If the minicom file is garbled, enter gedit. bashrc, add the export lang = zh_CN.UTF-8 at the end to modify the system language and enter .. bashrc make the change take effect, and use echo $ Lang to check whether the change is OK; or directly enter export lang = zh_CN.UTF-8 in the console (it is not valid after restart); if it still cannot be resolved, please try to replace the USB-to-serial line or re-weld the solder joint.
