Multiboot&Universal Installer for Odroid C1, C2 and XU3/XU4

davidwkerr · Post by **davidwkerr** » Thu Jan 04, 2018 4:23 pm

Hi All...and a big thank you to loboris for Multiboot and voodik for Lollipop, Nougat and other things.

I have been running multiboot on an XU4 with 64GB emmc plus Ubuntu 16.04 and CM12.1 (Lollipop- 5.1.1).

I am wondering how I can upgrade to (for instance) CM14? I HAVE successfully installed Nougat (loboris CM14) to an SD card but I would like to upgrade the CM12 to this on the emmc.

I really do not think that renaming the xxx.7z Nougat install files to update.zip will do anything. Taking my Nougat SD build and creating all the .img and other files so that I can make an update.zip of the correct format seems impractical.

So, how is it done? I imagine some of you have already achieved this.

I do not mind writing off the CM12.1 when installing Nougat- that is not a problem.

Puzzled,
Dave

In Android Update mode, the various update.zip files do not work for me because they are missing userdata.img and the system.img file is split into system_aa, system_ab etc and the installer does not recognise these- it wants "system.img".

Perhaps the aa, ab files can be joined to make system.img but certainly simple concatenation does not work.

Cheers,
Dave

Okay, hope this helps others. I now have Android 7.1.2 running with Ubuntu 16.04 Multiboot.

What I had to do:

1. Generate my own installation image from loboris's GitHub. It is more up to date than the prebuilt images.

2. I changed the references to "emystem" and "sdystem" to "emsystem" and "sdsystem" respectively in the install script file because the script could not mount my system install partition for Android (by name).

3. The backup and install from backup (on USB disk) work reliably (thank goodness) so I was able to do lots of testing. But in the end, I went with a straight install of voodik's CM14.1 using his update.zip. But I had to modify it (as I did all update.zips used).

4. Unzipped update.zip and concatenated the system_aa, system_ab..... files with cat system_* > system.img. Then deleted the split files. Also had to add a dummy userdata.img file else the install script will not update or indeed install. Then rezipped all the files in the directory to a new update.zip and that worked perfectly.

Regards,
Dave

Great work
Can you share your mod update.zip?
Thank you

Hi, I am happy to do that. Just need to figure out a way given the poor upload speeds in Australia.

davidwkerr · Post by **davidwkerr** » Sun Jan 07, 2018 5:31 am

Okay, here is my update.zip. I put it on my web site.

https://www.kerr.net.au/dpkerr/update.odroid

Download it, rename to update.zip, do a md5 check- it should be:

bbe66434c6e7d7e90468a78581abbde9

It is around 425MBytes in size. I advise using a USB attached disk and not a memory stick for the install due to the number of temporary files created, copied and moved. A memory stick would be very slow.

Please note that I have used this particular update.zip with the Multiboot installer INSTALL option but not tested it with the "Update Android" option.

Remember to generate a new multiboot installer before you start.

Regards,
Dave

Hi! Good evening!

At the first time, sorry about my english.

I´m new here. I´d would like about the possibility about change the size of partitions. I´ve a emmc 128 gb and I cannot use more than a 100 gb because gparted can´t do more than four partitions. I´ve used multiboot v3.

Thanks a lot!

PD: if your spanish is better than my english, please, use it

mad_ady · Post by **mad_ady** » Thu Feb 01, 2018 3:22 pm

You will need do convert a primary partition in a extended one and you can create logical partitions inside. Not sure if multiboot supports them by default though.

Thanks you very much mad_ady. I tried that, but gparted can´t let me change and do something. I´ll try to install multiboot manually, but I dont know how can i do from Windows 10.

Thanks a lot again for you answer

mad_ady · Post by **mad_ady** » Fri Feb 02, 2018 3:49 am

It should work with gparted, but you need to delete the last partition and create an extended one. Inside the extended partition you need to create one (or more) logical partitions.
If it doesn't work post back screenshots with the error message.

Thanks again. I just tried to do that but I can´t remove the last partition because is a linux partition and gparted doesn´t let me unmount the partition.
I´ve just installer ubuntu mate from hardkernel. How can I continue for install multiboot? I read the tutorial but I don´t understan so good.
Sorry, I,m new in Linux, my knowledge is basical.

