include"
别忘了修改Modules/Setup文件，然后执行 make && make install即可。
五、根文件系统
参考博客 用Qemu搭建aarch32学习环境
下面是制作根文件系统的脚本：
#!/bin/bash sudo rm -rf rootfs
sudo rm -rf tmpfs
sudo rm -rf ramdisk* sudo mkdir rootfs
sudo cp ../busybox-1.24./_install/* rootfs/ -raf sudo mkdir -p rootfs/proc/
sudo mkdir -p rootfs/sys/
sudo mkdir -p rootfs/tmp/
sudo mkdir -p rootfs/root/
sudo mkdir -p rootfs/var/
sudo mkdir -p rootfs/mnt/ sudo cp etc rootfs/ -arf
sudo mkdir -p rootfs/lib sudo cp -arf /home/pengdl/Study/cross_compile/arm-2014.05/arm-none-linux-gnueabi/libc/armv4t/lib/*.so* rootfs/lib #Python3
sudo mkdir -p rootfs/usr
pushd rootfs/usr
sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/lib .
sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/include .
sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/bin .
sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/share .
sudo arm-none-linux-gnueabi-strip lib/python*
popd #sqlite3
sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/bin/* rootfs/bin
sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/include/* rootfs/include
sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/lib/* rootfs/lib
sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/share/* rootfs/usr/share
sudo arm-linux-strip rootfs/bin/sqlite3 #readline
sudo cp -raf /home/pengdl/Study/tq2440/Python/Readline/tq2440/include/* rootfs/include
sudo cp -raf /home/pengdl/Study/tq2440/Python/Readline/tq2440/lib/* rootfs/lib sudo rm -f rootfs/lib/libwv* rootfs/lib/libuniconf*
sudo rm -f rootfs/lib/*.a
sudo rm -f rootfs/lib/*.la
sudo arm-none-linux-gnueabi-strip rootfs/lib/* sudo mkdir -p rootfs/dev/
sudo mknod rootfs/dev/tty1 c 4 1
sudo mknod rootfs/dev/tty2 c 4 2
sudo mknod rootfs/dev/tty3 c 4 3
sudo mknod rootfs/dev/tty4 c 4 4
sudo mknod rootfs/dev/console c 5 1
sudo mknod rootfs/dev/null c 1 3 sudo rm /nfsroot/rootfs_bak -rf
sudo mv /nfsroot/rootfs /nfsroot/rootfs_bak
sudo cp ./rootfs /nfsroot/ -raf
其中的etc目录可以到这里下载：http://files.cnblogs.com/files/pengdonglin137/etc.zip
