Right, so copied the contents of folder target and also the contents of folder3rdparty\bootloader to the root of the new system partition.
Believe I've got it right.
File list

Code:

folder: overlays
bcm2709-rpi-2-b.dtb
bootcode.bin
config.txt
fixup.dat
KERNEL
KERNEL.md5
LICENCE.broadcom
start.elf
SYSTEM
SYSTEM.md5

But I only get the full-screen rainbow (not the low-voltage square in the corner).

Ok, what did I do wrong.

[popcornmix]

You need to rename KERNEL to kernel.img. You can remove the *.md5 files.

[vbat99]

Well, success, almost.
Booting then halts with
Error in mount flash: mount point: unknown file system.

Maybe I'll still with stock openelec partition sized. I'll still be able to test these builds, but was hoping to be able to test debug builds if needed to in the future.

Thanks Popcornmix and Milhouse.

Is it possible to write the .img file to sdcard then use gparted to move the partitions around?

[Milhouse]

Apologies vbat99 for not being entirely clear on that final step, this used to be a regular thing that OpenELEC users would have to do (extracting the files from the tar) and I forget it's no longer obvious to new users!

Well, success, almost.

I didn't see a cmdline.txt in your previous list of files, by default it should be:

Code:

boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 quiet ssh

See if adding the above as cmdline.txt in the FAT partition makes any difference.

You should have the following files and directories in the FAT partition on an RPi2 installation (date/times and file sizes may vary):

Code:

rpi22:~ # ls -la /flash

Yep, believe I was missing the cmdline.txt. file. That file was not in the tar downloaded from Openelec.

I'll do it over bit later today.
Been testing 5.0.8 stable, and I'm impressed with the speed and performance on the rbpi 2.

Note: If you are using the sdhost driver and experience a problem booting with the #0626 build, particularly on Pi1, you should temporarily disable the sdhost driver (ie. revert to the stock mmc driver by commenting out the dtoverlay=sdhost entry in config.txt), or alternatively disable all arm/core/gpu/v3d overclocks until the issue is resolved.

If anyone uses a mouse (does anyone?)
then please test latest build. Mouse movement should no longer cause whole GUI to redraw so should result in lower CPU and less lagginess.

Just giving Milhouse's instructions another go, and when I do the parted commands, setting the partition sizes, I get

Warning: The resulting partition is not properly aligned for best performance

I'm ignoring this so I can keep going, but is it something I should be concerned with?

[vbat99]

Second attempt, and it got stuck on initial Openelec screen, with Official Version 5.0.8.

After 5 minutes, figured it wasn't going to do anything and about to give up, but decided one last power up, and Bingo, booted to Kodi 14.2.

Unfortunately two other attempts to power up got stuck at the Official Version 5.0.8 screen, so deciding to give up.
Win32Disk Image the official and boots every time.

For now, I'll stick with this, and soon will update to Milhouse's test builds.
Thanks again for the info, I'll note it for another time to experiment with.

Cheers and keep up the great work.

Warning: The resulting partition is not properly aligned for best performance

I'm ignoring this so I can keep going, but is it something I should be concerned with?

I've amended my original instructions to correctly align the first partition, I've also added a couple of checks which will confirm if both partitions are correctly aligned.

[vbat99]

Thanks Milhouse. I've noted the changes for my notes. Will try again a bit later.
Just an FYI, probably the version of XBMC I was using to get a Linux command-line, but I could type
DISK="/dev/sdb"
but when I typed
PART1="$(DISK)1"
gave me DISK could not be found.

Guessing that is because /dev/sdb was not mounted?

Anyway, I just carefully typed /dev/sdb and /dev/sdb1 etc, double-clecking my typing as I went.

Yes, the new sdcard was at sdb, sdb1 & sdb2

[Milhouse]

PART1="$(DISK)1"

Best to copy & paste than re-type - you've used parentheses (round brackets) when the command is using curly braces (they look similar, but very different in this context!)
