求教!
请用官方的固件试一下

我需要在源码上增加需求,下载下来的源码 就是点不亮 edp 屏,官方固件可行
感觉是 dts文件 配置不对,能贴个 dts 文件 吗 jpchen 发表于 2017-9-26 16:30

你的帖子 我有看过,我用的是 Firefly-RK3288-Reload ,也是按照步骤 做下来的, 中间有个步骤 没从 bitbucket 处更新 源码,我用的源码是这个版本的firefly-rk3288_android5.1_git_20170224.tar 已解决,修改了 rockchip,disp-policy = <DISPLAY_POLICY_SDK>;
&fb {
rockchip,disp-mode = <DUAL>;
rockchip,uboot-logo-on = <0>;
rockchip,disp-policy = <DISPLAY_POLICY_SDK>;
};
但是 rockchip,uboot-logo-on = <1>; 这个值为 1 时,还是会黑屏,这个应该是uboot logo 的开关吧
有哪位大神知道的,还请指点下 小默jiang 发表于 2017-9-27 14:05
已解决,修改了 rockchip,disp-policy = ;
&fb {
rockchip,disp-mode = ;
我的只有rockchip,uboot-logo-on = <1>时才能亮
