STM32F429 Discovery 编译 uclinux

1. 环境要求

1.1 硬件环境

• STM32F429-Disc1 官方开发板
• usb mini线
• usb转串口线（TTL电平）

1.2 软件环境

• Ubuntu 14.04 64位
• STM32 ST-LINK Utility烧写工具

2. 安装交叉工具链

• Download arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu.tar.bz2 from Mentor Graphics
• only arm-2010q1 is known to work; don’t use SourceryG++ arm-2011.03

tar jxvf arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu.tar.bz2
export PATH=$PATH:`pwd`/arm-2010q1/bin

$ arm-uclinuxeabi-gcc -v 会遇到以下问题
arm-uclinuxeabi-gcc: No such file or directory
The toolchain commands are made by 32bit program, and need 32bit running environment.
(My host OS is ubuntu 64bit)

$ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

安装交叉工具链测试正常如下：
