Today I compiled the Meadow version 1.3.5.5 and when trying to deploy an app I got this error:

Meadow StdInfo: Mono will not start - version mismatch: Meadow.OS version 1.3.4.0, Mono version 1.3.5.5, Mono disabled
Meadow StdInfo: Mono is disabled
Meadow StdInfo: Mono has been enabled - restarting Meadow

This error was happening because I don’t have the version directory 1.3.5.5/ at “~/.local/share/WildernessLabs/Firmware/”. Let’s fix it:

$ cd ~/.local/share/WildernessLabs/Firmware
$ cp -a 1.3.4.0 1.3.5.5
$ cd ~/Meadow/nuttx/
$ cp Meadow.OS.* ~/.local/share/WildernessLabs/Firmware/1.3.5.5/

Now I can deploy the application correctly:

$ meadow app deploy -f bin/Debug/netstandard2.1/App.dll -s /dev/ttyACM0
