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
