Can this beaglebone AI run raspbian OS?

There is absolutely zero point to running “rasbian” on any beagle hardware. None of the software that is used for interacting with the outside world would work. Granted, networking should work, USB connectivity may work depending.

As stated several times. Rasbian is just RaspberryPI(hardware) specific Debian. Well I do believe there is also an Ubuntu branch, but again . . . Ubuntu is based on Debian.

Now is you’re wanting someone to setup Debian for you, with all the bells and whistles that comes with Rasbian. Be prepared to pay someone tens, if not hundreds of thousands of dollars. It is however doable.
