Linux/DRA754: [Jacinto 6]Video capture failure: adv7182 decoder connected to vip

Moving this to the device forum.

Hi Ishaqe,

I have forwarded your question to VIP expert.

Regards,
Yordan

Hello, Can you please make sure that the VIP parser is detecting the video in correct sizes. Please read the VIP_PORT_SIZE registers (0x48995530 for vin3a) This would ensure that all the boardmux, pinmux, subdev related issues are clear. Thanks & Regards, Nikhil D

Its not detecting in the correct size. Read value of the VIP_PORT_SIZE (0x48995530) is 0x0 .

val = reg_read(port->dev->parser, VIP_PARSER_PORTA_SRC0_SIZE);
val is zero .

#devmem 0x48995530
0x00000000
But, from our side pinmuxing is done, not very sure about the other issues. subdev registration and working seems okay. Anyways, will check it again. Let me know if this can be debugged in any other way.
One more thing, sometimes register 0x48995530 read value is coming 0x05A00000. This is not always, most of the time in the first boot. This value is coming

# devmem 0x48995530
0x05A00000

That indicates the data coming to the parser is not stable.

Another way to find out the pinmux/boardmux issues is by probing the signals.
If you can, use CRO to probe the data/sync/clk lines.

OR use the GPIO software probe method.
Please provide me the dump of the pad register, I can attach the probe script for the vin3a

Regards,
Nikhil D

Thanks Nikhil D for the support.

Please find the vin3a pad register dumps;

shell~# devmem 0x4A00361C
0x00040104
shell~# devmem 0x4A0035D0
0x00040104
shell~# devmem 0x4A003620
0x00040104
shell~# devmem 0x4A003624
0x00040104
shell~# devmem 0x4A003628
0x00040104
shell~# devmem 0x4A00362C
0x00040104
shell~# devmem 0x4A003630
0x00040104
shell~# devmem 0x4A003634
0x00040104
shell~# devmem 0x4A003638
0x00040104

We will verify vin3a clk and data lines in Oscilloscope.
Please provide me more details of GPIO software probe method or probe scripts of vin3a. Is it to check connectivity with gpio?

Hi,

The GPIO probing method uses GPIO to find out if the data is toggling at the pad level.

Use the attached script based on the pad dumps you have provided.

I notice that you haven;t considered hsync/vsync You can get the full pad dumps using following command. omapconf dump 0x4a003400 0x4a00380c

Hi Nikhil,

the script shows as a long single line (maybe because of unix lineendings), I will just post it formatted:

Hsync and Vsync are not used. Configured to work on Embedded sync format.
Verified output of ADV7182 video decoder on oscilloscope. Output of ADV7182 seems correct. Verified pixclk (LLC), P0 and P7 data lines.

Not clearly understood the above script. Its only printing 0, like this continuously.

Probing VIN3A signals

omapconf binary is not present . That's why its failing. i will check with omapconf utility, but i think no issue in connectivity. Adv7182 signal starts coming on oscilloscope after streamon function.

Hi Nikhil,

Thanks for the support.

Sorry, last time when i verified this script, i was not running the capture application. I was not aware adv7180 driver has to be up and running. This is the output of your script, when adv7182 driver is inserted and it is powered on,

Pixel clk is running at 27MHz. Any configuration is required in vip for this?

Hi Nikhil D,

I think, its taken care in the subdev dtsi. Dts is as per tvp5158. Please check the below adv dt node.


