ERROR:drm_init_device:755: could not open drm device: No such file or directory (2) sh: line 1: 1792 Segmentation fault DISPLAY=':0.0' /home/root//dual_camera-new -qws
运行时爆出了如上的错误，前面设备的配置代码如下：
/*

void default_parameters(void)
{

memset(&drm_device, 0, sizeof(drm_device));
strcpy(drm_device.dev_name,"/dev/drm");
strcpy(drm_device.name,"drm");
drm_device.width=0;
drm_device.height=0;
drm_device.bo_flags = OMAP_BO_SCANOUT;
drm_device.fd = 0;

strcpy(cap0_device.dev_name,"/dev/video1");
strcpy(cap0_device.name,"Capture 0");

}
if (drm_init_plane_zorder(device))

}求TI大神指点迷津！！！
