How IMX7D uses / dev / fb1
Hello everyone,
  My development board is the IMX7DSABRE board provided by the official website, the operating system version is Linux-4.9.88
  During use, our monitor can already display normally, we want to use the function FB_MXC_OVERLAY. At present, we already have the device node / dev / fb1, but this node corresponds to the video stream. How can I display the corresponding video on my screen?
