When I downloaded applicaton into flash, I found that it will respond my cmd code if I send cmd code immediately after NRST changing from 0 to 1.
If although I choose 'Boot0(pin) = 1和Boot1(pin) = 0' to flash mode, the stm32f103 will also enter system rom bootstrap code.
It's to say that stm32f103 entering flash mode is bypassing System Rom Bootstrap code.
