Hi All,
I want to know wht's going on inside the i.MX 6Q when i connect HDMI output to HDTV's HDMI input ?
From basics of HDMI initialization sequence:
H/W should follow this steps:
1-> HPD detection.
2-> EDID read
3-> send 30 unencrypted Video frames
4-> start HDCP authentication.
Is it the right sequence i.MX 6Q HDMI Tx follow ?
What happen in case EDID is not valid ?
How HDMI Tx send 30 video frames ?
How HDCP authentication initiated by i.MX 6Q ?
Reason to ask, as i stuck on step-3 above.
When i connect HDMI cable on i.MX 6Q , i receive Hot Plug Detection event & my SABRE-SD board's Android source code read EDID from I2CM bank.
It means, i.MX 6Q HDMI Tx had read EDID successfully but i don't know wht next step HDMI Tx shuold OR will be follow ?
Can anybody answer this question ?

Hi Daiane,
Thank you for your information.

As I know the default imx6 board does not support HDCP (at least without hardware rework)
Are you using a custom board?
Hi Daiane,
Thank you for your reply.
I have MCIMX6Q -SDB board. Other tag on board are: "SCH-27516 Rev C1" & "700-27516 Rev A".
Is hardware rework required for this board? If yes, can you please tell us how to do that ?
