Seems like an easy fix

[kevin-pololu]

We're having trouble reproducing your issue. What OS and Arduino version are you using, and what program are you trying to compile?

Note that those warnings are coming from some support files that were originally needed because the Arduino toolchain didn't support the ATmega328PB, but they are now unnecessary and we are looking at removing them, so this might become irrelevant soon anyway.

[triffid]

I just followed https://www.pololu.com/docs/0J74/4.3 in Arduino 1.8.19 and gave the Blink example a test compile.

Running on Gentoo Linux with Arduino configured to use my system avr-gcc (12.1.0)

[DavidEGrayson]

We just released version 5.0.0 of the A-Star boards package. If you update to the latest version using the Arduino IDE's Board Manager, these warnings should go away because the file generating them has been removed.

[triffid]

Board manager only shows 4.0.2 and older versions, do I have to do something special to see the latest one?

Oh, looks like your domain is having DNS issues, that'll do it

[triffid]

Working now, warnings are gone with 5.0.0 👍
