How to unlock STM32G031J6M6 (STM32G0316-DISCO)?

[spacemishka]

Hi,

today i got a STM32G0316-DISCO and totally forgot to setup serialwire. All Pins except PIN6 where configured as GPIO-Output. No i can't connect to the MCU. I tried most of the hints regarding "connect under reset" but no success. I had also one try with my J-Link, but no success. Is it possible to use JTAG to get it back working?

thanks

Peter

Try disconnect and connect Idd jumper with connection attempt
