Hi @ikester and welcome to the forum. Sorry to hear that your coworker’s Joulescope is not working for you, and thank you for the detailed information! Based upon the log, it looks like the sensor microcontroller is not communicating with the controller microcontroller. The most likely cause is that the sensor firmware upgrade did not fully complete for some reason. Don’t worry, we can fix this easily! Here are the steps:
- Disconnect your Joulescope
- Start the Joulescope UI
- Select File → Preferences → Device → firmware_update → always .
- Connect your Joulescope and wait for the firmware upgrade to complete
- Select File → Preferences → Device → firmware_update → auto .
Once the firmware update completes, the Joulescope should begin working normally. If the Joulescope is still misbehaving, please respond here and I can help troubleshoot.
