Hi community,

 

I want to confirm about usage of i.MX6 HDMI & I2C.

I understand I can use common I2C for HDMI and I can use all I2C channel for HDMI (e.g. I2C1) if I don't use HDCP

But I should use DDC signal instead of common I2C if I use HDCP.

 

Then, I want to confirm whether I can use DDC signal and common I2C simultaneously.

 

I think I can use DDC signal for HDMI and I2C2 for other function (e.g. connection for PMIC) simultaneously as below because DDC signal is generated by HDMI module, not by common I2C module.

Is my understanding correct?

 

HDMI_TX_DDC_SDA -> EIM_D16 port (ALT4)

HDMI_TX_DDC_SCL -> EIM_EB2 (ALT4)

I2C2_SDA -> KEY_ROW3 (ALT4)

I2C2_SCL -> KEY_COL3 (ALT4)

 

 

Best Regards,

Satoshi Shimoda
