Error when try to upload the WiFi 101 Firmware Updater

I'm using Arduino UNO and the library WiFi 101.

Simply when I try to upload the Firmware Updater sketch from File -> Examples -> WiFi101 -> Firmware Updater I get this error:

Arduino: 1.8.12 (Linux), Board: "Arduino Uno"

data section exceeds available space in boardSketch uses 9908 bytes (30%) of program storage space. Maximm is 32256 bytes.

Global variables use 2145 bytes (104%) of dynamic memory, leaving -97 bytes for local variables. Maximum is 2048 bytes.

Not enough memory; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing your footprint.

Error compiling for board Arduino Uno.

This report would have more information with

"Show verbose output during compilation"

option enabled in File -> Preferences.

  • The problem is clear which is this sketch needs more than the available memory in Arduino. But how can I solve that?

Thanks

The message says that you are trying to compile for an UNO. Did you select the right board in the tools menu? – Delta_G
@Delta_G, WiFi101 shield is for Uno too – Juraj
Ok, wasn't sure. Never used the WiFi101. Didn't know if it had a separate board entry. – Delta_G

In the FirmwareUpdate sketch change static const int MAX_PAYLOAD_SIZE = 1024; to a smaller size. Try 256.

The program you try to load onto the board is for Arduino MKR1000 and UNO pin compatible boards with larger memory, if you want to update the firmware of a wifi101 shield attached to an UNO use the extension in 

Tools -> WiFi101 / WiFININA Firmware Updater

If you need to install this here are the instructions

  • Download the tool from this page.
  • Create a tools folder in your sketchbook, if it doesn't exist yet.
  • Unpack the zip archive into tools folder (it will look like .../Arduino/tools/WiFi101/tool/WiFi101.jar)
  • Restart the Arduino IDE.

And this programm finds the current version of the firmware
