        Got the message below

Erase flash

Set boot flash true
CPU reset.

At this point Arduino never finds Com port and it disappears from device manager. Rebooted, reinstalled everything multilple times still the same result.
Davinci goes from 2 bars across to blinking on and off after flash and not recognized?
