TDA4VE-Q1: Does the DisplayM2M node support image format conversion with a resolution of 2560 * 1440?

Hi,

Is this a duplicate question?

Regards,
Tanmay

The platform I am using is TDA4VE, and I made a mistake with TDA4VM, but I don't know how to delete the previous one, so I had to raise this issue again.

Hi Damon

What app are you used to test dispm2m color convert?

Regards,

Adam

Hi Damon,

Can you share your graph creation part with the config values, and also how are you save the image ?

Gokul

Hi Adam

We are using our custom app for testing. Is there a demo here for us to test?

Thank you.

Hi Damon,

Can you try this test program video_io/kernels/video_io/test/test_display_m2m.c?

run ./vx_app_conformance_video_io.out --filter=tivxVideoIODisplayM2M* under /opt/vision_apps/

Regards,

Adam

Hi Adam

I have already tested this program, and the results are as follows.

Before the resolution is modified, the program can run normally

Regards,

Damon

Hi Damon,

Can you please check this in latest sdk once, we saw some issue on 9.1 at higher resolutions.

Regards,
Gokul

Hello Gokul,

I am using SDK version 0901. Do you have any updated versions available for us？

Regards,

Damon

Hi Damon,

Can you try with the latest sdk version 11.00.

https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-50weZVBfzl/11.00.00.06/ti-processor-sdk-rtos-j721s2-evm-11_00_00_06.tar.gz

Regards,
Gokul

Hello Gokul,

We don't have the hardware for this TDA4 VE demo board. How can I verify it, Or do you have any other solutions to verify？

Regards,

Damon

Hi Damon,

You should be having an evm right ? or is that a custom board that you have tested with sdk version 9.0.

Can you share your input image here so that I can give a try in my setup here If i find some time.

Regards,
Gokul

Hello Gokul,

Can the SDK 11.00 you provided run on evm bord? Please provide me with an email so that I can send you images in RGBX format. It seems that uploading images in this format is not supported.

Regards,

Damon

Hi Damon,

Yes it will run on evm and it is the latest sdk release.

Can you add it inside .zip file and upload it.

Regards,
Gokul

Hello Gokus,

I tried running the SDK program on the EVM board and found that it failed to start. I tried running our program on our own 0901ve board again and found that when the resolution width is greater than 2048, the abnormal situation occurs when the output image format of the displayM2MNode is set to NV12 (which isnormal when the output format is set to yuyv). Can you give me more advice？

Regards,

Damon

Hi Damon,

Can you share the writeback pipe register dumps, 

from address (0x4af0000UL) and till the size of this struct,

Regards,
Gokul

Hello Gokul,

I don't understand what you mean by this. Should I use any tool to operate it or check through logs？

Thanks,

Damon

Hi Damon,

While running your application in another linux terminal run this script,

#!/bin/bash

BASE_ADDRESS=0x04af0000

for (( i=$BASE_ADDRESS; i< ($BASE_ADDRESS + 588) ; i+=4 ));
do
  # Commands to be executed
  echo "Reading register at $i:"
  devmem2 "$i"
done

This will dump the writeback pipe registers.

Regards,
Gokul

Hello Gokul,

The result of the operation is as follows. Please help analyze it.

Hi Damon,

Are you cropping your image from input to output and can you share your input and output image size.

Regards,
Gokul

Hello Gokul,

My requirement is to crop the output image of Display M2M into 2 parts, with an input size of 2560 * 1440 and an output image size of 832 * 1120, 1568 * 1120.

Regards,

Damon

Hi Damon,

So are you using 2 displaym2m node ? with 2 different output image. The image you posted for which case ?

Regards,
Gokul

And also can you check with only one output with either 832 * 1120 or 1568 * 1120

And the register dumps you shared is for which configuration.

Regards,
Gokul

Hello Gokul,

You misunderstood my meaning. I am using a scaler node downstream of the display M2M node for crop. As for the input and output resolution of the display M2M node, they are both 2560 * 1440, displayM2M only for changing the color format RGBX ->NV12

Regards,

Damon

ok, Got it,

you are using 1 displaym2m node to convert the color and both the input and output image size's are same.

we are seeing some difference in values between 2 registers ( 0x04AF0208 and 0x04AF0210 ) which is the output and input size registers. Ideally the values should be same if the input and output size is same. Can you check for yuyv output whether this 2 values are same ?

Regards,

Hi Damon,

I have created a jira for this bug attaching the link for internal tracking https://jira.itg.ti.com/browse/PDK-18111?filter=-2
This should be fixed in the next sdk release.

I am closing this thread since the issue is resolved.
