@yan-wyb The Coral device is detected but I see, " Capabilities: ". I have seen this before butunable to recall the exact issue. I'll try to look in the previous issues and will get back to you.

[manoj7410]

@yan-wyb Is the correct kernel header installed on your machine ? Have you tried with the recent kernel versions?

[yan-wyb]

I'm sure the kernel headers are installed, the system is maintained by ourselves, I'm from the Khadas team. The latest 5.16 kernel can be used normally. 4.9 kernel is the version provided by the vendor, which is also very important to us. Many users hope to support this version.

Any update ? @manoj7410

[boredcoder411]

I'm having the exact same problem, on a similar system. I've ran the basic example (the one with the parrot) successfully, but I'm trying the movenet out, to no avail
