I am using the STM32F407IGT6 chip. However, when I connected JTAG, the symptoms shown in the picture appear. So I have completed the VDD or continuity test. Can you tell me the circuit diagram and the reason?

Welcome @younginpark, to the community!
the pull resistor at BOOT0 have to be connected to GND instead of VDD.
BTW: the pull-up at NRST is not necessary, see the description of NRST in the respective reference manual.
Hope that helps?

I tried connecting BOOT0 to nothing or connecting it to GND.
NRST(R8) is not connected to anything other than a pull-up resistor.
Boot1 is currently in a null state with nothing connected.

Still not working. Do you know why?
