No device found on target

Hi, I mistakenly used the pin for swd on my F446RE for other purposes and now it does not connect through st link.

Can anyone guide me through a solution for it? The only thing I can do now is update the board. The two leds are always red.

What board?

If NRST is connected, Select Mode: Under reset and Reset mode: Hardware reset in STM32CubeProgrammer. Then connect and erase the flash to recover the chip. These options are also in STM32CubeIDE in the run/debug configuration.

Did you do what I suggested? What happened? If it did not work, show relevant logs and error messages.

Hmm, If I recreate this issue (reassign SWD pins), I can connect to a Nucleo-64 board with these settings. If that is the only issue, I don't know why would be seeing different behavior. I assume you haven't modified the jumpers or solder bridges on the board at all?

No modifications at all. I searched and some websites told to reset using the boot pin but I don't know how to do it properly. It said to connect boot to 3.3v pin and then hold reset and then try to connect.
