i'm trying to enable on a IMX6Q Sabre Lite two screens with two different contents. My software is bare metal and run just after U-Boot.
Running U-Boot phase, i'm have the two screens (LVDS and HDMI) in mirror configuration (both are have same content).
Then in my software i configured the system to have
- LVDS screen on IPU1 DI0 using IDMAC channel 23 (DMFC channel 5B DC Channel 5) on display 0
- HDMI screen on IPU1 DI1 using IDMAC channel 24 (DMFC channel 6B DC Channel 6) on display 1
the LVDS is OK but the HDMI is not. I have "no signal" on my screen. Would it be possible to get all the registers to have the HDMI working (clks, Mux ...) ?
Any help would be very welcomed as i followed as much as possible all the doc and was not able to find the issue.
Thanks in advance for your help.
