saLoopBack

Just a suggestion:

I get this when my camera source is turned off. Otherwise I get mode is set to 720p. 

Also in the example, memory map from one of the fb display devices buffer is used to do video capture. I had to modify that call to set the size requested explictly to 720*1280*2 per buffer, to a total of 8 buffers.

Otherwise, there is tearing in the output video.

Your issue is also covered here: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/154472.aspx#559655

There are two HDVPSS  firmwares in the EZSDK 3.01( http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html), to switch between them use the following instructions (from another e2e post):

 $ cp /usr/share/ti/ti-media-controller-utils/load-hd-v4l2-firmware.sh /etc/init.d/load-hd-firmware.sh

$ sync

 Now power cycle your board.

 To revert your changes back to use the default firmware which supports OMX Capture please run the following command

 $ cp /usr/share/ti/ti-media-controller-utils/load-hd-firmware.sh /etc/init.d/load-hd-firmware.sh

$ sync

 Now power cycle your board.

Hi,

This happens when VIP is not able to detect the source. You can check following things.

1. Try reconnecting daughter card to base board. This may be one issue. We have seen this.

2. Make sure that Y, Pb and Pr are connected properly.

Is this the first time you are trying capture or did it work for PSP13_patch2

Regards,

Hardik Shah

Hello,

Thank you for your response.

1) I disconnected and reconected the daughter card.

2) We checked the video signal with 'scope all the way to the IC. And have double checked Y, PB and Pr.

3) This is the first time we have attempted this.

Do you see anything in our steps that we are doing incorrectly?

Thank you,

Chris 

Apparently DVD players will not supply 1080p (or 720p) on the component outputs due to copyright/encryption etc.

We will assume then that our setup is correct and find an appropriate 1080p/720p source.

Thank you.

Hi,

I am not sure why are you not able to get this up. But if you are suspecting the DVD player, You can modify any of the V4L2 display application to throw display on component output of DM816x. Connect component output of DM8168 to component input. This way you will be sure that source is not a problem.

Thank you. Okay I am now sure of the source. I am using an XBOX 360 with a "HD AV cable" hooked up to the component inputs.

With the XBOX set to 720p and 1080i I got no output but when set to 1080P I get this crash dump (and no video out).

Update:

I see that the same issue "spinlock_irq_save" is addressed in this thread:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/154472.aspx?PageIndex=2

After the prompt returns, I run saLoopback again without getting the warnings however I still do not het on video out on the LCD connected to the EVM's HDMI output.

We got it. We needed to load the HDMI module.

insmod ti81xxhdmi.ko

Thank you for your support.

Hi,

Crash dump is a know issue. Further PS3 will be able to give 1080I60 and 720P60. You have to configure it using settings-->display settings menu under PS3. We have tested both modes.
