You'll have to run dracut yourself to build one, as far as I am aware, I'm used to a raspi which needs to use binary firmware, and the generic kernel doesn't work as well as the one compiled by the raspi foundation
cc35359, Running dracut manually did the trick. I am able to use CentOS7 stock kernel on my Cubietruck3.
Gordan, I am using the kernel that is available in the CentOS Repo vmlinuz-4.0.0-1.el7.armv7hl
Ok, so the next task I created a disk image using dd and installed @core and kernel. This works on the Cubietruck3. I tried to boot the same image with qemu using this script http://pwhalen.fedorapeople.org/Fedora/20/boot-vexpress . I got the CentOS login prompt using the F22 kernel and initramfs. http://pastebin.com/mHBazwU4
The CentOS kernel and initramfs however is not able to find the root partition . It waits forever, gets stuck here http://pastebin.com/EUeBvcKD
Does anyone have a working CentOS initramfs and kernel for qemu?
