Dear Forum,
I have been testing various overlays, some loads without problems, other won't load but can be manually loaded after boot. I can even rename an overlay that loads and it stops loading even if the content is identical.
I have tested the suggested solutions from:
http://elinux.org/BeagleBone_Black_Enable_SPIDEV
The .dtbo files does not load at boot, but can be loaded manually later.
The boot log gives no hints of the problem.
Please advice
Best regards
Terje Froysa
