I’m using a custom board based on an Artemis module by Sparkfun.
I built a small model using Edge Impulse and uploaded it using arduino IDE.
It seems like Artemis freezes - doesn’t communicate over UART or shows any life signals.
This happenes ONLY when flashing the ei library (without even calling its functions!)
I recommend adding some print and sleep statements during the boot sequence to see if you can get anything to print and to figure out where in the code the program is hanging. My guess is that you’re running out of RAM and not seeing the “TF Arena” error message.
We don’t have much experience with the Artemis, but a few users have had some success. In addition to finding out where the program is failing, I recommend checking out these threads:
