Re: Blackscreen on CVBS output

Hi lleri, No problem! You can play media on the CVBS output using the "Aux-GDP2" plane.

Re: USB sound card

Hello bfontaine,

Can you share the device's VID and PID? lsusb should be able to tell you this information.
Do you see anything related in dmesg or while booting?
Do you know if the device is supported on Linux? can you try it with a Linux PC?

Re: RX calibration fail

Hi vsavu, Thanks for the extra information. Unfortunately I don't have a rev B board to hand, but there shouldn't be any difference on the USB 3.0 interface. I've just tried the following devices using a rev A board and they worked fine. 1d6b:0003 - Anker USB 3.0 hub 0b95:1790 - ASIX 88179 Gigabit E...

Re: USB SSD enclosure killed the board?

Thanks Dan,

I suspect these signals are inverted by the peripheral configuration, though it's certainly worth confirming this.

We'll contact you directly via email to discuss further.

Re: HDMI Input to Output with color keying

Hi irisg_guy, Yes, this is indeed possible. We currently use this technique with our port of the Parole media player to effectively " poke a hole " in the UI / desktop for the video to appear through. We've settled on #080810 as the " transparent " color - so anywhere this appears will actually let ...