Thank you very much for your interest.

mad_ady · Post by **mad_ady** » Sat Feb 03, 2018 3:02 am

You should make changes to the partitions with the emmc/sdcard connected to a different system (e.g. booted from a different disk)

@qwertyodroid, you can also use a "live CD/USB" version of gparted standalone to overcome your issue. Download an image and burm/flash to the appropriate media (DVD or USB Stick) and then boot to it on a laptop/desktop to modify or setup your partitions on the Odroid emmc or SDcard, in a USB reader. Here is a link to the gparted site where you can find a live image.

Hi All Friends here..
First of all.. big thank you to Loboris for his hard work...!!!

I have a problem .. i have an odroid c2 with an hifi shield 2 sound card..
My goal is to run at least two distro's..

Distro 1 = Libreelec Latest from raybuntu
Distro 2 = Volumio

i managed to install 3 distr.'s were only two are running.. and the third ( Libreelec ) will not boot and gives only blue light..
I have searched and searched and tried and tried.. but i am stuck..
Is there anybody who could point me to the right direction to get to my goal..
Best regards Osdieman

I finally got around to play with this. Following the instructions above..

davidwkerr wrote:Okay, hope this helps others. I now have Android 7.1.2 running with Ubuntu 16.04 Multiboot.

Created my own repo with the fix mentionied by @davidwkerr https://github.com/slayer1991/Odroid_Multiboot

I had a 8 GB EMMC and a 16 GB SDCard.

Method 1
Prerequisite for me: have a linux install on the EMMC
It seems that the 'init' script doesn't detect EMMC and SD cards properly (at least in my case). The following env vars were fine:

BOOT_CARDTYPE="SD"
OTHER_CARDTYPE="EMMC"

but these were wrong:

BOOT_CARDDEV=0
OTHER_CARDDEV=1

Once it started, press X for the bash prompt. "fdisk -l" allowed me to identify the proper number for CARDDEV under the form mmcblk<number_here_from_card_size>p1

After I swapped around the vars, the installer started properly:

BOOT_CARDDEV=1
OTHER_CARDDEV=0

Method 2
Keep just the SD card for the first install, add the EMMC after

Other notes
Can't install linux2 without linux1 (may have been mentioned on the forum)
Can't install the 2 linux installs on different cards (emmc vs sd)

Will continue to edit this post if further issues encountered and solved

I ran the command listed in the tutorial.

Code: Select all

sudo dd if=multiinstaller_XU.img of=/dev/sdb bs=1MB oflag=direct

I checked in the diskmanager and it said the disk was /dev/sdb
However, I tried flashing it to SD card with etcher of my Windows pc, which worked. At least it boots.
But as someone else said in a previous post, I also get the message "no multiboot card detected" or whatever it was. When I went for the option to install OS'es, it gave me an error that saib something about "error copying multiboot files".

I had my linux image on the first partition of my NTFS external hdd and it was renamed to linux.img. Tried connecting the external drive before booting the odroid and also tried it during, same issue.

Something useful might be that the eMMC that was installed on the board already had an OS installed. The microSD card used for the multiboot image is a sandisk U3. Oh and yeah, duh, I havent mentioned which board I have. I have the XU4.

I didn't have any luck with getting past my issues, so right now I run Recalbox.

Hello Loboris and co,

I am new to odroid.
I have an xu4 and played with multi installer.
I had installed two linux images ubuntu 16.4 and retropie (ora).
I cannot boot twice without errors.
I read almost all the scripts and why the kernel exynos xu3 is used even on a xu4 (in first boot, in linux boot and linux2 boot)?
In the first instance, my ubuntu booted but I hadn't ethernet. This problem is solved if kernel xu4 is used.
I tried to change manually this. It worked for the first boot and the init and boot files are reverted to old ones.
May be due the init file in /.
Then my question is can the author make a multiboot image done for xu4?
Thanks

Hi Tony,

had exactly the same issue. Found out that dd uses this ambiguous error also when it doesn't like the oflag. So I've removed oflag from the command and it's working now.

