Description

I tried to build he sketch below with the latest 2.0.15 core (not manually installed, but via the board manager of the Arduino IDE). It will not build because with the latest core it runs out of DRAM. With core version 2.0.14 it builds fine without any problems.

It seems that with every new version of the ESP32 core more and more memory is used. I ask myself what for? I did not change anything in my sketch, but the core etas more and more DRAM.

Would it be possible to give the ability to enable/disable some core functions in the board parameters to get rid of those RAM hogs?

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

Example builds again by optimizing the used audio libs. Nevertheless, increasing memory consumption of the ESP32 core is really annoying....
