Nicla voice imu firrmware wont flash

Official Hardware Nicla Family Nicla Voice

Hi everyone!

I'm having trouble flashing the IMU firmware on my Nicla Voice board. The voice firmware works perfectly, but I can't seem to get the IMU firmware to work. Has anyone else encountered this issue, or does anyone have tips on successfully flashing the IMU firmware? Any help would be greatly appreciated!

Thanks in advance!

The firmware was successfully uploaded. The problem is that it does not work.

What has voice recognition to do with the IMU?

Have you found any examples on line of reproducible applications with this half-baked, largely unsupported Arduino product? If not, it is probably not worth your effort to pursue.
