I installed Armbian_5.33_Odroidxu4_Debian_jessie_next_4.9.37.img for odroid XU4, then I used this script trying to install latest kernel with mali support. Since the preinstalled one 4.9.37-odroidxu4 didn't have support for it. I run your script and those are the last lines I got:

Install kernel
mount: mount point /media/boot does not exist
mount: mount point /media/boot does not exist
sed: can't read /media/boot/boot.ini: Not a directory
Using dtb: exynos5422-odroidxu4.dtb
cp: failed to access ‘/media/boot/uInitrd’: Not a directory
umount: /media/boot: not mounted

Kernel updated successfully
Reboot to use new kernel

I wasn't cautious and didn't see about /media/boot does not exists and some failures... only Kernel updates successfully which was false since then I was in a loop and now I have to reinstall it :)

What exactly is "/media/boot"? Do I have to create it manually or is this on openmediavault3 named something else?

Thank you!

Second try:

I've created /media/boot and run update script:

./update-kernel.sh

Extract kernel

Kernel Version: 4.9.38

Copy firmware and modules

Create intramfs and uInitrd
update-initramfs: Generating /boot/initrd.img-4.9.38
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
W: mdadm: no arrays defined in configuration file.
update-initramfs: Converting to u-boot format

Entry Point:  00000000

Install kernel
mount: special device /dev/mmcblk0p1 does not exist
sed: can't read /media/boot/boot.ini: No such file or directory
Using dtb: exynos5422-odroidxu4.dtb

Kernel updated successfully
Reboot to use new kernel

So this time only these 2 commands failed:

  1. mount: special device /dev/mmcblk0p1 does not exist - but I think that's normal since I also have /dev/mmcblk1p1
  2. sed: can't read /media/boot/boot.ini: No such file or directory - no idea why /media/boot/boot.ini is not present?

Any help appreciated.

Hi,

yes unfortunately OMV3/armbian changed the boot layout so this script is not compatible with OMV3 right now.

frojnd commented Aug 25, 2017

Will you update the script for OMV3 in the near future? Just askin.
