Hi @chris,

We’re sorry to hear that you’re encountering issues. Could you please share what you tried to run and the error message you get?

Well that’s just the thing i’m not getting errors. I followed these guides but when I try to use the demos from Rpicam It does nothing but show my camera.

Here’s another tutortial I a currently follow it is a video

Want let me add it here but its hailo’s official video title ( Raspberry Pi AI Kit - Unboxing and Installation Guide) posted two months ago

when I get to the part where you activate the environment (source setup_env.sh) I get this output

Setting up the environment…
Setting up the environment for hailo_tappas…
TAPPAS_WORKSPACE set to /home/taxzilla/Downloads/tappas_v3.29.1
TAPPAS_VERSION is 3.29.1 not in the list of required versions 3.28.0 3.28.1 3.28.2.

Hey Chris,

We noticed that although you’ve upgraded HailoRT to version 4.18, TAPPAS also needs to be updated. Here’s what you should do:

  1. Update TAPPAS to tag 3.29.1 from the latest GitHub release.
  2. Create a new environment.
  3. Install the updated TAPPAS version in this new environment.

Following these steps will ensure that you’re using the compatible version of TAPPAS with HailoRT 4.18. Let me know if you need any assistance with this process.

Hello in the post above notice I put what the terminal said Ill repeat here

when I get to the part where you activate the environment (source setup_env.sh) I get this output

Setting up the environment…
Setting up the environment for hailo_tappas…
TAPPAS_WORKSPACE set to /home/taxzilla/Downloads/tappas_v3.29.1
TAPPAS_VERSION is 3.29.1 not in the list of required versions 3.28.0 3.28.1 3.28.2.

so it looks like it it is version 3.29 but looks like it is requiring version
3.28.0 3.28.1 3.28.2. which is not in the list because I have version 3.29

You are missing the post processing stages, how did you compile rpicam-apps?

I just simply followed this tutorial, which basically you just clone the git hub then enter the following scripts in the terminal

Hey @chris,

If you have TAPPAS 3.29 installed, then you’re using HailoRT 4.18. To use the rpicam apps, you need to have HailoRT 4.17 and TAPPAS 3.28. These apps are maintained by RPI, and they will update them to be compatible with TAPPAS 3.29 when they move to HailoRT 4.18.

Okay thank you omria, is there any other way I can test and see if my halio is actually working on my rpi?

14

Certainly, there are two steps you can take to verify your device’s status:

  1. Check if the system recognizes the device: Run this command: hailortcli scan
  2. Verify the firmware version and other details: Execute: hailortcli fw-control identify
