Failed to Build Binary when using Custom Processing Block

Project: test_custom

I am using a custom processing and a custom learning block in this project. I can successfully train the custom model, using custom processing, and test it. However, when I try to perform live classification (audio) using my cellphone, or by launching in browser, I get the following error:

Note that if I use an Edge-Impulse-provided processing block (like MFE), keeping my custom learning block, then the issue doesn’t appear and I can successfully perform the live clasification.

Therefore, the issue only appears when I use my custom dsp processing block.

Hello @shossain,

Unfortunately, we cannot automatically generate optimized native code for the block.
