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 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.bz2export 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：

3. 安装romfs工具

$ sudo apt-get install genromfs

4. stm32f429 linux download, build and install

4.1 下载源码

$ git clone http://github.com/jserv/stm32f429-linux-builder

或者

$ git clone http://github.com/lisongze2016/stm32f429-linux-builder

4.2 编译

$ cd stm32f429-linux-builder$ make$ make install

5. 烧写

5.1 用STM32 ST-LINK Utility烧写工具烧写:

addr	bin	编译生成路径
0x08000000	u-boot.bin	out/uboot/u-boot.bin
0x08020000	xipuImage.bin	out/kernel/arch/arm/boot/xipuImage.bin
0x08120000	romfs.bin	out/romfs.bin

5.2 serial connections.

STM32 PC11 --> Cable connector Orange Txd(PC)

STM32 PC10 --> Cable connector Yellow Rxd(PC)

5.3 Terminal settings:

Baud rate: 115200

Data: 8 bit

Parity: none

Stop: 1 bit

Flow control: none

5.4 Booting console output.
