Hi there,
So the BSP is only compatable with certain LIBs, more than likely the One wire is Older and requires an older BSP. also I have an example code with compiler output as well , so you can see which versions worked for the Xmas Demo I have on here. I used the DS18B20 code is included. Gove Expansion board demo.

Roll back the BSP in the boards tab. Embed or non-embed BSP’s
in the compiler output you can see FQBN. version
