imx6 android6系统  uboot配置为mipi_dsi显示,配置参数为setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=mipi_dsi,TRULY-WVGA,if=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=320M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M androidboot.selinux=disabled androidboot.dm_verity=disabled no_console_suspend
        把kernel-imx/arch/arm/boot/dts/imx6qdl-sabresd.dtsi 做修改
       mxcfb1: fb@0 {
                compatible = "fsl,mxc_sdc_fb";
                disp_dev = "mipi_dsi";
                interface_pix_fmt = "RGB24";
                default_bpp = <24>;
                int_clk = <0>;
                late_init = <0>;
                status = "disabled";
        };
一进入系统就卡住

boot命令换成lcd显示 则正常进入系统,这是什么原因?