Code: Select all

sudo dd if=multiinstaller_XU.img of=/dev/sdb bs=1MB

Odroid c2 with the Barturblits scripts would work ok when updating ubuntu 16.04.
With ubuntu 18.04 I'm getting a error when updating the kernel, I always end with error on mounting /media/boot. Does anyone have the same issue?
I'm getting this error.

m4f2g · Post by **m4f2g** » Sun Jul 08, 2018 11:17 pm

Edit:

I Did not get behind that.... i really really tried...

use prepared multiboot installer images, in multiinstaller_C1|C2|XU.img.zip, unzip to some empty directory
->runsudo dd if=multiinstaller_C1|C2|XU.img of=/dev/sdX bs=1MB oflag=direct

if the image file is created, you can write the image to SDCard using dd command.
copy your installation sources ((..)Linux .img,) to the first partition of your USB drive
rename the Linux installation image to linux.img!

on Odroid UX4/XU3 set the boot switch to boot from SDCard
connect you USB drive to Odroid, insert SDCard and power on
select Install from menu
follow the instructions to select desired partition sizes and installation destination (SDCard or EMMC)

it is a little bit confusing... Does i need an extra usb drive (stick or hdd/ssd whatever)..?

I only have a "huge" (blue) eMMC and a 2,5" 1tb hdd via usb3.0 intended as extended home drive.. . Could borrow one from camera...

on Odroid UX4/XU3 set the boot switch to boot from SDCard

without µ-sd-card?

How should the emmC (be formatted)?
There is by default a 128MiB (fat16) primary partition on it known as mmcblk0p1.
Then on my own decision a ext4 / root for ubuntu Mate 18.04. Rest is extended... unallocated... mmcblkOp2

Where (partition) should placed multiinstallerxu.img?

use prepared multiboot installer images, in multiinstaller_XU.img.zip, unzip to some empty directory

where??? emmC {or usb hdd or other stick}?

And each other Linux of different os img?
in the next partition? should make it a differend if extended, primary or logical?

Thanks

With every new release of LibreELEC I always replaced teh files SYSTEM, KERNEL and meson64_odroidc2.dtb.oelec manually and it always worked fine.
With the latest LibreELEC 8.90.004 for Odroid-C2 (http://archive.libreelec.tv/LibreELEC-O ... 90.004.tar) this method does not work.
I get an error at boot saying /dev/system cannot be mounted.
Any advice? I suspect something needs to change in boot.ini.oelec but I am not sure what.

Hi, can anyone prepare a dual os boot image with Android latest version and Libreelec latest version(LE9, possibly sky42 build as it has hw acceleration) for me pls.
i tried to update the LE from within LE and it broke the multiboot function. I dont need Lakka and Linux as i am a very noob user.
i just want to use Android and LE as of now.
As far as the multiboot menu goes, is there a way to save the Boot menu settings which persists even after reboot ? i tried to reduce the waiting time to 10 seconds but once it reboots it sets to default 60 seconds.
I would be greatful if anyone creates a dual boot OS image for me. Thanks in advance.

I tried to install gapps, but don't work. I download some apks from apkmirror. Youtube don't work because of play services. Did anyone solve this problem?

malomehi · Post by **malomehi** » Mon Dec 10, 2018 2:49 am

Anyone who managed to update previous LibreELEC version with new 8.90 versions in Odroid-C2?
In the past it was enough to replace SYSTEM, KERNEL and meson64_odroidc2.dtb.oelec files manually but this does not work since 8.90.
It complains at boot saying /dev/system cannot be mounted.
Any solution? Re-installing Ubuntu with all my configurations could be really tedious just to have latest LibreELEC version.

EDITED: I managed to find a solution and it works. File boot.ini.oelec needs to be modified. The boot.ini file to work with can be extracted from the latest LibreELEC version and then manually modify the relevant lines to point to multiboot/KERNEL and multiboot/meson64_odroidc2.dtb.oelec. Also I needed to manually add lines to restore multiboot boot.ini file before booting to LibreELEC. Finally you replace boot.ini.oelec with your modified file.

