Today I noticed that the ST-Link on STM32F0Discovery board lost the connection with the MCU after about 10 seconds. I tried another programmer and that worked perfectly so something wrong with the Discovery board. I tried to connect to target with STLink Utility but it can't establish the connection.
I tried to reflash the firmware of the STLink but I get a message about the content of STLink is corrupt:
Device manager shows the STLink, I can program target controllers but I can not debug these.
Can I recover the STLink somehow? I tried to reset the controller by SB13 but the result was the led toggled red by seconds and the STLink upgrade can't see the controller.
