encode demo on custom DM368 board

Hi Hongfeng,

Can you try running the application with DMAI_DEBUG=2:

DMAI_DEBUG=2 ./encode -I 4 -v test.264 -t 5 -w

This should give you some trace output that would help with your debugging. My guess is that the capture thread (see captureThrFxn() in dvsdk-demos_4_02_00_01/dm365/encode/capture.c) is stuck either in initialization (i.e. Capture_create) of the video driver or waiting for video data to come in (i.e. Capture_get). You may also want to insert your own debug "printf" calls throughout the thread to better isolate the issue.

Best regards,

Vincent

Thanks for the reply, Vincent.

I tried your suggestion, it appears to be stuck at catpure_get() function. How do I dig deeper into this?

I found there is no interrupts from  vpfe_capture0. IRQK_handler didn't even show up.

The waveforms of HD,VD and PCLK are almost identical to those on EVM.

The pinmux should be set properly in dm365_ccdc.c.

Am I missing some simple stuff?

Hi,

One simple thing that can cause the interrupts not asserting is that you might have set the VDINT0 register value to be higher than the number of input lines in the frame. Please check the value of that register and compare it against the input frame height. VDINT0 should be set to (frame height - 32) approx.

Regards,

Anshuman

PS: Please mark this post as verified, if you think it has answered your question. Thanks.

Anshuman:

Thank you so much for your help.

Now I have found something interesting:

I inserted these two lines at the end of function ccdc_setwin()

    dev_dbg(dev, "vert_nr_lines=%d",vert_nr_lines);
    dev_dbg(dev, "VDINT0=%d",regr(VDINT0));
    dev_dbg(dev, "VDINT1=%d",regr(VDINT1));

And I found the output are:

vpfe-capture vpfe-capture: vert_nr_lines=719
vpfe-capture vpfe-capture: VDINT0=0
vpfe-capture vpfe-capture: VDINT1=0

Obviously the VDINT0 was just set by this code: regw(vert_nr_lines, VDINT0);

Why?

Two more questions:

1) will VDINT0=0 cause no interrupts?

2)Is there any good user space program to access those registers? I am using http://designsomething.org/leopardboard/f/23/t/77.aspx

Regards,

Hongfeng

Ideally No. VDINT0 = 0 should have given you interrupts. Although it would mean that your buffer switching would not work correctly. But still the interrupts should have come. Can you check the polarity of the VD signal and see if it is correctly programmed in ISIF register?

 If you are using DVSDK2.x, you can use the attached utilities.

Anshuman

Thanks, Anshuman.

1) I am using DVSDK4.02, the readl in your attachement returns all zero when trying to read ISIF registers. But the readback from DM36x evm makes sense: VDINT=719, as expected.

I can use readl and writel to change register values on the EVM, but it always reads back zero on my board. This is consistent with previous observation: in ccdc_setwin(), right after regw(vert_nr_lines, VDINT0); the readback of VDINT0 is zero.

2) Since MODESET in EVM is also zero ( VD positive), I guess the VD polarity is not the cause. I just feel the whole VPSS module on my board behaves funny. Another strange thing may or  may not be related: once VFBE is initialized, the DM368 chip gets very hot. I haven't got the component video to work yet.

Best regards,

Hongfeng

Thanks to Anshuman and Vicent, I finally are making some progress.

I found a circuit design error causing VPBE over current thus the whole VPSS not working properly.

Now I finally see interrupts coming in!

Update:

Now the encodedecode -p runs fine, video_loopback_dm368.x470MV runs fine too.
But I still have trouble with the encode demo: it hangs after 5 frames every time, the interrupts counter keeps increasing though.
