I am working on iMX6 solo based custom board.I am setting some PAD control values in my U-boot code but that values are not reflecting after U-boot boots up. So, I want to change the PAD control values after U-boot boot up , say suppose I want to set 0x1b0b0 to UART control PADS. How can I do that using u-boot coomand?
I know I have to use the mw command , but when I tried mw 20e0330 1b0b0 and then I tried reading at that address using md 20e0330 it didn't change the values to 1b0b0.
Kindly help me to solve this issue.
