Gigabyte MP30-AR0
by Gordan Bobic 12 Nov '19

12 Nov '19

Hi, I am toying with the idea of getting a Gigabyte MP30-AR0 board (despite the insanely exorbitant price tag). Has anyone got the aarch64 CentOS working on one of those? Any special instructions? Also, if I get the ISO, is it bootable on aarch64? Does the installer work? Or does the image have to be used like on 32-bit ARM? Thanks. Gordan

Kernel problems on APM X-Gene
by Gordan Bobic 29 Jan '18

29 Jan '18

Apologies for taking so long to return to this thread, it took way longer than expected to get to the machine and get it up and running again. I also just updated the build to the latest 4.9.60. Here is a download link to both binaries and src.rpm (download the kernel tarball from kernel.org manually to build from src.rpm): http://ftp.redsleeve.org/pub/misc/kernel/aarch64/RPMS/ http://ftp.redsleeve.org/pub/misc/kernel/aarch64/SRPMS/ To recap - I am also running with Tianocore EFI chain-loaded from u-boot, and mainling 4.9.x boots just fine on it. No need for disabling ACPI on the kernel command line, no need to run EFI firmware as a 1st stage boot loader, it just works. Do feel free to try it - if that works for you but the distro supplied 4.5.x kernel doesn't, it seems reasonably conclusive that it is the CentOS kernel that is broken for this board. I'd also be interested in learning whether you have any luck getting PCIe cards to work with it without problems - I haven't tried it since upgrading to 4.9.x, but certainly on 4.4.x mainline the machine used to reliably lock up as soon as the driver for the PCIe card loads.

CentOS 7 on Raspberry Pi 3 with motion and the Pi Camera module
by Philip Taylor 01 Jan '18

Hi, I’m new to this list so I hope this isn’t a repeated question, but my searches haven’t found any matches. I’m trying to use CentOS 7 on a Raspberry Pi 3 with motion and the Raspberry Pi camera module. Has anyone done this successfully, or is it not a supported configuration? Thank you. Philip.

> > BTW, we never had any image for rpi2/rpi3 that was using the > kernel-generic repo Ok, the values are set in /etc/yum/vars. [root@dc03 vars]# ll total 12 -rw-r--r--. 1 root root 6 Dec 5 2016 infra -rw-r--r--. 1 root root 8 Oct 31 10:00 kvariant -rw-r--r--. 1 root root 2 Sep 1 07:02 releasever Seems that the "kvariant" was last modified end of october, probably by some update or other. I'ver reset it to 'rpi2' and hoping for the best. -- Kv, Kristján Valur Jónsson, RVX

I installed in in mid july when I saw it, and downloaded from here http://mirror.centos.org/altarch/7/isos/armhfp/. Something must have gotten screwed up, the CentOS-armhpf-kernel.repo is dated from sept 1st. I'll just swap the baseurl around, update and hope for the best :) -- Kv, Kristján Valur Jónsson, RVX

kernel-generic vs kernel-rpi2

Hi there. I have two Rpi3s running Centos7 but one from a few months ago. I just ntocied that the kernel repos are different. the older one has a baseurl ending in kernel-generic, while the new one ends with kernel-rpi2. Which one is correct? I notice that they are not updating to the same kernel versions. -- Kv, Kristján Valur Jónsson, RVX
