Beaglebone black开发环境搭建

首先到  http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html    下载工具

先安装SDK （刚开始用的是ubuntu 14  后来由于14把32lib给去了，看官方用的是12就换成了ubuntu12）

1、下载ti-sdk-am335x-evm-07.00.00.00-Linux-x86-Install.bin然后

./ti-sdk-am335x-evm-07.00.00.00-Linux-x86-Install.bin运行

2、接着安装 Toolchain

下载Standalone Linaro Toolchain - Linaro GCC 4.7 2013.03 hard-float toolchain然后解压到
 /home/jdxc/tools/

配置环境变量

jdxc@ubuntu:~$ sudo nano .bashrc

最后一行添加

PATH=$PATH:/home/jdxc/tools/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313$

export PATH

变量生效

 source ~/.bashrc

查看变量

jdxc@ubuntu:~$ echo $PATH

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/ocal/games:/home/tools/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin:/home/jdxc/tools/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin

最后查看一下gcc版本

jdxc@ubuntu:~$ arm-linux-gnueabihf-gcc -v

Using built-in specs.

COLLECT_GCC=arm-linux-gnueabihf-gcc

COLLECT_LTO_WRAPPER=/home/jdxc/tools/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin/../libexec/gcc/arm-linux-gnueabihf/4.7.3/lto-wrapper
