在RK3288上使用FireFly提供的标准7.85英寸eDP屏，无法启动Kernel
打算在FireFly RK3288上点亮eDP屏，从商城购买了一块Firefly官方支持的7.85寸eDP屏。打算先点亮这块屏，然后作为参考再点亮其它eDP屏。现在把代码更新到最新后，然后打上这块屏对应的patch。打完patch后，生成的diff文件如附件。编译出新的Image后，然后烧入RK3288。烧写时使用的命令如下：
guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ ls Image-rk3288_box

烧写成功后，启动时发现无法启动到Kernel。出现的画面如下图。

你怎么把显示策略改了，按着补丁的来就行 标记一下，马上就要开始调试panel了。 Livvol 发表于 2017-1-3 17:33

补丁上也是改变了这个策略。
我还是先按照你说的试一下吧。 本帖最后由 小明 于 2017-1-4 10:09 编辑
我的问题已经搞定，感谢各位帮忙。
我是同步到最新代码之后，然后重新编译，烧录自己编译的镜像，启动时出现这个问题。
有位大神告诉我可能是misc除了问题。
解决步骤是：
1.找到Firefly发布的最新的update.img;
2.在RK3288上烧写这个update.img
3.开机启动正常。
4.烧写自己的编译的imgs文件，除了misc.img。
5.开机正常启动。
