I tried to deploy multiple impulses on the Nano 33 BLE sense and I get the same error every time. I have also used Platform IO in one instance to see if it would work like that. Both times I get the same error.
Starting inferencing in 2 seconds…
ERR: Would write outside feature buffer

I tried to increase the EI_CLASSIFIER_NN_INPUT_FRAME_SIZE but with no result. I think the problem is somewhere else.
There are 2 processing blocks in your design. But only 1 of them is connected to the learning blocks. Still both of the blocks are being deployed. This results in the feature buffer being too small. We will add a check in our code to prevent adding unused processing blocks.
For now you can simply remove the Spectrogram block.This should fix the issue.
