How to connect to stm32f205?

Question

Microelectronics

Good day everyone.
There is a need to connect via jtag / swd to stm32f205
There is a chip soldered with all legs.

There is a Chinese st-link v2

. I assume that I need rst, swclk, swdio 3.3vdd
in the datasheet it is 7, 49, 46, 48 feet,
I'm not sure that I connected correctly and the stm utility also does not see the chip.
Please direct me to the right path and explain where I made a mistake and how to do it right.
Thank you in advance.

Answer 1

Gnd should still be there.
You can upload the firmware to the stone through the bootloader, without a programmer.

Answer 2

If these legs are involved in the circuit, it can interfere, you need to disconnect them from the board tracks. From the software side, in this case, you need to connect under a reset (you can reset it both with a st-link and with your hands).
