I am trying to program a stm32f030cct6 with a ST-Link v2. When I try to connect using CubeProgramer says: "Tarjet not found". I connect to NREST, CLK and SWDIO, I'm measuring the signals with an oscilloscope and SWDIO is in PullDown when it should be in PullUp, as it says in the datasheet. Note that the clock takes some more time to start toggle, about 200 ms. I don't know what could be the error

Thanks. enter image description here

I try to connect NRST via the button to GND. I press the button and then start "Connect" and release the button after about a second to do a "Mass Erase" and nothign change

  • could be the program that's already in MCU repurposes the pin before debugger connects to it, among other possible problems. Connect using cubeprogrammer while physically holding reset button (reset permanently pulled low). It's called "connect under reset". Then you should be able to mass erase. Also, please, include picture into the post – Ilya Aug 31 '23 at 10:58
