I want to drive the 16x2 character LCD using GPIO pins 2 through 11.
Configured all those above GPIO pins are as outputs and generating signal to drive LCD. LCD is not displaying any text on it.
First, all these pins are not able to configured as GPIO pins because of ioremap() function fail in my dmesg output.
