Export YOLO to executorch for RISC-V Baremetal environment

[vaibhavmindgrove22]

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.

1. Is this realistically possible to be done without using XNNPack (which relies on pthreads and pthreads require an OS)?
2. Or can I run YOLO with XNNPack backend without using pthreads?
3. 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.
