Linux/AM3352: GPMC Nand flash Wpn

Rohit Khatri

Part Number: AM3352

Tool/software: Linux

We have many products with AM3352 and using 256MiB Nand flash.

Till the time in all designs, GPMC WPn line has pull up resistor and from pin muxing it was in Mode 7 means in GPIO.

How GPMC controller is utilising this pin and how during read and write operation on mtd, this pin is being used?
