我们板子参照sabresd设计的。之前使用系统android4.2.2，现在移植官网BSP android4.4.3 目前surfaceflinger导致系统启动失败。一直打印如下红色显示的信息。 request_suspend_state: wakeup (3->0) at 7437213333 (1970-01-01 00:00:04.592911333 UTC) 130|root@sabresd_6dq:/ # request_suspend_state: wakeup (0->0) at 956991823113 (1970-01-01 00:15:54.147520447 UTC) init: untracked pid 6193 exited request_suspend_state: wakeup (0->0) at 961401889447 (1970-01-01 00:15:58.557587114 UTC) init: untracked pid 6221 exited uboot环境变量设置setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,bpp=32 video=mxcfb1:dev=off video=mxcfb2ff video=mxcfb3ff vmalloc=400M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M androidboot.serialno=110ea1d4df646307 Logcat中： I/SurfaceFlinger( 119): SurfaceFlinger is starting I/SurfaceFlinger( 119): SurfaceFlinger's main thread ready to run.
