Hello,

As was announced after the previous Developers Meeting, the next one will take place on February 4th and 5th 2013 in Brussels, right after the FOSDEM conference (http://www.fosdem.org).

I've set up a Wiki page to coordinate the organization of this meeting, see http://elinux.org/Buildroot:DeveloperDaysFOSDEM2013.

I really recommend people living in Europe to attend the FOSDEM conference, it's a great event with lots of interesting talks. And it'll allow you to attend the Buildroot meeting as well!

Interested people are invited to contact me to get registered for the meeting. Registration is free.

Also, if you are part of a company willing to sponsor the event, that would be great, even a few hundred euros would be very nice to help pay for the lunch or dinner expenses for the participants. Thanks for your support!

Best regards,

Thomas

Seconded. FOSDEM is like an ants nest: very busy with very interesting stuff all over the place. You won't be disapointed!

For your pleasure, or your penitence (pick one! ;-), I'll be attending this year!

So: is anyone willing to share a bedroom for the WE?

Regards,
Yann E. MORIN.

I've started adding a few topics to be discused during the meeting, by adding the latest topics that have flown on the mailing list in the past few weeks. I've undoubtfully missed some of them!

Please review, and add to this list.

Looking forward to this moment! :-)

Yann E. MORIN.

Thanks, looks good. I'll try to think about this and add more topics as needed.

Perhaps this longstanding (but minor) issue could be addressed?
http://lists.busybox.net/pipermail/buildroot/2012-December/063482.html

Thanks for the reminder. I've added that to the list of topics to be discussed, in
http://elinux.org/Buildroot:DeveloperDaysFOSDEM2013#Topics_for_the_discussion_day_.28Monday_2013-02-04.29.

Thanks!

Oh, goody. <pkg>_CONFIG_FIXUP is on the list :-) Submitting, final v3 tomorrow, I promise.... just get sidetracked by other things

I think the current state of generating initramfs could be added to that topic list too.

I did some quick testing of buildroot (2012.08) kernel with embedded initramfs size vs. also buildroot kernel but with hand made initramfs inside it (both from the same sources of course)
and the results were 57 MB vs. 37 MB (xz-compressed kernel with no compression for built-in initramfs).

Exactly same software stuff in both but different sizes because different configuration knobs in linux .config-files and different compression methods used.

So optimal initramfs generation (with right linux .config settings and maybe with Gustavo's initramfs patches) with benchmark maybe (size of output, ram taking to load/decompress and speed taking to decompress) would be cool topic. :-)

Stefan

And both tested kernel's included 50 MB worth of firmware stuff, 60 MB worth of modules and
about 10 MB worth of actual userspace stuff (busybox, uClibc and some other stuff)
for total size of about 120 MB uncompressed
