为什么要首先刷那个Bootloader？
小白初学，不太明白原理，为什么要先刷那个Bootloader才能再使用Arduino呢？平常的启动，好像不用经过boot0的那个系统区吧？
但刷过后，每次启动，都首先是boot0那个刷进去的内容先运行
Arduino after power on , bootloader will check USB if there is code available for uploading .
If not then program counter transf to code inside flash.
If there is code available from IDE and it will transfer from developing system to target board.
Draw back is some of the flash memory is used for the bootloader.
