For what it's worth Bluetooth stack does not work out of the box on EL7 armhfp architecture and RPi3. One needs: 1. patch bluez-utils a bit since hciattach attempts to get the files from the wrong directory 2. firmware for brcm 43430 isn't supplied with EL7, I had to get it from another source 3. udev doesn't know to check the presence of 43430 so one needs to make a rule for that, too Other than that, ethernet, wifi and everything else I've tested works quite well. I haven't tried with the serial ports in 232. 😊 Kaj -----Original Message----- From: Bill Maidment [mailto:[log in to unmask]] Sent: 17 November, 2017 07:32 To: Kaj Niemi <[log in to unmask]>; [log in to unmask] Subject: RE: SL7.4 for ARM ? Thanks Kaj I've got it running, but it looks like it will need a bit of work to get it fully implemented. -----Original message----- > From:Kaj Niemi <[log in to unmask]> > Sent: Thursday 16th November 2017 18:48 > To: Bill Maidment <[log in to unmask]>; [log in to unmask] > Subject: RE: SL7.4 for ARM ? > > You might want to read https://wiki.centos.org/SpecialInterestGroup/AltArch/Arm32/RaspberryPi3 as it already exists
