Do you have an ST chip or a knock off of unknown origin?

[Sflu.1]

there is no stm32f407 fackery topics on the web. there is ST trade mark on the chip I see. And I have debuged it in keil, it can run.

I am a freshman on stm32 and cubeide, could you tell me what is it doing reading addr 0x07070700 and 0x07070723. ​
