[Release] Lakka + KODI Dual Boot Images for Raspberry Pi

I don’t think so…

But, NOOBS can be setup to always boot into an OS. Just have it always boot into KODI (default) Then once in KODI, boot into Lakka as normal.

Thank you, mattrix. You are my hero! This is exactly what I wanted to do with my Raspi 3.

is there a version with the latest lakka included?

mattrix · 18 August 2017 20:35

This simply uses NOOBS / PINN which will automatically use the latest stable version (currently 2.0).

Then you can easily update to RC builds if you like

still working like a charm in 2018. my raspi3 b+ switches from kodi to lakka in 20 seconds. and Lakka -> Kodi in 27 seconds.

thanks man!

Hi @mattrix,

I used your NOOBS Companion addon so far for my Raspi 3 and of course it’s a great addition

Now I replaced the Pi with an Odroid C2, where multi boot is not as simple as with NOOBS. If you are interested, there is my thread about it: Odroid C2: Dual Boot CoreELEC (eMMC) and Lakka (SD)

I just want to ask you about the Boot-Back, that gets installed on the Pi to Lakka. Can I do something similar for my Odroid. It should remove the file /storage/roms/COREELEC/boot.ini and then it should copy the file /storage/roms/COREELEC/boot.ini.elec to /storage/roms/COREELEC/boot.ini

That should be triggered, when I hit the “Quit Retroarch” in the Lakka gui, as you did with your NOOBS Companion. What is the easiest way to set this up?

Many thanks in advance! Stefan

Hi @steff,

Something like the below should work (havn’t tested)

/storage/swap_boot.sh

#!/bin/bash
rm -r /storage/roms/COREELEC/boot.ini
cp /storage/roms/COREELEC/boot.ini.elec /storage/roms/COREELEC/boot.ini
reboot

/storage/.config/system.d/retroarch.service.d/10-kodi-boot-back.conf

[Service]
Restart=on-failure
ExecStopPost=/bin/bash -c '[ $SERVICE_RESULT = "success" ] && /storage/swap_boot.sh'

You may need to restart for the service drop-in to take affect.

Based on what my NOOBS Companion Add-on does:

github.com

matthuisman/plugin.program.noobs.companion/blob/master/resources/lib/install.py#L141


finally:
    util.partition_umount(partitions[1])


## Remove kodi at startup config ##
try:
    dst = util.partition_mount(partitions[2], 'rw')
    util.cmd("(sed '{0}' -i -e 's|kodi.atstartup.*|kodi.atstartup=0|' || true)".format(os.path.join(dst, 'system', 'recalbox.conf')))
except: pass
finally: util.partition_umount(partitions[2])


def lakka(partitions):
try:
    dst = util.partition_mount(partitions[1], 'rw')


    content = """[Service]
Restart=on-failure
ExecStopPost=/bin/bash -c '[ $SERVICE_RESULT = "success" ] && reboot {0}'
""".format(util.my_partition_number())


    file_path = os.path.join(dst, '.config', 'system.d', 'retroarch.service.d', '10-kodi-boot-back.conf')
    util.cmd("mkdir -p '{0}'".format(os.path.dirname(file_path)))

@mattrix It works very well. Now my dual boot is complete

Shockwave · 18 July 2018 04:26

Just curious, got any of those images for an Odroid XU4 with eMMC built in?

steff · 19 July 2018 10:23

@Shockwave There is nothing ready to use for Odroid, which meets my requirements, so I decided to go the boot.ini-switching-way. You can find some ready to use berryboot-images for the C2 here https://berryboot.alexgoldcheidt.com/odroid-c2/ , but not for the XU4

Shockwave · 19 July 2018 13:14

It’s all good, no worries, i was merely curious, I don’t have a C2, just XU4s handy.

Hamdat1337 · 3 February 2019 01:11

I want to dualboot Raspbian and Lakka. Does this method apply?

Shockwave · 3 February 2019 02:09

In the case of that, just use NOOBS, Lakka is part of that package as well as Raspbian, Raspbian Lite, Recalbox, Lakka, OSMC and LibreElec.

Hamdat1337 · 3 February 2019 03:45

I tried it, but when I set the default OS to run be Lakka, I suddenly lose access to Raspbian. Was I supposed to set Raspbian as the default OS, but then what about starting Lakka?

I used PINN which is an enhanced version of NOOBS.

Shockwave · 3 February 2019 15:35

PINN literally stands for Pinn Is Not NOOBS! PINN usually will boot into your default OS first and not give you the option to boot out of the other one. I do believe you have to “exit” instead of power down, but don’t quote me on that one.

mattrix · 3 February 2019 20:30

In PINN you can set a “sticky” boot. That will default to boot, but you can also switch when it’s booting.

My KODI add-on is what does the “boot-back” stuff, so if your not using that, you would need to do it all manually.

You can see what it does for each os here:

github.com

matthuisman/plugin.program.noobs.companion/blob/master/resources/lib/install.py

import os, shutil, re
from xml.dom.minidom import parseString

from . import util
from . import config

def retropie(partitions):
    try:
        dst = util.partition_mount(partitions[1], 'rw')

        path = os.path.join(dst, 'home', 'pi', 'RetroPie', 'roms', 'kodi')
        util.cmd("mkdir -p '{0}'".format(path))

        content = """#!/bin/sh
sudo su -c '(echo {0} > /sys/module/bcm270?/parameters/reboot_part && reboot) || reboot {0}'""".format(util.my_partition_number())

        util.write_file(os.path.join(path, 'kodi.sh'), content)
        util.cmd("chmod +x '{0}' && chown -R 1000:1000 '{1}'".format(os.path.join(path, 'kodi.sh'), path))

        with open(os.path.join(dst, 'etc', 'emulationstation', 'es_systems.cfg')) as f:

This file has been truncated. show original

You’d want to copy the raspbian method and Lakka method to set them to boot to each other. You’d also need to figure out your correct partition numbers. If your running two OS’s, then one partition should be 6 and the other will either be 8 or 9.
