If the file name already exists on the storage medium, the system prompts:
The file is exist,will you recover it? [Y/N]
If you enter
Y
, the existing application file will be overwritten and successfully updated. The
system will use the new application file for next system boot.

Cancel to overwrite the file.
Failed!
In this case, the existing application file will not be overwritten and the file updating will fail.
The size of an application is often over 10 MB. Even if the baud rate is 115200 bps, it will take
about 30 minutes to update the application through a serial interface. Therefore, you are
recommended to update an application through Ethernet.
