YOLOv8 custom model HEF compilation error on Hailo-8 with HailoRT 4.20.0

General Discussion

Device: Seeed Studio reComputer AI R2000
Hailo chip: Hailo-8
HailoRT version: 4.20.0
OS: Raspberry Pi OS Bookworm 64-bit
DFC version: 3.33.1

Problem:
I compiled a custom YOLOv8 model (2 classes, imgsz=416) to HEF using DFC 3.33.1.
When running on device I get:
“firmware major status: context_switch_task_status_received_invalid_application_count”

Steps I followed:

  1. yolo export model=best.pt format=onnx imgsz=416
  2. hailo parser onnx best.onnx --hw-arch hailo8
  3. hailo optimize best.har --hw-arch hailo8 --use-random-calib-set
  4. hailo compiler best_optimized.har --hw-arch hailo8

Which DFC version is compatible with HailoRT 4.20.0?
