Prevention of the device from booting
Irreversible damage to the i.MX53xA processor (worst-case scenario)
• The consequent steps in power up sequence should not start before the previous step supplies
shows the USB interface current consumption.
Power Supplies Requirements and Restrictions
have been stabilized within 90-110% of their nominal voltage, unless stated otherwise.
