Great.
Here’s what you need to do:
- Take as a reference this repo (odroid files) github.com/volumio/platform-odroid
- In here, place a tar.gz which will include the following hardware related binaries
boot
etc
lib
uboot - Make a pr here github.com/volumio/platform-banana-pi
Then we can move forward, your best bet is to take inspiration from the odroid repo
Let me know!
