I agree, sounds like HEAC (HDMI Ethernet/Audio Return Channel) won't work as we don't have the pair connected to the CPU and that signal is HEC -- differential, ARC -- single-ended. On the other hand HPD (Hot-Plug Detect) should work. > CEC does seem to be routed and is mentioned on the A20 info page. > > No SBC that I've seen actually uses these functions (unfortunately). We'll have to see if we can make it work. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
