Thanks for your reply. That's what I was wondering... I was hoping maybe it did and just was not advertised.

I suppose this file:
https://github.com/tensorflow/tensorflo ... a_hifimini

requires different hardware than the standard ESP32.

I see the Tensorflow-Micro project now supports the ESP32:
https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/micro/kernels/xtensa_hifimini

Does anyone know how to build for this target?

Specifically, I'm looking for the header:
#include <xtensa/tie/xt_hifi2.h>

Any insights ...
