DeGirum ORCA USB accelerator on a Raspberry Pi 5 (ARM64) w/PiOS

General

Hello all, I’m trying to use a **DeGirum ORCA USB accelerator on a Raspberry Pi 5 (ARM64) running Trixie and looking some guidance.

Here is the snapshot so far:

  • OS: Raspberry Pi OS 64-bit (Debian Trixie)
  • Hardware: Raspberry Pi 5 + ORCA USB
  • PySDK installs and runs correctly (Python 3.12)
  • degirum sys-info works (CPU runtimes visible)
  • Inference server runs
  • ORCA .n2x models download and load successfully

Inference fails with:
“Requested inference device type ‘N2X/ORCA1’ is not found in the system”

Running:
“degirum install-runtime --list”
shows no n2x_orca* runtime available** on Raspberry Pi OS

Question:

  • Is the ORCA USB runtime officially supported on Raspberry Pi OS, or is ORCA USB currently supported only on other Linux distributions (e.g., Ubuntu)?

Thanks

Hi @shashi, thank you for your response and suggestion:
I ran the Ubuntu steps for 24.04 and I am up and running, just make tweaks to optimize. Thank you for you help and support

Hi @mrnavi

Gret to hear that you are able to run on Orca USB. Please feel free to let us know if you need any help with application development. If you are interested in face recognition applications, you can try our degirum-face package: Introduction | Face Recognition | DeGirum Docs
