I wrote a tiny4412 LCD equipment platform, want to verify the right, but have a problem,
My intention is to get rid of the kernel LCD platform device, the kernel boot LCD is not so bright, then I start the development board to enter the root file system, insmod my lcd_device. Ko, so you can make the LCD light, (at the time of uboot to the kernel, the uboot bootargs has cancelled transfer LCD=S70), but I the kernel boot, LCD will light up, or show four penguins? What reason be?
kernel commented out own platform device

CodePudding user response:

1. Empty the kernel recompiling.
2. The power of the screen is what? Are you comment that?

CodePudding user response:

If I comment out the kernel is not platform equipment? Only platform kernel driver without platform equipment, LCD can light up? This is what I want, I feel that my problem has been clear enough,

CodePudding user response:

I told you about, he had written a LCD driver, want to put the Tiny built-in LCD driver uninstall, insmod write their own, but don't know where can uninstall with this LCD

I told you about, he had written a LCD driver, want to put the Tiny built-in LCD driver uninstall, insmod himself wrote, but I don't know where can uninstall bring the LCD

Brothers, solve later told me how ah? Although I don't do this now,
