TDA4VM: CSI1 app_multi_cam

When numChan is set to 2 in

static IssSensor_CreateParams gw_ar0233CreatePrms = {

1,   /*numChan*/

}

Max number of cameras supported by sensor GW_AR0233_UYVY = 1

Please enter number of cameras to be enabled

1

./run_app_multi_cam.sh The stuck log is also the same.

app_run_graph_for_one_pipeline: frame 1 beginning, pipeline:-2,line:1264

app_run_graph_for_one_pipeline: frame 2 beginning, pipeline:-1,line:1264

What modifications can we try? Please help us support.

Barry

Hi,

For the single cam, you are connecting on CSI1 port (i.e. port 4) right?

Are you connecting the 2 cam also only on CSI1?

I think multicam demo would require a continuous cameras on all ports till port 4 or 5, 

i.e. if you give number of sensor as 2, it expects the sensor to be at port 0 and 1. Have you modified the demo to take this into consideration?

Nikhil

Hi expert,

thank you for your reply .

After we set sensorObj->ch_mask = 0x30, he started working.

We want to convert the YUV422 UYVY of capture into RGB565. How should we implement this conversion node?

Looking forward for your reply, thank you

Regards,

Barry

Hi TI expert,

Are there any supported nodes for converting yuv422 to rgb565? Please help us confirm.

How do we need to implement this function?

Looking forward to reply, thank you

Regards,

Barry

Hi Barry,

YUV422 to RGB565 conversion could be done by the DSS_M2M node.

The output image format on OpenVX would be TIVX_DF_IMAGE_RGB565 and the input format is VX_DF_IMAGE_UYVY.

Regards,

Nikhil

Hi Nikhil,

thank you for your reply,

We are doing:

PDK-RTOS:processor-sdk-rtos-j721e-evm-08_06_00_12

PDK-LINUX:processor-sdk-linux-08_06_00

After I used m2m node to set the data type to TIVX_DF_IMAGE_RGB565 in run_app_multi_cam.sh, the error was reported as follows:

When I add TIVX_DF_IMAGE_RGB565,graph started working.

kernels_j7/hwa/host/vx_display_m2m_host.c:

Hi Nikhil,Brijesh,

The attachment tie2e1.zip upstairs is the output display after we add the conversion node.

What configuration did we miss? Or is there a problem with the settings somewhere?

What can we try?

Looking forward to your reply, thank you

Regards,

Barry

Hi Barry,

The display m2m node has 3 parameters. 

1. Display configuration - Can you share what is the display m2m parameter struct values you have set in the application? i.e. pipe, overlay etc..

2. Input image and output image - Can you let me know the parameters given to vxCreateImage() for input and output?

Regards,

Nikhil

Hi Nikhil,

Can you tell me what I missed? Looking forward to the expert's reply.

Barry

Hi expert，

Can you update it for us?

Regards,

Barry

Hi expert，

We need to convert the captured YUV422 to RGB565, and then send the RGB565 to the display node for display.

1.If TDA4VM M2M node does not support converting YUV422 to RGB565 ,

Please respond to us with a clear conclusion, thank you

2.If the captured YUV422 can be converted to RGB565 before displaying,

how should it be changed?

Please reply for us, thank you

Regards,

Barry

Hi Barry,

Sorry for the delay in response.

The implementation looks fine to me.

Could you read the register 0x04AF0020 and let me know the value? This should tell if the format is set correctly. The value expected to be set for RGB565 is 0x3 in the register bit [1:6] and the enable should be 1 [bit 0]

Let us continue the discussion in this thread and close the below thread to avoid duplication.

Hi Barry, 

The configuration looks fine, I would have to try and reproduce this at my end to check what the issue is. 

I will take the single cam example to begin with and do capture (UYVY) -> display m2m (RGB565) -> display and let you know the result.

Meanwhile, the image that you shared, was that from the output of display (i.e. seen on the display) or the output of dss_m2m?

Regards,

Nikhil

Hi Nikhil,

Your reply is important to us.

I found that when I run in ./run_app_multi_cam.sh, pressing 'S' on the console has no effect and cannot save the image.

Therefore, the picture ZIP I uploaded came from the screen display, and I recorded a short video.

rgb565.zip

It seemed that there was no problem in real time, but the display was still abnormal. (Both pictures and videos come from the display, and are both

obj->fmtConvObj.color_format = TIVX_DF_IMAGE_RGB565 Phenomenon after adding)

Looking forward to your reply.

Regards,

Barry

Hi Barry,

Can you please save 150 registers from offset 0x04AF0000? Lets see if it is configured correctly.

Regards,

Brijesh

Hi Brijesh,

Our development board currently does not have network and CCS interfaces.

