pyboard is dead, why

HI,ALL,
I test pyb.stop() at the end of my main.py, but maybe it make my pyboard dead, because it becomes to be "an unknown device". I have redownloaded firmware of micropython, but no use. accturely, only DFU mode can be recognized.

Re: VCC-GND STM32F407VET6 dev board

I set the board to DFU mode , and download the flash using:

It worked in MACos, but met a driver trouble in Win7 X64. It can be read as a mass strorage, but the VCP cannot work.
What is the problem?

Re: How to use scipy in micropython

Thanks for your reply. Now I have to code my own array/fft/fir and so on. They are the keys of my job.
