@haverland @jomjol Can you confirm this?

[jomjol]

Yes, I can confirm the problem:

Strange, that it only happens with the 16.0.0 RC. With an older rolling (06/24) the tflite is working!

Did we update the tflite library in the background?

Short term solution: remove 0710 tflite and go back to 0700

[caco3]

Yes, I updated in on 28. Sept: #3220

I hoped that it would fix the issue but it still crashes without a way to catch it.

[caco3]

I can confirm that it is fine with the previous tflite library. I now reverted to that one. However it basically means, we can not update until we fix this issue!

[jomjol]

Looks, like there is a problem with the tflite since about 1 week:

https://github.com/espressif/esp-tflite-micro/tree/master

Let's keep this open, to follow updates of tflite-micro

Ok, but I remove the release 16.0.0 tag
