Linker error when compiling newest firmware (Ubuntu MATE 22.04 LTS, Kernel 5.15 x86_64)

[europa64]

I've been working on getting the newest firmware compiled, and I've run into a linker error.

Here's my uname string: Linux 5.15.0-78-generic #85-Ubuntu SMP Fri Jul 7 15:25:09 UTC 2023 x86_64 GNU/Linux

and here's the error itself:

thanks for the report! i can reproduce this on nixos with a fresh ~/.platformio and .pio:

it looks like this is maxgerhardt/platform-raspberrypi#79 (and several others), caused by me pinning the framework version but failing to pin the platform version. i’ll pin the platform to a compatible version.
