MCIMX6Q4AVT10AD HDMI not working

Hi all,


HDMI not working on my custom board based on MCIMX6Q4AVT10AD.


Register reading:

HDMI_DESIGN_ID:0x00120000 =  0x00

HDMI_REVISION_ID:0x00120001 =  0x00

HDMI_PRODUCT_ID0:0x00120002 = 0x00


MCIMX6Q4AVT10AD not have VPU. Does not HDMI also?!


The identical assembly of LINUX works fine on the board with the MCIMX6Q5EYM10AC processor.



1) If the CPU does not have a VPU, then there is no HDMI?

2) If the MCIMX6Q4AVT10AD has HDMI, why is HDMI_DESIGN_ID read as 0?

3) Is there any difference in the turning on of HDMI for processors with and without VPU?




Best regards,
