Tested on NUCLEO-F401RE (stm32f401re). It has the slowest Fcpu (adapter speed) in the STM32F4 series.

It seems that the original adapter speed for reset-init and reset-start is too high for my board.  I've reduced the speed  to get rid of the errors. Technically this should work on all other STM32F4 boards as they all have higher Fcpu.
