This is the SECOND board i’ve received in a week and neither board will boot. No video output, no SD card activity, nothing. Just the red and blue light. And this is with power supplies ranging from 2A to 2.5A and 12 different cords. No change. Are these devices really this level of garbage that I can’t get a single one that actually WORKS?
Did you flash the MicroSD card properly with the right image? The state you described happens when the MicroSD card does not have the proper software.
