The problem is when I use ESP32-LyraT-V4.3 to run the example project play_mp3 in ESP-ADF，the ESP32 keep rst and the log is：

Hi @jiang123

Could you please help setup gdb debug: http://esp-idf.readthedocs.io/en/latest ... nitor.html

When the reset occurs, it will jump to gdb, then type bt and copy full backtrace information to here

Thanks

[jiang123]

Thanks for you reply!After I setup gdb debug,the log is :
