Hello,
I don't know if this is a dev issue/problem, but I bought 2 RPI 3 about a year ago, and installed centos on one (the other one I haven't even used yet).
It seems the Mac address changes every reboot? (into something 'random', because the first 2 numbers indicate the manufacturer, right?
Is this a known issue? is it an OS or hardware issue?
thanks,
Ron

Something I discovered when we were looking at WiFi support for the RPI3 : there is one file "controlling" the needed firmware for it : /usr/lib/firmware/brcm/brcmfmac43430-sdio.txt
If you look at that file, we decided to comment the macaddress line, to avoid all the provisioned RPI3 boards to suddenly uses the same static mac address everywhere. So the file (as present in the rpi image we provided) is looking like this : #macaddr=00:90:4c:c5:12:38
That can probably explain what you're seeing ?
Hello Fabian,
I'll look at that one, there also seems to be a confix.txt in /boot, that the RPI uses for several things.
What I noticed though, is that if there's no cfg script in network-scripts for the device (ifcfg-wlan0), after NetworkManager starts, the Mac addr seems to be random. (while on other Centos/RHEL/etc machines I have, in that case the Mac address/device would just not show.
When that script is there, NetworkManager consistenly shows the correct Mac (which depends on the serial of the board, I read somewhere)
thanks,
Ron

Actually, what I found out is that if something is wrong with the configuration, NetworkManager doesn't seem to work correctly and give a random MAC address.
Now I am trying to get Bluetooth to work, looks like I can't even see the device?
What is the latest version of Centos? and is there still work being done on a 64 bit version?
thanks,
Ron
