TFLite Micro - Target ESP32

[mono app]

Hello all,

I would like to run following example

https://www.survivingwithandroid.com/esp32-tensorflow-micro-speech-i2s-external-microphone/

based on current Tensorflow Lite github project.

I was able to find that the project was moved to a standalone one under:

https://github.com/tensorflow/tflite-micro

I see the project is tested for ESP32 devices, but I am not able to find ESP Makefile in the project. 

Could somebody please guide me here?

Thanks in advance.

Hi Mono, 

I am doing the same project using ESp-EYE platform. However, having trouble in compiling the program 

pls see below errors. Could you help me on this? Thanks in advance.

Hi all,

I see no portable_optimized directory under tensorflow/lite/micro/kernel. Is that something new?

I see the following directories, where testdata and test_data_generation are no optimized kernel dirs.

arc_mli/              cmsis_nn/             testdata/             vexriscv/            
ceva/                 ethos_u/              test_data_generation/ xtensa/

OPTIMIZED_KERNEL_DIR should point to one of these directories, for example OPTIMIZED_KERNEL_DIR=cmsis_nn.

Cheers,

Måns
