硬件：TQ2440 ?64MB內(nèi)存 256MB NandFlash bootloader：U-Boot 2015.04 kernel：linux-4.9 Python:?Python-3.6.0 工具鏈：arm-none-linux-gnueabi-gcc ?4.8.3 概述
現(xiàn)在樹莓派很火，在樹莓派上面用戶可以通過Python來控制板子上面的GPIO資源， 然后我想TQ2440也應(yīng)該做到這一點。 將來根文件系統(tǒng)會通過NFS的方式掛載到開發(fā)板上面。 正文
一、工具鏈
登錄這個網(wǎng)址：http://www.veryarm.com/arm-none-linux-gnueabi-gcc
我們這里使用的是最新的Linux解壓版：arm-2014.05-29，由于TQ2440用的arm9屬于armv4t架構(gòu)，所以在編譯運行于TQ2440上的程序的時候需要給工具鏈傳遞參數(shù)-march=armv4t，為了簡單起見，我們可以用下面的辦法：

即在原來的工具鏈上面做一些軟連接，對arm-linux-gcc/g++/gcc-4.8.3做一些特殊處理： 1 $
cat arm-linux-
gcc
2 #!/bin/
bash
3 arm-none-linux-gnueabi-
gcc -march=armv4t $*
4
5 $
cat arm-linux-g++
6 #!/bin/
bash
7 arm-none-linux-gnueabi-g++ -march=armv4t $*
8
9 $
cat arm-linux-
gcc-
4.8.
3
10 #!/bin/
bash
11 arm-none-linux-gnueabi-
gcc-
4.8.
3 -march=armv4t $*
此外， 還需要注意的是， 將來在制作用于TQ2440的根文件系統(tǒng)的時候拷貝的工具鏈的lib庫的位置：
arm-
2014.05/arm-none-linux-gnueabi/libc/armv4t/lib
而不是：
arm-
2014.05/arm-none-linux-gnueabi/libc/lib
這個用于高于armv4t架構(gòu)的平臺，如exynos4412用的是armv7架構(gòu)。
二、Bootloader
使用的uboot可以到https://github.com/pengdonglin137/u-boot下載，可以參考：
u-boot-2015.04 在tq2440上的移植（使用spl引導(dǎo)u-boot） 將來的分區(qū)稍有變化:
| 1MB ?SPL? ?? |
1MB UBOOT? ?? |
1MB PARAMS? ?? |
5MB KERNEL? ?? | 1MB DTB | 247MB ROOTFS |
由于將來采用NFS掛載根文件系統(tǒng)啟動的方式，下面是bootargs以及bootcmd： bootargs：
noinitrd root=/dev/nfs rw nfsroot=
192.168.
1.101:/nfsroot/rootfs ethmac=1C:6F:
65:
34:
51:7E ip=
192.168.
1.6:
192.168.
1.101:
192.168.
1.1:
255.255.
255.0::eth0:off init=/linuxrc console=ttySAC0,115200n
這里板子的IP是192.168.1.6，HOST的IP是192.168.1.101， 當(dāng)然由于采用了設(shè)備樹的方式， 所以也可以不在uboot里設(shè)置bootargs，而是放到設(shè)備樹的chosen節(jié)點當(dāng)中。
bootcmd： nand read 0x300080000x3000000x500000; nand read 0x320000000x8000000x100000; bootm
0x30008000-
0x32000000 這里會了加快啟動速度， 提前把uImage和dtb文件少些到的nandflash中， 關(guān)于在tq2440上面支持dtb，請參考 ?讓TQ2440也用上設(shè)備樹（1） 三、kernel
可以到https://github.com/pengdonglin137/linux-4.9下載，tq2440_dt分支， 使用方法參考?讓TQ2440也用上設(shè)備樹（1） 燒寫kernel和dtb到nand中：
1 燒寫kernel：
2 mw.b
0x30008000 0xff 0x500000
3 tftp
0x30008000 uImage
4 nand erase
0x300000 0x500000
5 nand
write 0x30008000 0x300000 0x500000
6
7 燒寫dtb：
8 mw.b
0x30008000 0xff 0x100000
9 tftp
0x30008000 dtb
10 nand erase
0x800000 0x100000
11 nand
write 0x30008000 0x800000 0x100000 四、Python

交叉編譯Python-2.7.13到ARM（aarch32）平臺
交叉編譯Python-2.7.13到ARM（aarch32）—— 支持sqlite3 交叉編譯Python-3.6.0到aarch64/aarch32 —— 支持sqlite3 由于上面兩篇博文采用的是qemu模擬的cortex-a9平臺，屬于armv7架構(gòu)，而我們的tq2440是armv4架構(gòu)，所以需要做一些修改。 1 #!/bin/
