816x Expansion I/O daughtercard: Which Inputs are supported by SDK?

OK - can I use component capture on TVP7002 #2, though? I was kind of hoping I could test with two channels somehow.

OK, thanks.

Hi,

I'm reviewing XIO schematic rev.C. It has TVP5147 for component, and S-video input and interfaced with 16-bit pixel bus and clock output.

It seems to use embedded sync. I've checked the TVP5147 manual and noticed it looks like supporting only 8 bits embedded sync. I'm wondering

if it support 16-bits embedded sync or not ?

Regards,

Sympson

Hi,

TVP5147 does not support 16 bit interface in embedded sync interface. You will have to use 16 bit discrete sync interface.

Thx,

Also having trouble getting the various video inputs on the expansion i/o daughter card to work. In fact, even the McFW demo app is not able to 'detect' any video sources. 

Setup ... I've re-targeted the ‘DVRRDK_V03.00.00.00’ at the EVM (using Rules.Make) and can boot (kernel), load the M3 firmware and A8 ko’s and even run the mcfw cmd-line demo (/opt/dvr_rdk/ti816x/bin/dvr_rdk_demo_mcfw_api.out) that works on the DVR-RDK board.

Output on the command line seems to indicate that everything (M3fw, ko, program) loaded and is running correctly, and the monitor connected to the HDMI-out (not the daughter card) display shows the “Texas Instruments” overlay (i.e. the OSD generated by the C6x DSP) but I can’t seem to access any video inputs that I have connected to D12 (composite input via NTSC camera), HDMI IN2 (DVI video via DVI camera) or [D6, D7, D8] (component in via another 8168x_evm board demo).

I would assume that I would need to modify a driver of some sort to gain access or 'map' to the correct video inputs (on the EVM). Perhaps someone here can help? Ideally, we are looking at getting the 1xDVI (HDMI_IN2 on the EVM) and 1xNTSC_composite (D12 on the EVM) video inputs working.

Hi,

Component input is supported with 1080P60, 720P60 and 1080i60 modes.

Hello HardikShah,

I am working on DM816x-EVM(Netra) based custom board.

Custom board setup is as following:

We have DM816x Video ports connected to FPGA logic. At video RX side FPGA will recieve video from HD-SDI and converts it to 1080p30/1080p25/720p50 format and feed to VIN0 (x16) of DM816x. At video Tx side DM816x will feed VOUT1 (x16) 1080p30/1080p25/720p50 format to FPGA where it converts to HD-SDI and sent for display devices.

Note : 1080p30/1080p25/720p50 format are user configurable at DM816x as well as at FPGA.

Following test cases are passed:

 For all 1080p30/1080p25/720p50 formats, Omx Capture_encode application & saLoopback application works fine with custom board.

But end user application needs GST pipelines.

Following is the issues i am facing with gstreamer applications.

1) For 1080p30: Works fine

Hope you understand my problem, Please help in this regard. to make gst pipelines works for 1080p25 & 720p50 formats.

Thanks in advance
