Why does the firmware on stm32 not start?

Question

Microcontrollers

Hello.
The second day I suffer trying to start this controller. I do everything from this article cxem.net/mc/mc172.php. I just upload via CP2102 from Arduino pro mini. Connected and rearranged the jumper so . I uploaded the firmware via flash loader demo. I rearrange the jumper, disconnect the programmer, Connect USB and LEDs. Does not work...

I think that suffering with the CP2102 at a cost close to ST-LINK is pointless. In general, if you really want to, then you should check the nutrition, this time. Then remember that after closing the jumpers, you need to restart the power controller. Flash. And then, after the firmware, disconnect from the power supply, change the jumpers to the "work from flash" mode and connect the power, enjoying life.
