标题: 按照论坛上的方法，7.85寸屏不亮
根据论坛上给的Android5.1的补丁，打补丁和编译都没有报错，但是屏不亮

根据http://wiki.t-firefly.com/index. ... F.E6.A8.A1.E7.BB.84的方法

官方固件可以亮吗
可以的话把修改的全部发出来看

官方固件可以

rockchip,disp-policy没改到，还有uboot有没有更新

作者: lzh 时间: 2016-5-22 00:00
我也是按照那个方法，没点亮。

点亮了，原来有个地方理解错了。如下：
&lcdc0 {
      status = "okay";
      rockchip,iommu-enabled = <1>;
      rockchip,prop = <PRMRY>;
      power_ctr: power_ctr {
         rockchip,debug = <1>;

         lcd_en:lcd_en {

            gpios = <&gpio0 GPIO_B5 GPIO_ACTIVE_HIGH>;
            rockchip,delay = <10>;
         };

Uboot的编译要用make rk3288_config 不能用make rk3288_box_config。
