i.MX6 HDMI register setting for blank area.

[satoshishimoda]

Hi community,

Our partner have a question about i.MX6 HDMI.

They want to confirm the register setting about HDMI.

Please see HDMI_FC_INHBLANKx and HDMI_FC_INVBLANKx registers in IMX6DQRM (Rev.3).

They think this setting value should be (front porch + back porch [pixels or lines]).

Is this correct?

Best Regards,

Satoshi Shimoda

Hello,

The frame consists of active + blank periods for horizontal and vertical scans.

Have a great day,

Dear Yuri,

> The frame consists of active + blank periods for horizontal and vertical scans.

Yes, so we think HDMI_FC_INHBLANKx and HDMI_FC_INVBLANKx should be set to blank period (front porch + back porch [pixels or lines]), right?

Hello,

generally :
blank period = front porch + back porch + sync
