Everloop LEDs do not turn on

After and update and upgrade (I am running buster now) my Matrix Creator works except that the Everloop LEDs don’t light up. None of them, any color. led.length returns 35 and no errors are thrown, but no LEDs turn on. Tried the C++ demos and Python, but no LEDs illuminate. Sensors and microphones all work fine.

What should I look at for debug or fix?

Thanks.

False alarm. I “upgraded” to a “low ripple” 3A power adapter. Turns out it must not be all that great as that was the problem. Matrix Creator needs better power filtering.
