Programming STM32L552ZE via SWDIO and SWCLK
Hi,
I have made a board with STM32L552ZE and i cannot manage to connect to it realiably with ST-LINK via SWDIO and SWCLK. I have tried everything from connecting nrst via a 10k resistor to 3v3 to holding the NRST pin in reset while hitting the ERASE button in ST-LINK(in this last case i have managed to connect to it once or twice but nothing realiable). I have tried Connect Under Reset also nothing. I am working with STM MCU all the time but with this one I am having issues....what should I verify next or what should I be aware of next? Thank you for your help guys!
