Hello, I intend to use TX1 to implement HDMI-CEC function, and could you show me where is the code(about CEC interfaces) ?Thank you!

Hi nklc2009, I cannot guarantee that, since L4T only has this part related to CEC. Tegra has once made some work in HAL, but that is not on L4T and I cannot access to it, either.

Thank you!
Does that mean we can not use HDMI-CEC now on TX1? But in this document, Tegra_X1_TRM_DP07225001_v1.2p.pdf, TX1 can support HDMI-CEC.
