[fedora-arm] Summary of Fedora on Odroid XU4
Summary of Fedora on Odroid XU4
1. with Kernel 4.6.5-300.fc24 system boots without failure, but update
to newer kernel fails due dracut didn't build suitable intramfs
https://bugzilla.redhat.com/show_bug.cgi?id=1482825
2. newer kernel works only with "cpuidle.off=1" inserted into the
"append" kernel line in the /boot/extlinux/extlinux.conf file, but all
USB3 Hosts failed, no onboard ethernet
3. To boot the system from the eMMC card:
A. The initramfs image file must be rebuilt. The simplest way is to:
a. Boot up using the MicroSD card;
b. Partition the eMMC card such that partition 1 begins on sector
3072
(Default starting sector from fdisk is 2048). There should be
4 partitions created;
c. Mount the Fedora image desired to be installed on the eMMC
card;
d. Copy all partition data from the mounted fedora image
partitions (there are 4 for Fedora 26 ARM images) to the appropriate
eMMC partitions;
e. Update the UUID values on what will be the
/boot/extlinux/extlinux.conf file and /etc/fstab files of the eMMC card;
f. Assuming the eMMC partitions are mounted as such --
mount /dev/mmcblk1p4 /mnt
mount /dev/mmcblk1p2 /mnt/boot
then perform the following mounts --
mount -o bind /proc /mnt/proc
mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys
B. Rebuild the eMMC card's initramfs by executing the following
command:
chroot /mnt dracut --add-drivers='pwrseq_emmc mmc_block'
/boot/initramfs-4.11.8-300.fc26.armv7hl.img 4.11.8-300.fc26.armv7hl
C. Flash the boot information in the header of the eMMC card;
C. Shutdown the system, then remove the MicroSD card;
D. Boot up using the eMMC card.
4. If the system is to be updated using "dnf update", a new initramfs
image must again be generated. This can be done using steps 1f - B.
above using the new initramfs and kernel images provided by the "dnf
update".
----------------------------------------------------------------
Note to the developers/maintainers of dracut:
The kernel modules "pwrseq_emmc" and "mmc_block" should be included in
dracut for the Odroid-XU3 and Odroid-XU4 such that the user need not
have to execute this procedure each time and update to the system is
performed.
Is this correct and complete ?
