Yep, but i can understand that it's a little expensive device for playing with ... so he sold it.

As a minimum, he should add himself to this list, so it is apparent, that the interest is there, even if he's without a device at the moment:

Thanks for the link. I'll see if I can be added even though its not maemo development.

It seems that you guys are looking for a patch to the omap2 dss driver for Android's double buffer feature. I worked on a gumstix overo platform recently, and got the eclair worked on android-omap-2.6.29 kernel. The patch has been listed on http://elinux.org/Android_on_OMAP wiki page. Hope it helps your N90o porting -

Best regards,
Ming

bdogg64, did you successfully get a working dual boot env. ?

Here is what i get : Android working (except wlan, but i guess i have to replace the "/system/lib/modules/wl*" module with my compiled one on the android fs) but not maemo (reboot loop) :

- Compile the kernel with your kernel patch.
- Copy the compiled modules to the maemo partition (Not sure to understand that, the kernel load some modules from the maemo partition and some from the android one ?)
- Enable R&D

Else the strange thing is with my compiled kernel and modules, without applying the android patchs, all seems fine, but the phone reboot as soon as i try to scan for a wifi access point, and the partitions are strangly mounted ... well, i'll do more testing on that.

Not completely. I was in the same spot you're in as far as the weird mounting but I hadn't worked through that yet. Basically you will have copies of the compiled android modules in two places. In android they will be in /system/lib/modules/. In Maemo they will be in /lib/modules/current/. They will be the same in both places with the exception of the touchscreen driver. I'll have to look through the patches again to find the issue with mounting. I could boot both systems but things like wifi weren't working on the maemo side yet. I was more focused on getting the android side working at the time.

You also have to disable the watchdogs to get out of the reboot loop.

Code:

 
flasher-3.5 --set-rd-flags=no-omap-wd,no-ext-wd -R
