HI

How to deal with this problem, I can't start now.

Can you provide more information in your case?

1.The version of your chip

2.The software version of your bsp

3.Does this issue can be reproduced on MEK?

4.The detailed reproduce steps and full error log.

[songhongliang]

HI

1. chip is imx8ux

2.bsp is linux5.4.70-2.3.4

3.Can be reproduced on MEK。

        nxp surround view demo, surround-view-3D_1.1_beta, the capturing application。

       #cd surround-view-3D_1.1_beta/Tools/CamCapture

      # ./capturing

4.log please see the attachment

[Zhiming_Liu]

Hi @songhongliang 

What cameras customer you are using?

Can you provide the chip number? You can find it on Chip.

[songhongliang]

hi 

I am using TP2815， AHD to MIPI.

[Zhiming_Liu]

Please check the log, the camera can't work.

1.The surround-view software is compatible with the surround-view system we distribute.Do you have same surround-view system?

https://www.nxp.com/design/designs/i-mx-surround-view-system:SURROUND-VIEW-APPLICATION

2.We haven't test surround-view software on i.MX8DX, as the lasted surround-view software is released in 2018, but the i.MX8DX is newest.We need your chip number.i.MX8QXP&i.MX8DX B0 chip has one errata which can't support 4 cameras.

[songhongliang]

HI,

我看到关于imx8x系列的环视系统的文档已经更新了，是不是相关的demo也已经在测试了。能不能提供一个demo，我这边也尝试一下。

谢谢！

[songhongliang]

你好

我使用的是MIMX8UX6AVLFZAC，使用命令gst-launch-1.0 v4l2src device=/dev/video1！autovideosink，可以正常获取图像，使用其他命令也可以同时获取四路图像在界面上。我没有与你们相同的环视系统。这个是2018年分发出来了，nxp有打算对这个环视demo进行更新吗？附件是gst-launch-1.0命令执行的log

[Zhiming_Liu]

As we have not tested it on the i.MX8DX before, the advice given by the experts is that you need to modify the source code by yourself, as there is a camera driver error in your log, so it could be that the camera driver does not support the ioctl operation in the software.

[songhongliang]

HI,

This error does not seem to be related to the camera driver. I checked the corresponding driver and modified the function corresponding to the ioctl. The error still exists. I checked the corresponding frame rate and resolution between the driver and the application, and the two are consistent.

Thanks

Hi

Reply from software service team:

Pro-support can handle this for support in new bsp porting and new requiement.

HI

It’s really great to add support for new BSPs. Does the software service team have time to plan? It’s entirely possible to create a repository on GitHub for easy updating

Thanks
