Thanks at all, I have Android on N800 with touchscreen.
I've used the attached patch obtained from NuuNeol patch, modified to work
on TSC2301 driver present on N800 driver instead of TSC2005 present on N810
and applied after patchv1 of android-on-n8xx.
To change between maemo and android coordinate you should insert the
following line in the start_android.sh script:
echo z > /media/mmc1/proc/sysrq-trigger
before the following line:
umask 000
chroot /media/mmc1 /a.sh
Now a question. Since the n800 has not a keyboard, for you is possible and
simple use a bluetooth keyboard to write in Android?
Best regards
Andrea Bernardi
