Which partitioning to keep only linux stuffs

FesterBester38

Hello,

My project is an embedded application that will run on Linux only. To make room in the eMMC I want to remove partitions which are not needed for a single Linux boot. Is it possible - I mean safe - to do this? And how ?

Thanks

If I understand you correctly, you mean how to cut partitions from a multiboot system to a single Linux system?

I recommend not to do it that way. You can start with the single Linux firmware, or build your own firmware.

Thank you for your answer.

I've one more question

Just to be sure. There's an image named "Ubuntu" at this location on the Firefly wiki:
http://en.t-firefly.com/en/firenow/firefly_rk3288/download/

If I use this image while following this tutorial:
http://wiki.t-firefly.com/index. ... en#Flash_update.img

Will I end up with a single Linux with an Ubuntu rfs?

And what about the recovery mode?

Thank you

Yes, you are right.

What kind of recovery mode would you expect?

Well, i don't have a clear idea about the recovery mode. I'm thinking to a mean to boot the processor into a mode that would enable me - for instance - to reload a working kernel version if for some reason the last one isn't working well. There's a possibility to force the Firefly board to boot in a "loader mode" as explained here:

http://wiki.t-firefly.com/index.php/Firefly-RK3288/Boot_mode/en

This loader mode is entered when the RECOVERY switch is pressed at some point during the boot process. When this "loader/recovery" mode is entered, the loader is waiting for commands.

Will this switch still have an effect after the flashing of the single linux firmware?

On other platforms (e.g. Mac OS X) you can boot from a recovery partition and you end up running a lite version of MacOS. Same I think on a Windows machine. Is it possible to get such a "recovery" mode on a Firefly board? In essence, this would be sort of dual boot between a full scale Linux OS+ rfs on one hand and a reduced Linux OS+rfs on the other hand.
