WOW ! That's really one of the very few emails I have seen where someone did all the background work ! :)
I have been working with phones for sometime now and that is actually a lot of useful information !! first you should figure out if someone has already ported android to PXA270, since its an intel architecture, it might involve some work. If no one has ported ( or is working on) this to PXA270, you would have to start looking around for a tool chain that can compile for this processor. The source code is available openly, so once you have the toolchain sorted out, you would start by looking at compiling both the user space android and the kernel. Another important aspect would be to look at the bootloader you have and if it expects some of specific images to be at some specific location(it probably does) and then look at the possibility of replacing it with a bootloader that you can use with android. >From your description, it looks like its the bootloader that handles the flashing of images, this might be good or bad, but we don't know yet. We need to figure out if the bin files that you flash in have to have any specific header/format as well. For this you might want to search online for people putting custom linux images on this phone. Since the signatures are not validated, I am pretty sure someone would be doing that, you just need to find who that person is and get this information. ( simple enough, right? ;) ) Also, I did a quick search and found http://nemustech.blogspot.com/2007/12/android-porting-to-real-target-hw.htmlfor porting android to PXA270 that might help as well with the basic compiling portion. :) Since you do seem to have all the images with you, it should be safe enough to experiment...have fun! :) On Thu, Aug 13, 2009 at 8:32 AM, sigmax <enri...@avalle.net> wrote: > > Hello! > > I've been looking around for some info about android for any phone, > other the T-mobile and HTC developer platform. > > I have a linux based phone, the yuhua Inid, sold in spain as Funker > f901 and in Thailand (where I got it) as i-mobile 904. > > IT has an Intel PXA270 processor at 400mhz, 64mb RAM and 128mb Flash > NAND ram, touchscreen, 2mpx autofocus camera with light.
