[HailoRT] Status 77 error happens!

Dear community members,

I need to implement multiple models on a Raspberry Pi-based system. Due to previous issues with the hailo_platform library, I am attempting to use the GStreamer library instead.

I have encountered a new error with status code 77.

Here is the pipeline string along with the error code. Please provide any comments or documents that could help.

Thank you for reading.

Have a look into the HailoRT User Guide. You can download it in the Developer Zone. Here are a few pointer from the guide:

To enable and start the service, run:

sudo systemctl enable ­­now hailort.service

If service is enabled but not active, run:

sudo systemctl start hailort.service

To see the service status and make sure it is active, run:

sudo systemctl status hailort.service

Hmm…

Thank you for your comments.

I think I have already activated the HailoRT, but I will retry it carefully.

After doing that, I will reply with the results again.

Thanks to your comments,

I found that the HailoRT services are unintentionally disconnected.

I restarted it manually and successfully passed the errors to the next step.

Some new issues have occurred, but they seem to be related to the pipeline structure.

I will handle it. Thank you for your help.
