ESP32 Forum

My current SW compiles o.k. but during startup of the µC I receive strange messages (in yellow):

0x40080000: _WindowOverflow4 at E:/msys32/opt/esp/esp-idf/components/freertos/xtensa_vectors.S:1685

and

0x400d0018: _flash_cache_start at ??:?

and

0x4008bfa4: bb_init at ??:?

Do I need to worry about these messages?

No, no need to worry. Those are from the ``make monitor`` command. As soon as this sees a hex number scroll by that smells like an address in the ESP32 memory map, it tries to be helpful and converts it to a symbol. In some cases, this leads it to weird messages like this.
