在RK3288上使用FireFly提供的标准7.85英寸eDP屏，无法启动Kernel

小明

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：

1. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ ls Image-rk3288_box
   
2. boot.img  kernel.img  misc.img  pcba_small_misc.img  pcba_whole_misc.img  recovery.img  resource.img  system.img
   
3. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di resource Image-rk3288_box/resource.img
   
4. Download resource start...
   
5. Download image ok.
   
6. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di -k Image-rk3288_box/kernel.img
   
7. Download kernel start...
   
8. Download image ok.
   
9. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di -b Image-rk3288_box/boot.img
   
10. Download boot start...
    
11. Download image ok.
    
12. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di -s Image-rk3288_box/system.img
    
13. Download system start...
    
14. Download image ok.
    
15. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di -m Image-rk3288_box/misc.img
    
16. Download misc start...
    
17. Download image ok.
    
18. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$ sudo ./upgrade_tool di -r Image-rk3288_box/recovery.img
    
19. Download recovery start...
    
20. Download image ok.
    
21. guoguo@guoguo:~/RK3399/Linux_Upgrade_Tool$

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。

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。

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。
