While working on my project today, my Cerberus board stopped responding over USB, it would run it’s per-minute clock, and post data to my web service, but would not accept a connection from VS or Fez Config. I fired up STDFU as per https://www.ghielectronics.com/docs/46/fez-cerb-family-developers-guide and it responded fine in DFU mode, I followed the steps to erase and download the cerb family DFU, and when it resets I have a green light but still no response across USB (I disconnected all other modules aside from the USB SP one).
Can anyone advise on the next steps for troubleshooting this?
Step 1 I always use to help troubleshoot is looking in Device Manager to see what presents itself to the OS, and in what mode that implies. But the bad news is that if you’ve reflashed the firmware in DFU mode, then you should be able to see the device in MFDeploy/VS to deploy against; sounding like possible hardware issue. Any chance you had a wiring glitch around the time things started going pearshaped ?
