I am developing a Linux image on Colibri iMX7 with Aster Carrier Board. I am trying to display two different application on the touchscreen (Resistive Touch Display 7" Parallel) connected by DSI and on a screen connected by VGA. When a connected the VGA I get the same image that I have on the touchscreen. Moreover, I look in /dev for any second framebuffer, but there is only a fb0 which is used to display the image into both screens.
Someone knows how can I display different applications on 2 screens at the same time? Is it configured by u-boot?
