Hi,
I am trying to program STM32F030C8T6 with STM32CubeIDE. When I try to upload the code, it says the download was successful but then it fails to halt the device. I have tried setting "Reset behaviour" to "None" as other posts have suggested, but that only results to me getting another error with an unknown reason and it telling me to check power and cabling. I have done so, 5 times already and I have measured every part of the circuit with my multimeter. Everything is connected. What I find weird is that a week ago it was working fine. Only as I expanded the firmware by an order of magnitude, it stopped working. What could I do to get rid of this error?
Best regards,
Juhani

After this the LED on the ST-LINK/V2 lights up orange, which I know means communication failed.