/* ADV7182 Video encoder */

&vip2 {
status = "okay";
};

&vin3a {
status = "okay";
endpoint@0 {
slave-mode;
remote-endpoint = <&adv7182>;
};
};

&i2c2 {
status = "okay";
clock-frequency = <400000>;

adv7182-in@20 {
compatible = "adi,adv7182";
reg = <0x20>;

port {
adv7182: endpoint {
buswidth = <8>;
remote-endpoint = <&vin3a>;
channels = <0>;
};
};
};
};

Hi Nikhil D,

#devmem 0x48995530
0x02D00120

Now, parser is getting stable data.

if (endpoint->bus.parallel.pixmux == 0) {
sync_type =
EMBEDDED_SYNC_SINGLE_YUV422;
//EMBEDDED_SYNC_LINE_MULTIPLEXED_YUV422;

}
Setting Sync_type to Embedded sync single yuv422, sync_type was getting changed because of pimux =0.
Hard-coded the config value for time being,
reg_write(parser, VIP_PARSER_PORT(port->port_id),0x100);


So, this confirms parser getting the stable data from adv7182 decoder.
Please let me know if there is any other register to confirm data to VIP_CSC, VIP_SC and VPDMA.

Issue is still there. No interrupts to vip. Frames are not getting captures.
For more information, added the complete vip log in my first comments.

Thanks,
Akshay

VIP_FIQ_STATUS value is 0x00014C00 . Port A Disconnect FIQ is problem?

Format difference is there between adv7182 and vip driver, Adv7182 code is "MEDIA_BUS_FMT_YUYV8_2X8" and vip code is "MEDIA_BUS_FMT_UYVY8_2X8". ADV7182 bt656 is YCrCb. Doubting its because of this mismatch. To support this added below change in vip, driver; please check it and let me know if its not correct;

{
.fourcc = V4L2_PIX_FMT_YVYU,
.code = MEDIA_BUS_FMT_YUYV8_2X8,
.colorspace = V4L2_COLORSPACE_SMPTE170M,
.coplanar = 0,
.vpdma_fmt = { &vpdma_yuv_fmts[VPDMA_DATA_FMT_Y422];
},
},

VIP_FIQ_STATUS value is 0x00014C00, Correcsponding mask register is 0x0. Though, PORT_A_YUV_PROTOCOL_VILOATION bit is set, other bits are also 1. This should atleast trigger one interrupt. Not sure why no interrupts are coming for this.

Hi Nikhil

Logs are shared in the first comment. Same logs will get for dmabufftest. vip related logs are enabled in it. I have used capture_raw_frames applicaiton. Please check that log. Will share the log with dmabufftest in sometime.

As mentioned in the previous comments, VIP_FIQ_STATUS value is 0x00014C00 and 0x48995530 VIP_OUTPUT_PORT_A_SRC0_SIZE is having value 0x02D00120

Akshay

Hi Nikhil,

This is the output with dmabuftest command. Its stops in "will sleep waiting for buffers", doesn't proceed further.

Hi akshay, First, The VIP hardware expects ONLY UYVY type of media format. Most likely the decoder you have would also be generting output in UYVY format. Please confirm this. Also, I see that there are no IRQs getting fired for any of the VIP instances/slices. Even if the camera is not connected, video is not present, you should have seen two IRQs fired. First two IRQs get fired from VPDMA FIFO after it accepted the DMA request. I don't see that happening, Is there any change you did with respect to IRQ enablement or IRQ crossbar? Regards, Nikhil D Regards, Nikhil D

Hi Nikhil D,

Thanks a lot for the support. Now, interrupts are coming:). Below are the changes.
1. Forced sync_type to EMBEDDED_SYNC_SINGLE_YUV422. This was the only change required in the vip side.
2. Changed vip format code to "MEDIA_BUS_FMT_YUYV8_2X8". Tried this change in vip and changed adv driver code to MEDIA_BUS_FMT_UYVY8_2X8, with replacing cb and cr to YCbCr format.
3. Removed debug messages which i had added earlier to know the code flow. Few debug messages were in "enable_irq" and "start_dma" functions. Removed these and started getting interrupts.

Captured frames are not able to play properly on yuv player. I think its because of format mismatch. ADV7182 output is in YCrCb 8bit 656 data. VIP expects in UYVY format. Is because of this? In ADV7182 side i can change output to YCbCr format.

I have doubt in the height and width;

Thanks for the support Nikhil Devshatwar . ADV7182 Bringup is done and camera is working as expected.
