TDA4VEN-Q1: Surround view demo environment for J722SXH01EVM

Hi Ryuuichi Machida,

What surround view demo kit are you referring to?

Can you send a link to what you are referring to?

Hi,

What I expect is kind of below.

This is case of TDA3 + FPDLINK with multi camera, but I would like you to confirm whether you have similar solution for TDA4VEN as well.

Best Regards,

Hi Ryuuichi Machida,

We have documentation on a surround view demo for the J721E, J721S2, and J784S4.

• https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/group_apps_srv_demos_app_srv_camera.html 
• https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/latest/exports/docs/vision_apps/docs/user_guide/group_apps_srv_demos_app_srv_camera.html

There is nothing for the J722S, but the code may carry over. I'm unsure whether it would though.

I will loop in our expert on this, and they may have more information.

Jared

Hi Jared-san,

Do you have any update about below ?

Hi Ryuuichi Machida,

Our expert has been out of office, and will return tomorrow.

Hello,

I found following information on RTOS SDK release note.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j722s/latest/exports/docs/psdk_rtos/docs/user_guide/evm_setup_j722s.html#evm-setup-to-run-sdk-demos

According to this, user can connect 4 camera with Fusion daughter card.
I could not find surround view information for this configuration, but do you know what kind of demo user can peform under this configuration ?

Best Regards,

Hello,

Unfortunately, there is not an available public facing surroundview demo for the j722s device. I do have some internal facing j722s GPU metrics on a surround view application that I can provide if interested but that is all the available support for this. The actual application to replicate and run is not available.

Thank you,
Sarabesh S.

Hi,

Thank you for you reply.

Is it kind of benchmark when you perform surround view simulation ?
Could you please share it to us ?

Hi,
Thank you for your reply.
I will check it later.

In addition, I would like to confirm whether you have 3rd party solution.

I found following article about surround view.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1433722/am62p-q1-is-there-a-surround-view-demo-using-gpu-on-am62p

This described that it seems Cogent Embedded provide surround view demo for AM62P.
Do you know whether they have same demo for TDA4VEN or not ?
(AM62P and TDA4VEN have same Cortex A core, so I expected that they have widespread.)

Hi,

Thank you for your reply.

After looking into it some more, I found that there is a patch available that you can apply to 11.0 Vision Apps SDK to enable SRV on J722s located in this FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1525702/faq-tda4aen-q1-enable-srv-surround-view-node-on-j722s

Could you show your hardware setup information about above ?
(What I would like to confirm is what kind of daughter board and camera you use.)

Best Regards,
