aducm330 not responding

While testing, my aducm330 randomly stopped responding. I was testing some code which was working fine, so I don't think that caused it.

On one hand, it is definitely not in downloader mode, as it does not respond to id requests, meaning I cannot program it using a usb dongle. On the other, I cannot access it through Keil, because it gives me the "no cortex-m device found in jtag chain" error.

Is there anything I can do to salvage it, or is a lost cause. If it is, what can cause this kind of malfunction (for future reference)?

 

Thank you in advance!
