Neither Keil nor stlink can recognize the chip.

That means there is a problem with the SWD connection.

It's so simple it should have been solved long ago.

Check whether the chip is powered normally. Some STlink downloaders cannot power the chip.

Haha, I just solved this problem. First pull the reset pin to the bottom to see if it can be scanned.

Please pay attention to the advice of dcexpert . Do not simply think of SWD connection as a hardware connection problem. There are also configuration and initialization problems. The above errors will also occur without initialization.
