Self learning classifier not working in Maixduino


I’m following the instructions here:

I flashed the latest firmware “maixpy_v0.6.2_27_g4d8d4fbf0.bin”
I downloaded the model “sipeed_learn_model_232ec562d737fdf3f64745d32dd7ebfc.smodel” on address 0x300000

When I connect to the board using MaixPy IDE and run the demo script “” nothing happens.

Any idea what could be wrong?

I’m on a Maixduino
