yes - it sounds like the problem... from William's blog, I'd look at this part $ sudo apt-get install git $ git clone https://github.com/beagleboard/bb.org-overlays $ cd bb.org-overlays/ $ ./dtc-overlay.sh $ sudo ./install.sh
and then check that the overlays in /lib/firmware are current. BTW, backup any data before following my comments.... cheers On Thursday, 25 February 2016 09:59:58 UTC+1, Thomas Andrews wrote: > > I have just upgraded to a 4.5.0-rc4+ kernel that I built, and I'm having > trouble getting SPI0 and UARTs 1 & 4 working again.
