Hi 

 

We define EIM_OE and EIM_D29 as a GPIO to drive enable pin of LCD Driver IC which is having power sequencing. 

But before reaching my code till uboot, these pins are get toggled by default and its violate the power sequence.

 

Please let us know who is driving the GPIO beofre my code reach at those lines in uboot. After uboot we ae getting same sequence which i defined in my code. but beofre that someone is toggling those pins.

 

Thanks

Sagar
