Hi community,

 

I have a question about i.MX6SDL HDMI.

Our partner is testing HDMI CEC fucntion with mxc_cec_test in L3.0.35_4.1.0 unit_test, but getting CEC version does not work well.

I saw hdmi mxc_cec_test.out function is not working, I think this issue is same as it, but it has not been resolved yet.

The environment of this issue is as below.

=====

[Board]

MCIMX6DL-SDP

 

[BSP]

L3.0.35_4.1.0

libCEC in L3.0.35_4.1.0

HDMI CEC is enabled

 

[HDMI Display]

TV which supports HDMI CEC or

HDMI analyzer

=====

 

Actually, our partner confirmed the CEC_TX_DATA value after write a value (0x409F) that is operation code to get CEC version.

Then, CEC_TX_DATA kept the value they wrote (0x409F) certainly.

However, actual output data was different.

Would you give me your comment why HDMI CEC cannot send the correct data to get CEC version?

 

 

Best Regards,
