        配置G2D旋转,内核勾选G2D旋转,配置G2D驱动,DE设备树增加rotate字段

            在 board.dts uboot-board.dts中加上

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

            后开机logo在kernel阶段后确实旋转了180° ,但是我的fb0设备好像不能被调用了,不能显示东西了 只停留在logo界面 我用

            cat /dev/urandom > /dev/fb0
            

            也没有反应
