The freerunner is going to run 2.6.31, the process to submit code upstream started and will be completed quickly. Due to 3d interaction with dri/drm kernel part, or similar other things I guess the n900 kernel will be stonith at some point, that's a bit sad. > With N900 we don't know yet but hopefully the bootloader will be u-boot. That's nice, the best would be if we'll be able to update/replace u-boot, and have a way to debrick the device if something goes wrong. I found a thread where an n810 user had to pay to "cold reflash" its device in nokia center, I did not dig deeply on that, only was warned. > Also the hardware is very similar to other OMAP3 based devices (OpenPandora, > Beagleboard, Touchbook, even Palm Pre) so the chance of bit rotting is > lower. Previously problematic parts (wi-fi, dsp) are more open now, new May you elaborate please? wifi is exposed normally? may we use wpa_supplicant, hostap for master mode? and about dsp, is not there a "transparent" alsa driver to play anything with any software or to switch connections between the gsm/umts module and mic/earpiece (about that I guess we have to wait a bit more :) ? > 'problematic' stuff is 3d and phone parts. 3d have kernel parts open but > userspace is not, phone is hopefully open enough.

It depends on how much the closed part is exposed and flexible, the linux on phones project needs freedom to grow. I understand the Nokia "differentiation" concept and think this is compatible with "open hardware specs" and "write your alternative OS". Actually OpenMoko stopped development and support of freerunner and there are no plans for developing further devices, the important part is that after three years there is now an experienced community that is bringing to the light the linux on phones project. There is a middleware (www.freesmartphone.org) actively developed and running on several phone devices and really more complete than ofono, and there are a lot of experienced developers that for years are enjoying embedded/mobile world, and finally a lot of brainstorming about all that from common users. It would be very nice if the N900 as of it phone module may be one of the next devices that our community may support and join, that's the reason of my questions. I guess N900 may already fit most Linux geeks needs, and I think I'll buy one of it and join the maemo community anyway, but I'm just speaking about a bigger concept. >> The hardware is exposed by kernel in a standard way, e.g. the phone >> audio connections are managed by alsa while on other fakefree devices >> (like HTC dream) there are some closed source libraries to do that >> preventing the port of opensource phone stack (FSO). > > The oFono phone stack is open. > http://lwn.net/Articles/332820/ There were an irc discussion on that, it was revealed that there is no ofono on N900, but it seems to be in the nokia todo list (I hope with N900 too) so if and when it will be ready this should help in FSO supporting it. Finally, it may be nice if Nokia may donate some devices to FSO and OpenEmbedded core team, any interest/chance about that?
