Hello. I have questions about EDID of HDMI TX, we met some problems.
i.MX6D (MCIMX6D6AVT10AD) chip is used.
Please refer to below hardware connection. Config of pins is as followed:
When we read EDID of HDMI sink device though HDMI_TX_DDC method, no signal is found on SCL & SDA.
1) On MCIMX6D6AVT10AD chip (on which HDCP encryption is disabled), can we use HDMI_TX_DDC method, rather than common I2C method, to read EDID of HDMI sink device?
2) If HDMI_TX_DDC method can be used, could you please help us to check how to solve the problem of no signal on SCL & SDA?