These are the lines I have modified:

setenv bootrootfs "BOOT_IMAGE=multiboot/KERNEL boot=LABEL=emuserdata disk=LABEL=emoelec"

fatload mmc 0:1 ${kernel_addr} multiboot/KERNEL
fatload mmc 0:1 ${dtb_addr} multiboot/meson64_odroidc2.dtb.oelec

And added:

# =================================================
# = RESTORE boot.ini FOR MULTIBOOT, DO NOT CHANGE =
# =================================================
fatload mmc 0:1 0x60000000 multiboot/boot.ini.multi
fatwrite mmc 0:1 0x60000000 boot.ini ${filesize}
# =================================================

just before:

booti ${kernel_addr} - ${dtb_addr}

I also commented out this line as I think it is not needed but I might be wrong:

#if fatload mmc 0:1 ${uenv_addr} config.ini; then env import -t ${uenv_addr} $filesize; fi

Hi everyone,

I've generated the Multiboot Image v4 (for Odroid C2) with the following OS's pre-installed:

Android 6.0.1 [2019-01-17]

Ubuntu MATE 18.04 Bionic LTS [2018-06-21] (Linux in the boot menu)

LibreELEC RR 9.1 [2019.04.24] (OpenELEC in the boot menu)

Unfortunately I cannot share this image due the size of the eMMC module (32GB), at my end I can upload about 300MB in 1 hour so... this image size is about 20GB, to upload that image will take days. I'm sorry about this, however I will share some files and steps as reference to generate that image by yourself. First, LibreELEC RR? Yes, this version of LibreELEC include EmulationStation, RetroArch and Pegasus. This build will avoid to install additional images like: RetroPie, Lakka, etc. It works great. Android and Ubuntu works good as previous multiboot images.

=== This is What I did ===
To create the multiboot base image, I've used @sdip custom repo. Download the base image here. Once the download is completed, unpack it and flash it into a SD card or eMMC module. I recommend eMMC module.

=== Android ===
Download Android Daily file here. Once the download is completed, rename it to: update.tar.gz Put that file into an USB drive with a fresh single EXT4 partition format.
===============

=== Ubuntu ===
Download Ubuntu MATE 18.04 Bionic LTS here. Once the download is completed, unpack it and rename it to: linux.img Put that file into the same USB drive where Android file is.
===============

=== LibreELEC RR ===
Download LibreELEC RR v9.1 here. Once the download is completed, rename it to: oelec.tar Put that file into the same USB drive where Android and Ubuntu files are.
===============

This is it, put the SD card or the eMMC module and plug the USB drive (where Android, Linux and LibreELEC are) on your Odroid C2 device and turn it on.

1. In the multiboot main screen press I (Prepare the card for MultiBoot, Install OS's).

2. Change partitions sizes as you wish.

3. Once again, press I to start the installation.

4. When this process is completed, reboot the device.

From this point you will be able to boot Android & Ubuntu without any extra step. Now, to boot LibreELEC RR you need to follow these steps from (and thanks to) @malomehi. As reference, I'll share my current multiboot directory (from an eMMC module) here in case you want to compare files at your end. Be aware that if you compare my boot files (I use a eMMC module) with a SD card at your end, you have to change partitions labels, example: emuserdata (eMMC module) to sduserdata (SD card). Also, in my boot files I've set up a 1360x768p60hz resolution, you may need to change it at your end. Let me know if you find any issue before, during or after the installation process. I'll take a look.

Known Issue: after Ubuntu full upgrade (apt upgrade -y; apt dist-upgrade -y) these files: Image, meson64_odroidc2.dtb and uInitrd are updated out the multiboot directory, all you have to do is add .linux in these files names (example: Image.linux) and move them to the multiboot directory (overwrite them).

Note: I've plans to get a couple of new eMMC modules (8GB and 16GB) plus an USB 3.0 eMMC Module Writer, with this I'll be able to share more custom multiboot images.
UPDATE 2019.10.23: I have new eMMC modules (8GB and 16GB) and the USB 3.0 eMMC Module Writer, courtesy of Hardkernel. Thank you so much. I'll be back with more multiboot images very soon.

