Hi Jacob,
the most common issues are next:
- SDcard is not inserted correctly or in the correct slot
- SDcard is corrupted/damaged. Please double check that sdcard has been flashed correctly (content is present) and you can try also a different SDcard
- Missing driver, you may install CP210x driver
- Minicom config, please check following document All Boards Serial Console
- Terminal is closed without closing connection and it gets stuck. In this case you need to close the terminal, unplug the board, plug again and restart terminal. This will make sure that the resource is free to start a new connection.
Regards,
Carlos
