128mb MicroSD OpenELEC Question

Fri Jul 25, 2014 9:39 pm

I have a 128mb MicroSD card so I had a question about OpenELEC,
Can OpenElEC be put on a 128mb MicroSD card?

Does it need to be a specific version?
I know that the GPU needs 128mb as well as I am sure that will come up.

Thanks in advance for your help.

Which bottom of which drawer full of old junk did you find that tiny SDCard in? Or is it 128GB and you've misread the label?

Openelec is a 108MB download but you won't have any free space for media files on a card that small.

GPU needs 128mb = that is related to the on-board memory not the SD Card

They are new MicroSD cards and are 128mb not GB and yes I am probably a bit crazy.
BerryBoot V2 fits onto the card but with only 8mb left over it can not even run the 0mb MemTest, which is weird, but I can boot from USB and soon hopefully my network, :D .

The goal is to boot off a NAS or Server.
For now I am seeing what else is possible with these tiny MicroSD cards.
When you are using more than 2 or 3 Pi you start to look at easier ways to handle the OS.
Also as a teacher on the forum said having one standardized server based system reduces your headaches as 2 kids per class won't be saying, 'hey my card or USB Memory Stick is not working', d'oh!!!

Is there a 128MB OpenELEC image that is already built I could try?
Is there a way to build an image on a larger memory chip, shrink the partition, and create a 128mb image as that is the actual image size?

Thanks again for your help with this.

If you wish to use the Pi as a Thin Client, then that is feasible, a starting point is looking at these projects

Thanks for putting the links on this thread. I had read about one of the projects but not both.
So the goal of this thread is a working 128mb OpenELEC bootable SD card, any suggestions and is it even possible?
For Media I am planning on a USB hard drive or USB Memory Stick with music, pictures, and video. I may also use it on my network.

If this works it lowers my cost from about $45 - $50 for a Media Center Pi with a descent 8 or 16gb card and good power supply to $37. I tested the .99 power supply on the B+ over the weekend and it took 3 hours of pictures with no failures. My 128mb MicroSD cards were .99 too. I know you still need HDMI, Micro USB, and possibly network cables too.

Thanks again everyone.

That would be a good test to put a temperature sensor on it and run a Pi with it for a month.
The fact that it worked is the main point. It took a few tries to get a power supply for my model B and camera.

To clarify, as the developer of RaspberryPi-LTSP, RaspberryPi-LTSP only supports Raspbian. It is basically hard coded in as it builds Raspbian on setup from all the packages.
Once could though put whatever packages from the Raspbian repo over the top of the Raspbian install.
RaspberryPi-LTSP requires only roughly 27mb of files on the SD card, although you need another machine running Ubuntu on the same network to run host the server. Plus you required Ethernet between the 2 (via a switch or hub of course).

Berryboot is just a frontend to the same system, LTSP, so again it all depends what you can build on the LTSP server.

I would highly recommend if you are just going down this route because you don't want to buy a bigger card... Buy a bigger card... LTSP is no easy beast to tame, especially on its own (RaspberryPi-LTSP makes it a lot simpler).

Thank you very much for the information on setting up LTSP.

The original goal of this thread was OpenELEC on a 128mb card.
Use of a network boot was for the multi headed hydra I am working on with 10+ Pi's.
Ideally I could boot from a single NAS and as an alternative I will boot and use the NAS for 'transfer' storage. The Pi holds the data then transfers when it can to the NAS. This seems like the simpilist idea for me.
Any suggestions on creating a 128mb OpenELEC bootable MicroSD card?

Raspbmc may be easier as it is based of Raspbian ??

I am sure that by digging deep into Linux you could work it out, because you appear to be the only one who wants to save $5.00 by not buying a bigger SD Card:

Wow I love this thread as I am asking to learn and see what is possible and the answer multiple times is, cheap guy pay more $$$. This was not about saving $$$, it was about learning and pushing the envelope.
So I guess this is now my challenge to make a Media Center on 128Mb card.
I was leaning towards OpenELEC as I read an older version fit on a 128mb card.
This works out better for me as I needs to learns me some mores, engliz police pounce now.

The /flash partition of openelec requires less than 126MB so this is very straightforward if you use a USB drive for the /storage partition. Just format the SD as fat32 and copy the following files to it from the openelec tar download:

target/KERNEL (copy to kernel.img)
target/SYSTEM
3rdparty/bootloader/*

then edit cmdline.txt, replacing disk=/dev/mmcblk0p1 with disk=/dev/sda1

(or better still, get the UUID of you USB drive and use that as disk=UUID=<whatever>)

I have done this before to boot from USB, love the UUID.
Can the OS be fully booted from the 128mb card? Meaning without the additional USB device?
I currently use BerryBoot on a 128mb card and I can put OpenELEC and other OS's on the USB drive.

Is there something the OpenELEC OS needs that will require more space than 128mb?
I know I will need 'media' for the media center and I will be hot swapping USB drives with sounds, pictures, and videos. Also I will be using network locations for media as well.

Thanks everyone for your help on this.

I suppose you could squeeze a partition to use for /storage onto the end of the 128MB card, since it's empty on a clean install. As it would only be about 20MB in size you would quite soon fill it up when applying custom settings etc.

You could create symbolic links from the /storage partition to another drive for the .xbmc, .cache and .config directories but that somewhat defeats the point of putting the /storage partition on the sd card in the first place. If you just want to do this for fun then go ahead, there's no reason why it won't work.

Using the NAS for storage is really quite simple and works rather well, the following thread explains the process:

http://forum.xbmc.org/showthread.php?tid=149607

A 128MB boot device used to be fine for OpenELEC, but might be cutting it fine these days. You could always try a custom build of OpenELEC that trims away some of the fat (unwanted WiFi drivers etc.).
