        @vincent1 我现在已经勾选上a665042e-926b-4470-b346-0fdd0d2e8733-image.png
        并且在board.dts和uboot-board.dts中在disp中加上

        	disp_rotation_used       = <1>;
                degree0                  = <2>; 
        

        现在开机logo到kernel阶段时候已经旋转了180° 但是我的qt好像不能刷新屏幕了
        我用

         cat /dev/urandom > /dev/fb0
        

        lcd屏也不会出现花屏 请问接下来要怎么办???
