[12:36] <ndec> hi ogra_ ! long time ;-) i was reading about the snappy thing for arm. are there instructions/wiki to create my own snappy images for a custom board? i haven't followed closely the recent 'core' changes, so i might not be familiar with how images are built now.
[12:39] <ogra_> ndec, not yet, i'm workin on that
[12:42] <ndec> ogra_: ok. good. do you know what 'format' or output we will be able to generate for a custom board? could i build a rootfs and use that only?
[12:42] <ogra_> no,  you cant modify the rootfs easily
[12:43] <ogra_> you use the pre-created rootfs with your own kernel,dtb and modules dir
[12:43] <ndec> i don't need to modify it, just want to be able to use it with my board.
[12:43] <ogra_> right
[12:43] <ogra_> http://people.canonical.com/~ogra/snappy/ninjasphere/README
[12:44] <ndec> ah, nice. do these commands work from a container (systemd-nspwan) or chroot?
[12:44] <ogra_> i'm working on a scriopt that allows ypou to easily hand over a kernel, dtb, modules dir and uEnv.txt to it which will then spit out a working device tarball that you can use with the process from the README
[12:44] <ndec> well i don't even have uboot on my boards ;-0
[12:46] <ogra_> oh, then it wont work
[12:46] <ogra_> we dont have support for other bootloaders yet
[12:47] <ogra_> only grub and u-boot
[12:47] <ndec> what do you need from bootloader?
[12:47] <ogra_> izt needs to be able to switch the root target back and forth, as well as the storage dir of the kernel and initrd
[12:47] <ogra_> for the rollback functionality
[12:48] <ogra_> (and upgrades etc etc)
[12:48] <ndec> izt?
[12:48] <ogra_> to achieve that it also needs to be able to touch a file and read from another file
[12:48] <ogra_> *it
[12:48] <ndec> ;)
[12:51] <ndec> ogra_: can i at least 'get' the rootfs without making an image?
[12:53] <ogra_> well
[12:54] <ogra_> the whole magic to atually create an image lives inside ubuntu-device-flash
[12:54] <ogra_> you can indeed pull the rootfs from systzem-image.ubuntu.com but that wont get you anywhere i fear
[12:54] <ogra_> *system-image
[12:55] <ogra_> ubuntu-device-flash essantially does all the snappy specific magic when merging rootfs and device tarball
[12:56] <ogra_> like the dual partition layout, writable and readonly bits, bootloader setup etc
[12:59] <ogra_> does your bootloader support something like uEnv.txt ?
[12:59] <ogra_> (and setting/reading variables ... and touching or writing files)
[13:05] <ndec> ogra_: ok. i will try to use the BBB image and see what i can do with it...
[13:05] <ndec> thanks!
