Dear all,
When I operate i.MX53 stand-alone -- only with LCD via touch-screen, have only power supply connected and no other peripherals attached, -- boards suffers from poor grounding, by exposing hectic USER1+2 button activity:
Whenever I touch any of those buttons (no press-action involved), it starts sending pressed events at an extremely fast rate (potentially halting the running OS).
Whenever I attach a well-grounded cable (USB/µUSB, serial, VGA), this behaviour goes away.
The board is intended to be used as stand-alone, without any wires supplied and no possibility to ground it - how could the button behaviour be fixed? Soldering a capacitor did not help (it then nearly completely disabled buttons sending any action when pressed)
Many thanks,
Simonas
