HDMI interface on DI1

Hello Community,

 

I'm involved in a project based on imx6Solo.

I would like to use LCD interface with DI0 and HDMI interface with DI1 of the IPU1.

 

In the file board-mx6q_sabresd.c I modifed hdmi_core_data.disp_id to 1 (it was 0 initially).

 

After booting the board over NFS

> setenv bootargs console=ttymxc2,115200 androidboot.console=ttymxc2 vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080@60,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M androidboot.hardware=freescale rw ip=dhcp root=/dev/nfs nfsroot=${serverip}:${nfsroot}

the monitor complains that the signal is out of range/not valid.

 

On the other side, if hdmi_core_data.disp_id is set to 0, I can see Android booting nicely on the HDMI monitor...

 

Analyzing the log file show that the clock ipu1_di_clk_1 is enabled. What else do I have to set up to deliver proper clock/data signals from DI1?

 

 

Any help would be appreciated!

Tomasz
