Can improper sequencing of the PicoZed SOM Vin, PWR_ENABLE and VCCIO_EN cause actual damage to the PicoZed Card?
In my application, I do not think I am handling the power-off sequencing correctly and Vin and power enable drop nearly coincidentally.
The PicoZeds that appear to be damaged do not seem to turn ON power LED D3 but the exact failure or root cause of why the 3.3V supply is not turning ON has not been determined.
Any additional guidance on power sequencing and the potential resultant failure of incorrect sequencing would be appreciated.
Thanks in advance for any input.
