1、有3种启动模式：从内置用户FLASH启动、从SRAM内存启动、从系统存储器；
一般用：FLASH启动和从系统存储 ...
知道啊，但是一个BOOT0不能有3中启动模式吧？STM32F1的有BOOT0和BOOT1启动模式管脚，STM32F0只有BOOT0一个，我刚又翻了下手册，“The way to select the boot mode on the F0 family differs from F1 devices. Instead of using
two pins for this setting, F0 gets the nBOOT1 value from an option bit located in the User
option bytes at 0x1FFFF800 memory address. Together with the BOOT0 pin, it selects the
boot mode to the main Flash memory, the SRAM or to the System memory. Ta bl e 3
summarizes the different configurations available for selecting the Boot mode. The BOOT1 value is the opposite of the nBOOT1 option bit.”是不是说STM32F0的BOOT1软件上置0或1？
