A happy new year everyone!
I do have a Waveshare epaper display application which was running flawlessly for over a year. All ESPhome updates over the past could be installed w/o problems. Now I wanted to update the ESP32 to version 2025.12.4 by using the “Update” button in the ESPhome dashboard and I am getting to following compile error:

WARNING GPIO15 is a strapping PIN and should only be used for I/O with care.
Attaching external pullup/down resistors to strapping pins can cause unexpected failures.

There were no code changes on my end, and no changes to the waveshare_213v3.ccp code (at least that I am aware of)
I am runnung homeassistant Core2025.12.5; Supervisor2025.12.3; Operating System16.3; Frontend20251203.3, ESPhome
Any idea anyone what could be wrong here?
Thanks Stephan
