Theoretically, you need to copy all content from sd card to flash at the same partitions.
Then, you need to configure boot loader.
BTW, get some loboris distro and see what in install_to_emmc script, to make alike steps with your distro.

I can't tell you more, because I still not have OPI board.

Using SSH i cannot see emmc partition.
  1. OpiElec:~ # df -h
  2. Filesystem                Size      Used Available Use% Mounted on
  3. devtmpfs                400.8M         0    400.8M   0% /dev
  4. /dev/mmcblk0p1          511.7M    113.4M    398.3M  22% /flash
  5. /dev/mmcblk0p2            3.1G      1.3G      1.8G  42% /storage
  6. /dev/loop0              108.1M    108.1M         0 100% /
  7. tmpfs                   402.4M         0    402.4M   0% /dev/shm

  10. tmpfs                   402.4M    236.0K    402.2M   0% /var
  11. tmpfs                   402.4M         0    402.4M   0% /tmp
Copy code


Fourthermore :
Fdisk is not present in Openelec, so the script from loboris cant run

Ideas?

df shows only mounted disks. Check if you see it in /dev folder. Can you post a link to loboris script? Other thing is that his images are using different u-boot, so the script probably won't work anyway.

You are right, but that's true also for other programs. Anyway, this script has no chance working with OpenELEC, because it is too different. However, now that I see what is done, I could try to write something. But first I would need to borrow PLUS board. No promises here.

First of all, thanks a lot for your reply and your work.

May I ask you some other questions?

1) is possible to "open" the read-only filesystem in OpenELEC?
2) the physical power button is not working, is there any possibility to enable it?

Not sure what do you mean with 1). Give an example.

2) is work in progress.

Openelec is a Read-Only File System,  it would be nice if it could be opened (so we can create folder, modify password, etc etc)
In hopes of having a complete open linux-based media center.

But, is just a curiosity.

Thanks a lot for your work.

You can't, This is the point of OpenELEC . it is an embedded operating system built around Kodi..also to prevent people from messing around with the main filesystem and break things and then start complaining it doesn't work (anymore)
It is designed to be as lightweight as possible in terms of size and complexity.

You can put/load necessary files in /storage (and /storage/.config) , which is writable and can be used to load/start modules or additional software packages.
Modification of root password (and adding/changing other things to the readonly filesystem) can only be done by compiling Openelec yourself or by using this method: http://wiki.openelec.tv/index.php/Mksquashfs_Add-on_how-to
