Tool/software: Linux
I want to run the example application dual-camera_demo on AM437x Starter Kit. But it failed, because it couldn't open the device /dev/drm. Then I checked the directory /dev and didn't found the device file. I didn't do any customization for the Linux kernel but used the zImage provided by TI's package. I found the following device files:
/dev/fb /dev/fb0 /dev/dri/card0 /dev/dri/controlD64
I think the DRM driver for display was running well. How can I fix this issue? Modify the dual-camera application? Or re-configure the Linux kernel?