What method can we use to dump these registers while ./run_app_multi_cam.sh is running?

Regards,

Barry

You can use k3conf utility or memdump utility from Linux.

Regards,

Brijesh

Hi Brijesh,

thank you for your reply

But after run_app_multi_cam.sh is run, the serial port cannot be input. In this case, is there a patch we can refer to?

Regards,

Barry

Well, you can run in background mode or if you have ethernet connected, you can do telnet to the board and then can get the register values. 

Regards,

Brijesh

Hi Brijesh,

thank you for your reply

Hi Barry,

Thank you for sharing the registers. We will go through this. 

Meanwhile 2 experiments from your end.

1. I believe you are running 2 cam in the multicam demo right? Could you run just 1 cam and check if you are seeing this issue?

2. I did a change in the single cam demo by adding the dss_m2m to this which outputs RGB565 format to the display node. Since I do not have a YUV sensor with me, I tested this using the YUV422 testpattern from the UB960 Deserializer, and i was getting the expected output.

Could you apply this patch and let me know if you are able to stream your sensor by converting it to RGB565 by DSS_M2M?

/cfs-file/__key/communityserver-discussions-components-files/791/dss_5F00_m2m_5F00_single_5F00_cam.patch

If you are able to stream with this, then there would be no issue with the node.

Nikhil

Hi Nikhil，

thank you for your reply.

1. I believe you are running 2 cam in the multicam demo right? Could you run just 1 cam and check if you are seeing this issue?

      -----, I only enabled 1 camera in the multicam demo, and the result was the same as executing the singlecamera demo;

2. I added the patch, and it looks the same as the effect I had after adding M2M in the multicam demo.

Here is the YUV image saved after I added the patch and executed singlecamera demo and pressed 'S':

capture parameter input:1920*1536

YUV file name /opt/vision_apps/test_data/cap_0001.yuv

imgaddr_width = 1920

imgaddr_height = 1536

imgaddr_stride = 3840

width=1920

height=1536

i 9324...

cap_yuv.zip

And the output seen on the display (taken picture):

display parameter output: 1280*800

Hi Nikhil，

Our purpose is to make the camera output to the display screen for normal display;

1. When I run run_app_single_cam.sh and press 'S', the saveimage looks OK, as follows:

img_width = 1920

img_height = 1536

cap0002.zip

2. But the screen display as follows is abnormal:

disp_params.outWidth  = 1280;

disp_params.outHeight = 800;

origin.zip

The data flow is:

TDA4VM->DSI->max96789->max96752->lcd (LCD is the LVDS interface)

3. We also tried to convert the format to TIVX_DF_IMAGE_RGB565 for output, and the screen display changed but it was still abnormal:

fmt.zip

How can we make the screen display properly? Can you send us a thread with related questions? Please help us,thank you.

Looking forward to the expert's reply

Regards,

Barry

Sorry, i am a bit confused here.

Your graph is the below right?

(A) Capture node (UYVY) -> Display M2M node (UYVY -> RGB565) -> Display node

Are you able to get correct output on the display with the below graph?

(B) Capture node (UYVY) -> Display node

If you are getting correct display above, then have you tried the below

(C) Capture node (UYVY) -> Display M2M node (UYVY -> UYVY) -> Display node

So from the above (A) (B) and (C), which are the working and non-working scenarios?

You had shared (2) and (3), this is related to which one among (A) , (B) and (C)?

Regards,

Nikhil

Hi Nikhil，

thank you for your reply.

Our goal is that the output from the camera to the screen can be displayed normally.

Because the output display was abnormal, we tried to add an M2M conversion node and found that the output was still abnormal.

The M2M node is a test we did ourselves. If it misleads you, please ignore point 3 I mentioned above;

So our question is:

1. When I run run_app_single_cam.sh and press 'S', the saveimage looks OK, as follows:

img_width = 1920

img_height = 1536

1207.cap0002.zip

2. But the screen display as follows is abnormal:

disp_params.outWidth  = 1280;

disp_params.outHeight = 800;

3364.origin.zip

The data flow is:

1920x1536 Capture node (UYVY)-->DSI->max96789->max96752-->1280x800 LCD (lcd is the LVDS interface)

Looking forward to your reply.

Hi Nikhil,

Hi Brijesh,

This problem troubles us very much. We hope to get your support. Thank you.

Ok, now since the Display M2M is out of the picture and the capture node is giving output correctly, that would leave us with your display.

Did you bring your display up before? i.e. is the configuration of the serdes and that path been validated with some known data?

Nikhil

Hi Nikhil,Brijesh,

I solved this problem by configuring max96752.

Thanks to the experts for their support, close this question.

Barry
