Code generation error

When trying to upload code to my STM, I receive this error message.

There is likely something wrong with your board’s power supply:

Info : Target voltage: 1.933289

Have you successfully used this board in the past? How are you powering the board? Are you using the NUCLEO-F303RE board (per the error message) or are you using something else? Refer to the section 7.5 of the UM1724 for different voltage supply options.

Another possible cause is missing STLINK drivers. This is the case on some Windows machines. A workaround is to install STM32 Cube IDE (this will also install the necessary drivers).

I am also receiving this type of error.

The interface firmware FAILED to reset/halt the target MCU
