Linux/AM5728: AM5728 support two channel 1080p60 display.

Part Number: AM5728
Other Parts Discussed in Thread: DS90C387

Tool/software: Linux

Hi Team,

My customer want to ask whether our Processor SDK Linux could support two channel 1080p60 display for the AM5728, because they want to use two isolated display screens to show different contents, each of which needs to be 1080p60. Can this requirement be meet in our Processor SDK Linux? 

In addition, is the color pin function configurable to make the 6 bit display compatible with 8 bit?

This is because the AM5728 is using D0-D17 for 6 bit mode, while D0-D23 for 8 bit mode. Customer want to made a hardware compatible design to support both design, so they can made a compatible design support DS90C387 dual channel LVDS.

    Yes, this is possible. AM5728 IDK EVM demonstrates dual display - one HDMI @ 1080p60 and other 1920x1200 LCD display @ 60 fps

    No. You can always use 24bpp mode in DSS, and if the panel only wants 18bpp, then leave the lowest 2 pins of each channel disconnected.

    VOUT_18bpp[17:0] = {VOUT_24bpp[23:18], VOUT_24bpp[15:10], VOUT_24bpp[7:2]}
