800*600分辨率导致系统无法开机 求解决
版本 V1.2系统 andriod4.2.2
内核 linux3.3
在config.fex配置1024*768能显示正常，但800*600配置上去就出现错误了，我提供部分logcat和dmesg，求解决。

请问你是怎么改的sys_confg.fex,贴出来，另外，你的显示器是多大的，你默认是什么输出,Vga还是Hdmi? chuang 发表于 2014-6-17 22:02 static/image/common/back.gif
请问你是怎么改的sys_confg.fex,贴出来，另外，你的显示器是多大的，你默认是什么输出,Vga还是Hdmi? ...
sys_config.fex配置没问题，显示器是12寸的 最大分辨率支持800*600， 接口是VGA或者Lvds
都试过，不行，是驱动的原因吧？
可以先不要改sys_config.fex,在设置-》显示-》显示输出模式，可设置显示输出的分辨率,试试能不能显示正常！若显示不正常，就是源码驱动不支持了 lichee\linux-3.3\drivers\video\sun7i\disp\dev_fb.c
的问题，更新下
