I guess CentOS 8 does not work with Raspberry Pi's.

Please take the image down if you are not going to fix it.

Hi,
Retrieved file: /dtb-4.19.72-300.el8.arm7hl/bcm2711-rpi-4-b.dtb
Skipping CentOS-Userland-8-armv7hl-generic-GNOME-1999 (4.19.72-300.el8.armv7hl) for failure retrieving fat
SCRIPT FAILED: continuing
Card did not respond to voltage select!
I guess pin configuration of device tree for mmc would be different from uboot. so, it would be failure to access mmc after retrieve bcm2711-rpi-4-b.dtb.

What does this mean? Do you need to rebuild the image?

Yes, I think so. as your log, you can use mmc in the uboot but, it could be disable by reconfiguration by accessing and config hw again in the kernel. so, in general, pin-mapping in the dts file for the mmc (or other devices you will use) should be the same as it kernel use.

As your log, mmc port using in the uboot could be reconfigure to other purpose, I am not sure what it is now.

Or, power management unit would be different from what uboot use or different from pin mapping controlling power device I guess.

If this image works in the RP 3 or other version, you will compare with HW changes in the RP 4 and can apply it to device tree script in the kernel.

There are apparently no rpi4 ready CentOS 8 images as yet. The ones on the mirrors are for previous models only.

Then why did you tell me this was for Raspberry PI 4 in my original post? I guess you were not aware this was not for the PI 4?

Correct. I was involved in testing various images on my rpi4 during the creation of CentOS 8 and they all worked perfectly for my needs. I also tested those same images on previous rpi models and they worked on those too so I made the assumption that those had made their way into the published images hence the lack of a '-4' image like the CentOS 7 ones. As it turns out, there is no support for rpi4 as yet and these images only work for the older ones. I'm not sure what the hold up is but the images I tested were command line only so it's most likely GUI problems.

We made a test version for rpi-4/aarch64 and it is here https://people.centos.org/pgreco/CentOS ... Minimal-4/

Hopefully we'll have it ready for 8.2. Please notice that the image is the normal userspace but the kernel and the image were created by me, so don't use it if you don't trust me :D :D

Thanks a lot. Your image works great with my raspi 4.
Only thing I noticed: /bin/rootfs-expand is missing.
