debian下使用ft232为stm32f429i-discovery烧写uboot和uImage

2024-07-07 07:27:39   225人阅读

操作系统：debian

软件: openocd  minicom

硬件:  MiniUSB线、stm32f429i-discovery, WaveShare FT232串口模块(可以在淘宝上买到)

关于openocd的配置可以参看我的博文： 《debian下烧写stm32f429I discovery裸机程序》

u-boot源码下载：

git clone https://github.com/EmcraftSystems/u-boot.git

linux源码下载：

git clone https://github.com/EmcraftSystems/linux-emcraft.git

将u-boot和linux源码下载下来后进行编译可以得到uboot和linux二进制文件。

也可以直接下载已经编译好的uboot和linux内核（下载地址）。

我暂时先选择直接下载编译好的uboot(u-boot.bin)和linux内核（下载地址，名为networking.uImage），然后下载到/home/host/soft/stm32f429i-discovery/文件夹下。

 

将FT232的USB口与pc相连。

然后将stm32f429i-discovery与FT232连接（参考链接），连线方式如下:

VDD与VDD相连，GND与GND相连。 PA10(USART_RX)连接FT232的TXD,PA9（USART_TX)链接FT232的RXD。

 

连好后，执行下面命令：

$ dmesg | tail -n 18

[ 7937.764668] usb 1-1.1: USB disconnect, device number 6

红色字体部分是插入ft232模块后的系统信息，现在可以通过/dev/ttyUSB0来访问ft232串口。

 

参考文章《debian下烧写stm32f429I discovery裸机程序》

在一个控制台执行sudo minicom,配置成/dev/ttyUSB0,115200,8N1,No Harware Flow Control,No Software Flow Control.

另一个控制台下执行下面命令：

sudo openocd -f  interface/stlink-v2.cfg -f board/stm32f429discovery.cfg

再开一个控制台执行下面的命令：

telnet localhost 4444
halt
flash probe 0
flash info 0
flash write_image erase  /home/host/soft/stm32f429i-discovery/u-boot.bin 0x08000000 bin
reset run

其中可以用flash banks查看flash信息：

> flash banks
#0 : stm32f4x.flash (stm32f2x) at 0x08000000, size 0x00200000, buswidth 0, chipwidth 0

flash映射地址位于0x08000000，前面的命令用来将uboot也烧写到这个位置。

 

再参考文章《Loading Linux Images over UART》将内核下载到内存中。

然后就可以在运行minicom的控制台下按任意键看到下面的信息：

U-Boot 2010.03-linux-cortexm-1.12.1 (Jan 21 2014 - 10:22:44)

Out:   serial

 在uboot下执行loady,然后按下快捷键ctrl+A，再按下z键，再按下S键，选择ymodem,然后按g键，输入文件夹路径/home/host/soft/stm32f429i-discovery，多次按下‘向下’键，

直到光标到networking.uImage处，然后按下空格键，同时要保证最下面的光标位于Okay处（如果不在Okay处，可以左右键找到将其移动到Okay处），然后按下回车键，

就会开始传输文件了，等传输完毕后，屏幕中间会显示下面的信息：

Transfer complete                                       
READY: press any key to continue...

按下任意键,显示下面信息：

## Ready for binary (ymodem) download to 0xD0007FC0 at 115200 bps...                                                       
Cdem - CRC mode, 12442(SOH)/0(STX)/0(CAN) packets, 5 retries
## Total Size      = 0x00184ba0 = 1592224 Bytes

然后在uboot下执行下面命令：

STM32F429-DISCO> bootm 0xd0007fc0
