Is SPI Working?

[x893]

The issue is related to the fact that current DT is loading a "jedec,spi-nor" driver.
You will need to edit the main DT and remove the "spi-flash@0" section.
Then you will be able to load the overlay, but it need to be done in armbianEnv.txt, not uEnv.txt which doesn't exist in Armbian.

(Or wait few more days, until I'll fix the issue in future builds)

Thanks !
I'll wait some days.
