Description
I am trying to do object detection using YOLO on a RISC-V baremetal environment. The RISC-V core I am using is single core. It supports IMAFDC. I saw that exporting YOLO to executorch requires XNNPack backend. I have a few questions.
- Is this realistically possible to be done without using XNNPack (which relies on pthreads and pthreads require an OS)?
- Or can I run YOLO with XNNPack backend without using pthreads?
- Also if there is no OS, will this run in single threaded mode in baremetal and not give any errors?
Any help regarding this would be appreciated.

Research direction
Start by reviewing the ExecuTorch export path for YOLO and the XNNPack backend assumptions described in the issue. Check how pthreads and single-threaded execution are handled for a RISC-V baremetal target. Done should be a clear supported configuration or an actionable implementation scope answering the three compatibility questions.
