HA OS on Beaglebone Black

Hi !

I"m trying to build a image from sources on adding a board in :

I’ve build an xz image, and boot is Ok.
I can reach the serial console ha>.

In systemd logs, i have some depencies issues … i do not yet understand the root cause.

I’ve setup HA packages like this since the Rpi2 being with cortex A7 is near cortex A8 CPU :
BR2_PACKAGE_HASSIO=y
BR2_PACKAGE_HASSIO_ARCH=“armv7”
BR2_PACKAGE_HASSIO_MACHINE=“raspberrypi2”
BR2_PACKAGE_OS_AGENT=y
BR2_PACKAGE_OS_AGENT_BOARD=“RaspberryPi2”

What woud be the HASSIO and OS_AGENT to set ?

What are the metadata ::
SUPERVISOR_MACHINE, SUPERVISOR_ARCH: does it correspond to BR2_PACKAGE_HASSIO_* ?

I choose ‘tinker’ for Hassio machine and ‘Tinker’ for os agent. I resolved dependencies issues, it was due to Linux firmware packages missing in my buildroot config for BeagleBone.
It seems to work well.
Is there some maintainer of ha os there ?
I feel strange to specialize by board the os agent an supervisor, why not common ?
