S5PV210 android4.0 不支持480*272这种小分辨率的LCD显示？！ [复制链接]

一年前，android驱动工程师就在sate210 上调试过了android4.0 系统，当时他得出的结论是android4.0 不支持800*480以下的分辨率显示，如果LCD设置的分辨率这么小就会导致系统起不来加载异常，即使linux内核能起来，android也起不来的。后来我在一款MTK的山寨机上看到LCD 分辨率显示是640*480 也行的，以为他的观点是错误的，所以就在sate210 上试了480*272的分辨率，果然和sate210 android去工程师说的一样，是这么回事的吗，请做过的来说说看。
打印下面信息就死机了。
