It is fairly easy to make an adapter that slots into the simcard hole. Only one thing you need to be careful; make the adapter so that it has a slot on the middle, or make it so thin that it does not bend the actual sim-connectors in the device. Doing that will give you problems later if the sim contacts do not connect well to the card.

If the voltage is cut it depends on the memory device on how long the old state is held in the device.
What I'm concerned about though, is that ubiboot logging to the RAM buffer would overwrite whatever's remaining in RAM.
The copy code would have to be placed really early in boot, maybe to a procfs entry, subsequently copied when ubiboot-menus is launched.

Something I thought of today triggered when I thought about the status led flickering in R&D mode... I think it just shows up CPU activity, right?
Well. why not make the status led function as serial output!
That'd be lot easier than using the AUX output, since you'd not need any fancy modulation schemes and the bandwidth would be eornomous
You'd just need a photodiode hookup that you'd place on top of the led, converting it directly to serial signal wired to PC

Shouldnt be to hard to implement. Well, kinda'

@hurrian One thing. The iptables redirect () seems to have gone haywire in cyberspace again
http://talk.maemo.org/showpost.php?p...5&postcount=42
At least, again this message shows up e.g. in ettercap:
iptables: No chain/target/match by that name.
Which is connected to CONFIG_IP_NF_TARGET_REDIRECT

kernel-plus 2.6.32.61 r6 focuses on btrfs. It has been enabled as [Y] in the kernel.
Note that the disk format as used in the kernel probably matches 2.6.34 - ubiboot definitely has not been updated to support reading from this version of the btrfs disk format. Play with /home or something.
Meanwhile, or if you're feeling adventurous, load zImage from somewhere other than the Harmattan rootfs (check ubiboot.conf)
