hi ,
everyone
who can give me a example which set the gpio pin go high or low in uboot.
We designed a board using DM8168，but we read most gpio registers is 0x0.such as :
gpio vertion=0x206435
gpio 0x48033010=0x0
gpio 0x48033020=0x200
gpio 0x48033024=0x0
gpio 0x48033028=0x0
gpio 0x4803302c=0x0
gpio 0x48033030=0x0
gpio 0x48033034=0x0
gpio 0x48033038=0x0
Thanks!
