Hi,
Kernel 4.18.x brings nice features, CPUFreq for Allwinner H3 SOC's being among them.
Therefore I had a go on updating to the community-kernel-latest version 4.18.14-200.el7 which failed; Dracut could not (re)build a intitramfs-4.18.14-.. and (probably because of this) uInitrd-4.18.14-.. was missing to. Unfortunately did not write the exact error message down; next time will do so.
BTW: Update to Kernel 4.17.17-200.el7 was successful on my oragngepi-plus2e
In my own interest i'd really want to help to debug this; but to be able to do this i need to understand in more detail how we boot Centos on our u-boot based SBC's. I got the broad picture: u-boot >> extlinux bootloader >> kernel >> Getting lost however looking at extlinux/extlinux.conf , grub/grub.conf and not knowing the content of boot.scr
Can somebody enlighten me on this, or show me some further reading.
(I did search fedora's arm documentation without getting smarter..)
