Re: [CentOS-devel] Help needed to Install CentOS on Zynq ZC706 ARM cortex A9
by Piyush Jadhav 14 May '19

No worries, I hope to understand the SPL boot properly though. I will go through some reading and in any case, I will wait when you can look into it. For now, *I managed to boot centOS* using the kernel made with petalinux/yocto, and yes I had problems with rights and properly copying all the files. You have been a great help and thank you for that!

CentOS 8.0.1905 build status
by Fabian Arrotin 14 May '19

14 May '19

Hi, As everybody is probably aware now, RHEL 8.0 was released earlier this week . Instead of publishing multiple blog posts here and then point to updated content, we decided this time to have a dedicated wiki page that can be used to track our current status : https://wiki.centos.org/About/Building_8 So now you can look at that page while we're busy on those tasks, and refresh from time to time. Let's spread the news about the wiki page and point people (on mailing-lists, irc, forums, etc) to that page to get all latest news about CentOS 8.0.1905 build status ! Cheers ! -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

Preliminary RHEL 8 review
by Nico Kadel-Garcia 14 May '19

14 May '19

I've noticed a few things that may help other people setting up test environments. 1) The RPMs on the installation media are split into two distinct repositories, "BaseOS" and "AppStream", for no reason I can discern. This means that if you try, like me, to mount a DVD image and use it as local yum repo for testing out kickstart setups and mock builds, you need to address the multiple necessary repositories with the new names. 2) For Virtualbox, it absolutely needs more than 1 GB of RAM.With only 1 GB, it hands during hte firstboot setups. 3) Mock is going to be.... awkward to port, due to multiple python dependencies in on the DVD.

Hi Pablo, Sorry for the late reply and thank you for pushing us for getting the serial port repaired, the port was not functioning. Now that we have it working, I have started to debug through the serial communication, but I want to raise some doubts in the process. In the blog, https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp, the last step is to *dd* the *u-boot-with-spl.bin* file as follows, > dd if=/usr/share/uboot/${boardmodel}/u-boot-sunxi-with-spl.bin of=${sdcard} bs=1024 seek=8 conv=fsync,notrunc > > But is missing how to load the *u-boot-spl.bin *and* u-boot.img. *Could you please shine some light on this for us? I understand that the order has to be ROM code -> SPL -> u-boot -> kernel. Does it means that I have to also dd u-boot.img, like here, > dd if=u-boot-spl.bin of=/dev/sdX bs=1024 seek=8 > dd if=u-boot.img of=/dev/sdX bs=1024 seek=*X (?)* > > On the other hand, I also tried to boot with another method using only the centOS Rootfs file (in the root ext4 partition), and the Boot.bin and image.ub files (in boot partitions) which I created using petalinux/yocto. The kernel boots up but falls into the kernel panic, with errors as *cant execute the /sbin/init - (error -8)* -> which refers as permission denied. Please let us know what you think of this too! Thanks a ton in advance!

Installing kernel 4.14.34 through kickstart
by Far Had 06 May '19

06 May '19

Hi, Trying to compile and put kernel 4.14.34 into the CentOS 7 (1511 release) DVD with a ks.cfg already configured. This ks DVD has been working fine with the original 3.10 kernel. Here is what I did: I built rpm packages of the 4.14.34 kernel with disabled kernel debugging option. This gave me 3 rpm files: kernel, kernel-header and kernel devel. I replaced them with their equivalents in isolinux/packages directory in the DVD ISO image and made a new ISO file out of it. when booting from this image, automatic installation fails after installing all packages in the post installation at "generating initramfs" phase. The exact error text is: "No such file or directory" (image attached) Regards.
