[fedora-arm] Re: Raspberry Pi 3 B+ dmesg errors

Hi Felix,

Sorry for the late delay, some how this message hit my spam box.

> I managed to get Fedora 30 AARCH64 installed on a RPI 3B+ and it mostly runs great but I'm hitting a couple issues that I'm just not sure where to start looking.

> In order to make sure it's not the set of packages I'm installing, I brought up a second RPI 3B+ that runs the official minimal image. I installed all the same packages on the kicked system, that the minimal version has, so I don't have differences.

What doe you mean by "official minimal image"? Do you mean Fedora or Rasbian?

Most of those can be ignored. In part it might depend on the answer to
the question above.

That message comes from the DT if it's provided by the firmware, which
would also explain some of the differences above.

Is there a kernel version difference?

> 5. There is a couple more differences like hci initialization and other things. Isn't this part of the kernel support? And the kernel is the same on both systems.

What does "uname -a" report? I suspect the difference here is the use
of the firmware provided DT vs kernel provided.

Do you have a symlink if you do a "ls -al /boot/dtb/" in both systems?

> Is there documentation around the generation of the RPI image? I replicated the kickstart file that can be found under /root on the minimal image but that alone didn't help above issues. Maybe there is something special about the environment this image is generated in?
