Can't upload firmware to the Arduino Uno WiFi rev.2

[LumitoLuma]

Bug Report

Current behavior

I've tried to upload the NINA firmware (1.4.6) to my Arduino Uno WiFi rev2. When it gets to the INFO[0008] Opened port /dev/ttyACM0 at 115200 line, the board resets and sends an RX command to the Uno WiFi rev.2 as expected, but then it gets stuck. I have tried it about ten times and I've also disconnected and reconnected the board, but without success.

I've run the following command:

./FirmwareUploader firmware flash -v -b arduino:megaavr:uno2018 -a /dev/ttyACM0

Expected behavior

The firmware should upgrade without problems.

Environment

• Updater version: Git, commit d4c7b34
• OS and platform: Debian Testing x86_64, Linux 5.10.40

Additional context

I also had a similar problem with previous (stable) releases of the tool: When it tries to connect to the programmer (Uno WiFi rev.2) to start uploading the firmware, the upload fails unless it gets an immediate response from the board.