Many thanks to: @loboris, @odroid, @dimitris_c, @barturblits, @luffyman, @sdip and @malomehi for making this possible.

Hi everyone,

I've generated the Multiboot Image v4 with the following OS's pre-installed:
Android 6.0.1 [2019-01-17]

Ubuntu MATE 18.04 Bionic LTS [2018-06-21] (Linux in the boot menu)

LibreELEC RR 9.1 [2019.04.24] (OpenELEC in the boot menu)
.....

Sorry for that newb queastion but, i tried ( android LINUX AND OLEC) at EXT4 formated usb or NTFS, and it not reconized.
I click "i" for prepare sdcard and it not works, timer countdown goes to 60 again and no way to start configuration.

I tested it with 2 different usbs and no results.

There are any other way to try it?

Best Regards

That sounds like something's wrong on the partition format. Try to give the EXT4 partition format on your USB drive with: GParted on Linux or Mini Partition Tool on Windows

Let me know if that fix the issue.

Hi everyone

I have question especially for alexxgg

Can You tell me how to prepare or prepare multiboot image with Android, LibreELEC and Volumio ?

I tried out Multiboot Image v4 from alexxgg but i manage install only Androin and LibreELEC.

Hi everyone,
I've generated the Multiboot Image v4 (for Odroid C2) with the following OS's pre-installed:

LibreELEC RR 9.1 [2019.04.24] (OpenELEC in the boot menu)
Unfortunately I cannot share this image due the size of the eMMC module (32GB), at my end I can upload about 300MB in 1 hour so... this image size is about 20GB, to upload that image will take days. I'm sorry about this, however I will share some files and steps as reference to generate that image by yourself. First, LibreELEC RR?

Hi everybody.

Does anyone tried to multiboot on the XU4 ?

I tried the installation with different OS but everytime Android or LineageOS was never installed... The installer shows that the update.zip is uncompressed but not installed... Who has success with receent version of android ?

radudorurus · Post by **radudorurus** » Mon Jun 22, 2020 3:05 am

I am trying to use this method exactly as described.
It does not work.
Maybe there are some details missing from the tutorial.

The os images were on a 16GB card in a reader.
The card was prepared EXT4 with the odroidC2 itself.
Pressing "I" does nothing. It needs long press or SHIFT+i in order to work
Pressing I goes in a scanning with result: no instalation drive found.

How to enter in the partitioning operation of the card?
Should the card be already prepared prior to the start of instalation like in the image?
The tutorial says one press "I" will lead in to the preparation/partitioning of the card. Another "I" press leads to the instalation of the chosen OS.

Hi again.
I managed to start the multiboot install process.
But the installation returns some errors (It seems the partitions are readonly or the paths does not fit).
The card is a Samsung 64GB.

I can boot to Android immediately after install ends but there is no way to reboot.
The partitions looks ok.
The boot.ini seems corrupted.
Here is the log file.

Can anybody give a little help please?

Sorry, I doubt many are still using this multiboot method. It worked, but involved moving some files around, and could easily break. If only tobetter could clone himself to work on petitboot for c1/c2...

That would be more elegant...

Since the universal installer is no go for me, I opted to try again the multiboot image v.3 with Android6, Ubuntu16, Libreelec, Lakka.

The image is 16GB but my card is 64GB. I tried this image in the past on a 32GB card. I had no way to exted the partitions to fill the entire available space.
I used another Ubuntu 18 installation card on OdroidC2 for working with the partitions on the 64GB multiboot card.
I did resize and move for the partitions in the extended section. No problems for booting all 4 OSes.
I encountered problem on resizing the extended partition to make more room for the boot, android and cache partitions.

Now I have a Lubuntu installed on a P4 HT machine dual boot and it seems it works moving the beginning of the extended partition. I hadn't time to check if it works.
I hope the boot process was not affected and it will work as previously.

Sadly the multiboot feature hasn't seen any love in the past years... I think the original instructions need adjusting to make it work with current OSes for xu4.

I'm a stranger to Linux.can a friend who uses xu4 also help if it works multiboot right now?
