    In linux 3.0 based BSP, if we pass "no_console_blank=1" to the kernel parameters, then the console never goes into screen saver mode. 

    However this is not working in main stream based linux 4.4.76 The console blanks out after 10minutes and never comes back as there are no input devices in my system. What is the equivalent for preventing the console from blanking out.

    Thanks

    I am glad you got the LCD working. That's great news.


    You should be able to pass 'consoleblank=0' as a parameter and I would expect the screen to stay up. If you're using a newer U-Boot, you can type from U-Boot:

    nand unlock
    setenv optargs consoleblank=0
    savenenv

    if you want it to be less verbose during boot and boot a bit faster from U-Boot enter:

    nand unlock
    setenv optargs consoleblank=0 quiet
    savenenv
