TDA4VM: Consultation on EE-related issues

Part Number: TDA4VM

Tool/software:

Hi,
I'm currently tuning the ISP and have encountered some issues. My current SDK is LinuxEdge AI-09_02_00_05. How can I enable ee_mode?

1. I've made the following modifications in

/opt/edgeai-gst-plugins/ext/tiovx/gsttiovxisp.c: static const guint default_ee_mode = TIVX_VPAC_VISS_EE_MODE_OFF->TIVX_VPAC_VISS_EE_MODE_Y8;

then ran ./scripts/install_gst_plugins.sh. After testing, the ee_mode did not take effect.

2. I also saw your reply on the forum. I've tried both methods you suggested, but EE still doesn't take effect.

Could you please help me? I've been stuck with this for a long time.

Thank you!

Hi Ying,

I assume this is the FAQ being referenced: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1491791/faq-am62a7-how-to-enable-edge-enhancement-on-tda4x-am6xa/5729480?tisearch=e2e-sitesearch&keymatch=Enable%20edge%20enhancement%20by%20setting%20ee_mode#

Instead of install_gst_plugins.sh, the FAQ uses install_tiovx_modules.sh to rebuild. Can you retry method 1 with install_tiovx_modules.sh?

Regards,

Takuma

Hi,

My SDK version is 09-02-00-05. The file /opt/edgeai-tiovx-modules/src/tiovx_viss_module.c does not contain ee_mode, so rebuilding with install_tiovx_modules.sh has no effect. Moreover, as stated in the FAQ, versions 9.2 and above should use GStreamer to enable ee_mode, which I have tried, but EE still doesn't take effect.

Thanks.

Hi Ying,

Can the GStreamer pipeline being used to test be shared? I would like to take a look at it to see if there is anything that stands out, and it will be useful to replicate your setup.

As you mentioned, yes, 9.2 and above should have ee_mode integrated, so it is unexpected that EE is not taking effect.

Regards,

Hi,

Here is my GStreamer command. Could you please help me check if there's any problem with it? Thanks.

Hi Ying,

Currently looking into it. In the meantime, feel free to test with the latest 11.0 SDK in case there were bug fixes between 9.2 and 11.0 SDK.

Takuma

Hi Takuma,

Thank you very much for your help. However, I still hope to use the EE effect on version 9.2. I tried to port the X3C driver, EdgeAI components, and other parts to version 11.0 today, but encountered many errors.

Hi Ying,

So far, not finding any visible changes with ee_mode enabled/disabled in 9.2 SDK same as you.

I did take a look into the source code of the gstreamer plugin for the ISP and I did find something a bit suspicious.

This looks to be the patch that adds support for ee-mode within the plugin: https://github.com/TexasInstruments/edgeai-gst-plugins/commit/97d1758536e823252ea0f17e0fe1978b379994e3
However, as you can see from line 1578 in the code, this support for ee-mode was added in a block of code that only gets enabled for J722S and AM62A: https://github.com/TexasInstruments/edgeai-gst-plugins/blob/main/ext/tiovx/gsttiovxisp.c#L1578. This will be an issue for TDA4VM

Will check with team to see if TDA4VM is supposed to support ee-mode (I assume it does), but as a quick workaround, you can hardcode and rebuild the gstreamer plugin to have a different default value for ee-mode.

Regards,

Takuma

Hi Takuma,

Thank you very much. Using the method you provided, I have temporarily resolved the issue where EE was not taking effect.

Hi Ying,

Thanks for the feedback! We will see if we can implement a bug fix in future SDK. For now, would it be fine to close this thread as resolved?
