linux下给stm32烧录程序，以imx6ull为例：

1.移植stm32flash

下载地址：stm32flash download | SourceForge.net

$ tar -zxvf stm32flash-0.5.tar.gz
$ cd stm32flash/
$ . /opt/fsl-imx-x11/4.1.15-2.0.0/environment-setup-cortexa7hf-neon-poky-linux-gnueabi 
$ make
$ make install DESTDIR=./__install
$ file usr/local/bin/stm32flash 
usr/local/bin/stm32flash: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=965f73cdeed7052db22429903bb49d32487a4356, not stripped

将usr/local/bin/stm32flash 拷贝到开发板

2.使用方法

使用方法：

$ ./stm32flash 
stm32flash 0.5

ERROR: Device not specified
Usage: ./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

3.烧录

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。
