一、解压安装stm32flash
tar -zxvf stm32flash-0.5.tar.gz
cd stm32flash/
make
sudo make install
二、使用方法
stm32flash [-bvngfhc] [-[rw] filename] [tty_device | i2c_device]
-a bus_address Bus address (e.g. for I2C port)
-b rate Baud rate (default 57600)
-m mode Serial port mode (default 8e1)
-r filename Read flash to file (or - stdout)
-w filename Write flash from file (or - stdout)
-C Compute CRC of flash content
-u Disable the flash write-protection
-j Enable the flash read-protection
-k Disable the flash read-protection
-o Erase only
-e n Only erase n pages before writing the flash
-v Verify writes
-n count Retry failed writes up to count times (default 10)
-g address Start execution at specified address (0 = flash start)
-S address[:length] Specify start address and optionally length for
read/write/erase operations
-F RX_length[:TX_length] Specify the max length of RX and TX frame
-s start_page Flash at specified page (0 = flash start)
-f Force binary parser
-h Show this help
-c Resume the connection (don't send initial INIT)
*Baud rate must be kept the same as the first init*
This is useful if the reset fails
-i GPIO_string GPIO sequence to enter/exit bootloader mode
GPIO_string=[entry_seq][:[exit_seq]]
sequence=[-]n[,sequence]
-R Reset device at exit.
Examples:
Get device information:
stm32flash /dev/ttyS0
or:
stm32flash /dev/i2c-0
Write with verify and then start execution:
stm32flash -w filename -v -g 0x0 /dev/ttyS0
Read flash to file:
stm32flash -r filename /dev/ttyS0
Read 100 bytes of flash from 0x1000 to stdout:
stm32flash -r - -S 0x1000:100 /dev/ttyS0
Start execution:
stm32flash -g 0x0 /dev/ttyS0
GPIO sequence:
- entry sequence: GPIO_3=low, GPIO_2=low, GPIO_2=high
- exit sequence: GPIO_3=high, GPIO_2=low, GPIO_2=high
stm32flash -R -i -3,-2,2:3,-2,2 /dev/ttyS0
三、烧录STM32
使stm32进入串口烧录模式（BOOT1=0，BOOT0=1）
BOOT1=x，BOOT0=0：从主存储器启动，就是我们常说的64K、128K、256K、512K等等的片内的Flash存储器，正常情况下我们一般这么配置，此时BOOT1引脚可以悬空；
BOOT1=0，BOOT0=1：从系统存储器启动，此种启动方式会运行系统存储器内的Bootloader程序，也就是我们常说的ISP程序，这个程序是出厂内置好的，不能更改，系统存储器是一个ROM，我们使用串口下载程序就需要配置为此种启动模式；
BOOT1=1，BOOT0=1：从内置SRAM启动，一般用于调试，当用户需要反复下载调试程序的时候，将程序下载到Flash很慢，此时可以选择下载到SRAM种调试，回提高效率，但是单片机一旦断电，所有程序均丢失，此种启动方式还有一个常用的用途，就是用于解除芯片的读保护功能或者擦除Flash等。
