Arduino Uno WiFi Rev2 upload

Arduino Uno WiFi Rev2
But when uploading I get this error ?
any help ar welcome

Sketch uses 1510 bytes (3%) of program storage space. Maximum is 48640 bytes.
Global variables use 22 bytes (0%) of dynamic memory, leaving 6122 bytes for local variables. Maximum is 6144 bytes.
avrdude: WARNING: invalid value for unused bits in fuse "fuse5", should be set to 1 according to datasheet
This behaviour is deprecated and will result in an error in future version
You probably want to use 0xcd instead of 0xc9 (double check with your datasheet first).

Hi @nat2k. This warning is normal and expected. This warning is saying that the current configuration used to upload to the board works fine with this version of the AVRDUDE tool used to upload to your Uno WiFi Rev2, but that there are plans to stop supporting that style of configuration in some future version of AVRDUDE.

In the case of an Arduino boards platform, this is not of concern because the platform developers control which version of AVRDUDE is used. So they can simply update the configuration at the same time they update to the future version of AVRDUDE that requires it.

Arduino's developers are aware of the deprecation. In fact, they added this warning.

So forget about that warning and get back to having fun with your Uno WiFi Rev2!
