Following a thread started last week, I built some images for the new rpi3b+ model, as it needed a newer firmware/kernel anyway.
So here they are : - https://buildlogs.centos.org/rolling/7/isos/armhfp/CentOS-Userland-7-armv7hl... (console only) - https://buildlogs.centos.org/rolling/7/isos/armhfp/CentOS-Userland-7-armv7hl... (gui with gnome3)
Those images support the rpi3b+ model OOTB , including with WiFi
Cheers,
