Only the code never made to official 770 kernel but is/was part of released N800 kernel. Sadly last time I tried and ported this code back to 770 kernel it just hanged the device and the interrupt on TE pin never arrived. I'm suspecting the sossi TE pin needs to be enabled somehow via some platform specific (omap1) initialization code that was not part of N800 kernel. The failed attempt is here http://fanoush.wz.cz/maemo/2.6.16.yuv420+tearsync-not-working.diff
Got no reply here http://lists.maemo.org/pipermail/maemo-developers/2007-May/010156.html but something here http://www.gossamer-threads.com/lists/maemo/developers/22701#22701 Also on the similar 'banging my head against the wall' kernel topic - some weeks ago I downgraded my N800 back to OS2007 (as I have N810 with it, the N800 touchscreen is much worse in OS2008 and I like speed of Opera and the system i general). Also since I boot from mmc I flashed only initfs and kernel (i.e. not bootloader). Then I noticed my external mmc slot does not work. Flashed to OS2008 back - it worked again, flashed back to OS2007 - no luck even with original Nokia kernel. I spent some time digging in kernel source and even backporting changes in mmc stack from 2.6.21 to 2.6.18 with no luck. Finally I had an idea to flash bootloader too (over USB, kernel and initfs can be done on the fly from the device so one could sort of dual boot between OS2007 and 8). After doing this my external mmc slot magically works again in OS2007 (NOLO is downgraded from 1.1.7 to 1.1.6). This was a bit discouraging and tells me something about chances of getting tearsync code working without proper HW initialization and bootloader sources :-) Frantisek _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
