The SD card uses two partitions: "BOOT" (which is FAT formatted) and rootfs (which uses the ext4 file system). You can replace the rootfs partition with any other distribution's root file system, if this distribution is able to run with the Parallella kernel. However, this requires some knowledge on how a Linux distribution works, and it won't give you all the niceties of a real Ubuntu installation on a PC. This is due to the fact that the Parallella kernel is a customized kernel and the Parallella boots in a different way than your average PC.

Oh, and without installing the eSDK manually, you'd lose access to the Epiphany chip on the Parallella.

And tryed to boot parallella following https://ograblog.wordpress.com/2015/01/ ... mhf-board/ and text file http://people.canonical.com/~ogra/snapp ... system.txt
And couldn't load. I edited above text file for boot. but it didn't help.

As I wrote, you need to replace the rootfs partition, not the BOOT partition.

For the U-Boot logic... you might want to connect a serial port and do the research yourself. The Snappy boot system looks a bit complex, so you'd need to port that over.

found that main boot file is snappy-system.txt located in boot partition ( https://ograblog.wordpress.com/2015/01/ ... mhf-board/ )
tried to boot similar to manual for raspberry http://people.canonical.com/~lool/rpi2/README.txt
and could't boot,
it seems we need something different for parallella
