BeagleY-AI: Support for NPU?

[dmidge]

Hi folks,

 

I was looking to activate the NPU on my beagley-AI chip, running armbian, and I couldn't find how.

This chip as a NPU (AM67A) on the SOC from TexasInstruments (https://api.pageplace.de/preview/DT0400.9783895766572_A50990365/preview-9783895766572_A50990365.pdf).

 

The loading of the NPU seems to have failed:

The usual lspci doesn't contain much:

lspci
00:00.0 PCI bridge: Texas Instruments Device b010

 

How should I proceed to make it work?

Thanks!
