Stm32CubeProgrammer not connecting (no error msg) using ST-LINK V2 dongle and Lora E5 mini board
14:31 29 Apr 2022

I've tried countless settings in an attempt to program my stm32 board. The main tutorial I followed is https://wiki.seeedstudio.com/LoRa_E5_mini/.

I have connected a USB st-link v2 dongle to my laptop with pins SWDIO, SWCLK, GND correctly wired to the STM32 board.

For power the board is also connected to a usb port via its type c connector.

Serial comms over usb work, updating the st link firmware works and stm32cube programmer finds the st link device:

I now press the reset button, hold it, click on Connect, release the reset button after 3 seconds and then.. absolutly nothing happens and no error message appears.

I've tried the same thing with ST-LINK utility. When holding the reset button the LED on the st link dongle starts flashing, but whenever I release the button I get this:

I was not able to find the same issue on google, since everyone else is getting error messages if it doesn't work.

Has anyone run into the same problem? What part could be the issue?
