When i debug to the point where it fails i have added a picture. Why is current 0xFFFFFFFF?

i have tried it now also with the esp32s2 kaluga -1 v1.3. With this dev board it is working. It seems i have an issue by adding a custom audio board. What is the prefered way to create a custom audio audio board.

When i switch to the my board with a ES8388 as audio ic and the ESP32-S2-WROVER i have the issue. It is strange what could cause to such a behaviour.

thanks michael

Hi MSD-Systems

This phenomenon can not accurately judge the problem, but there are some lessons to share with you. This seems to be a memory problem, it is recommended to check the code first, you can turn on the IDF heap debug function.
