From: binary-nomad on 27 Apr 2006 13:24 Hello! Can someone tell me if there is any way to replace the "OS" that manufacturers provide on various types of handheld devices, eg. the Gizmondo, PSP, different PDAs....., and replace it with something else? Also, where is information on these devices (technical docs) and how to program them? (I'm just a hobbyist, not a big software company of any kind). I'd like information, for example, on what CPU it has, how much memory, is there a ROM of some kind and what does it have on it, and also how to program any other hardware that may be there, eg. a USB port, or camera etc. Thanks.

There is an active project getting Linux to run on Ipaqs (google for linux ipaq for information). It used to be possible to get an SDK for the Palm Pilot; presumably that's still the case. -- Joseph J.

I looked into this a couple of years back; it was at that point a somewhat immature project, and not exactly ready for prime time. But it showed promise, and seemed to have some official support. However at that point it seemed nothing had happened for a fair while... OTOH, the iPAQs (amongst others) run WinCE Pocket PC, for which a VC++ dev environment is a free download from Microsoft, along with emulators and various other bits. Works well. One downside is that certain things like Bluetooth use 3rd-party stacks, for which the APIs are not free - we made do (for a prototype) with a nagware version, which worked fine (if you ignored the nag screen...).
