This is a specific question Programming a new IC STM32030 using an ST-Link and STM32CubeProgrammer. I have spent considerable time trying to understand why I cannot connect to my stm32. I have attempted to connect and program through STM32CubeIDE al

[BMcCa.1]

The St_link registers itself and the serial is updated etc. however when I attempt to connect to the newly soldered chip, I get the message that "No STM32 target found".

Am I attempting to program this chip incorrectly by using the SWDIO, GND, SWCLK and 3.3v single wire connections.

There is little to no examples I have found to do this, as most examples are for the premade nucleo boards etc.

Any advice would be greatly appriceated, or a reference to the correct data.

At least GND and 3.3V appears to be working, because ST-Link is able to detect it.

Have you tried other settings, like connect under reset, or lower frequency?

[BMcCa.1]

I haven’t tried different frequencies, I can give that a try.

As for doing it under reset. Would that be done through grounding the reset pin?

[berendi]

Yes, the flashing or debugging session will be started with reset pulled low. Of course you have to connect it to the ST-Link for it to work. Useful if the software messes up GPIO configuration (intentionally or by mistake). Though it should not be necessary with a brand new chip.
