Just want to make sure everyone looking at this thread knows about stlc45xx: http://stlc45xx.garage.maemo.org/ http://www.gossamer-threads.com/lists/maemo/developers/40485

Hoping some kind kernel hacker will be able to extend this to work with 770′s stlc4370 wireless chipset. That would be like a magical gift from unicorn land!

Thanks.

@marcin: oh, I see. In that case backporting omapfb changes could make Poky working with 2.6.16 (at least for 3.1 which is perhaps already old :-) But I wanted to do it anyway for other reasons.

@fanoush: Richard Purdie reminded me why we moved to 2.6.18 kernel -- we had to get rid of older X-Server which was in OS2006 as it was from non-modular times.

@fanoush: We use xserver-xomap 1.1.99.3 (iirc OS2007 one) on all tablets. Kernel patches are in meta/packages/linux/linux-nokia800-2.6.18-osso40/ directory.

“I guess the question about Poky kernel can be answered by experiment :-) Will try to flash just the jffs2 to 770 next week and see.”

Tried with default 2.6.16 and it fails somehow when x-server starts. It somehow makes sense, omapfb is updated in 2.6.18 and screen update ioctl changed, if x-server uses new ioctl with x,y window coordinates it won’t work. Will try to backport this to 2.6.16 to see if it makes difference :-)

BTW where are sources/patches/config for http://pokylinux.org/releases/pinky-3.1/zImage-2.6.18-osso40-pinky-3.1-nokia770.bin ? tried to browse poky svn http://svn.o-hand.com/repos/poky/trunk/ but got lost quickly. At least the first Nokia 2.6.18 source for N800 was incomplete for 770 build (omap1, dsp and 770 board sources missing/old)

To find mameo-related stuff, please feel free to use tabletSearch: http://www.google.com/coop/cse?cx=014783630360138230012%3A5hwd9yj0uno

You can also download it as a plugin-engine for the Maemo Internet Search appelt on the Hildon desktop.

Yes, but does Poky depend on any specific kernel feature? 2.6.18 is ancient version anyway so why not to use stock 2.6.16.27? Because otherwise you can omit kernel from Poky distributon altogether (so you don’t need to make the choice) and leave just rootfs. This allows people to keep their current kernels and dual/triple boot Poky/Debian/whatever with Maemo (via bootmenu). Framebuffer console or framebuffer automatic update itself is solvable without new kernel, see http://www.internettablettalk.com/forums/showthread.php?p=167845#post167845 for recent verification.

Sadly we currently don’t have kexec so we are limited to one kernel. Once we have kexec it is not so critical but still multiple kernels add complexity both for people to manage them properly on the device and kexec would slow down boot procedure and make it more complex too.

I guess the question about Poky kernel can be answered by experiment :-) Will try to flash just the jffs2 to 770 next week and see.

Sadly making WPA possible on 2.6.16.27 is not any easier, you just don’t need to fight with umac.ko. BTW in your experiments with cx3110x I don’t see wlan-cal call, you need to call it before wlan driver is ready (chroot /mnt/initfs wlan-cal)

As for documentation – maemo.org, http://www.internettablettalk.com forum and mailing list http://www.gossamer-threads.com/lists/maemo/ is searchable.
