Program BHI260AP directly on the Nicla Sense ME

[Ismar]

Hello Everyone,

I am working on a project where I want to use the IMU and other sensors of the BHI260AP to train a tensorflow lite model in order to do some classification. I got some tensorflow lite models working on the Nicla, with the integrated NRF52 MCU, but the RAM (64 KB) limits me from implementing any larger models.

I can see that the ARC MCU on the BHI260AP has 4 times as much RAM, but I haven't figured out how to directly reprogram it. From googling I have seen that these types of MCUs generally support tensorflow lite, but is there a way to get acces to that MCU and program it, so I can maybe create another sensor output, which just does the classification I want, just like the step counter?

It would be really great if I can use the BHI260AP to do all the ML stuff on it, and then only use the NRF for the application side of the project.

Thanks in advance!
