Linux: Jacinto dra7xx -Display framebuffer & overlay

Tool/software: Linux

Hi all,

  1. We do not find the overlay interface in our kernel 4.4 .

 http://processors.wiki.ti.com/index.php/DSS2_SYSFS_Examples.

 Is the following interface is supported ?

Setting framebuffer to overlay

Multiple overlays can be linked to a single framebuffer as shown in the example below.

  • Setting fb0 to overlay0:

echo 0 > /sys/class/graphics/fb0/overlays

  2. Once our complete system boots up and HMI is running ,we run the below command. we are getting our splash(initial bootlogo) screen. How is it happening  ? 

echo 3 > /sys/class/graphics/fb0/rotate

 

 3. Is  fb1  supported  ? Since only fb0 is available in /sys/class/graphics/ .

 

 

Regards

Gokul
