[android-porting] Re: Very basic questions about porting and my linux based phone.

[Jerome Duval]

You're in luck (sort of)! The PXA270 is an ARM processor and it's the same as the axim x51v (and possibly other Axims, I'm not sure). The sort of comes from the fact that I have no idea what the patches to apply to the cupcake tree are to get the Android image for the x51v, as they haven't been released yet (I'm going to check out the port to hw link previously mentioned in the thread and start from scratch soon. Just need to get annoyed enough at the waiting on the axdroid project). You should be able to recycle some of the code to get yourself started on your device. Jerome sigmax wrote: Hi Abhinayak! Thanks for your quick answer. Yep, I did lots of search. There is nothing more about this phone. It has been sold in Europe, mainly in spain, at 139 euros by a company called "funker": http://www.funkertech.com/funker901.htm It had also been introduced in Thailand by i-mobile, portraying it as one of their best phones: http://www.i-mobilephone.com/form/tha/F_MobilePhoneDetail.aspx?brand_id=10&series_id=5&id=954&lang=en Both "brands" got it from yuhuatel design house, a chinese based phone design company. http://www.yuhuatel.com/english/i-nid.php And I bought it at (yup, believe it) U$S 11,51 from ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380140198668&ssPageName=STRK:MEWNX:IT I live in Uruguay, South America. This will be -if I dont render it useless- my phone, as my old phone is quite battered. I found actually two utils: One that wrote the NAND based on several separate files (which are plain, non signed, easily mountable / readable ext2 and ext3 images) which also has the ability to pack all those files into a .bin image, and a second utility that uses that bin image with all the files inside, to write the nand. One was from funker company, the second one I found in an anonymouse sharing file service, thru googling. I alredy peeked around inside the ext2 images, and i can see the /ext/ initr.d etc. I can confirm that the phone works with a qtopia based linux. It is very similar to the qtroll GREENPHONE. I am NOT a proficient linux user, much less a linux coder. I do work as programmer but with .net languages. Anyway, I think I understand what you say. I can only hope that someone with the necesary knowledge and one of this phones to bite the android apple :) Or if anyone feels with enough resources (mainly time and interest), I am here to perform whatever test / errand required on my phone.

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 foundhttp://nemustech.blogspot.com/2007/12/android-porting-to-real-target-... 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. It seems to cope ok with minimum requirements for android phone. The process to get its nand flash rewritten is suspiciously similar to that of HTC android enabled phones: First of all, I have to install an USB driver with the following label: "Intel PXA27X USB Serial Driver Installation Disk" On the phone, then I got to press and hold a buttonl, plug it in the usb port, and it is recognized as a serial port. I have an utility, downloaded from the phone-brand website, installed on the PC  that allows me to load different libraries and files, and from there  they get uploaded into the NAND on the phone... Actually, the utility reads either a large .bin file (which as I coud see, is comprised of the different libraries and files, all packed inside) or each file separately.  The files are open, no key / encription or whatever is used. Mi linux and phone development knowledge is close to null. So please excuse me if I am just writing obvious things. The individual files that this "phone upgrading thingy" loads and burns into the phone need to be loaded under the following titles: Kernel, root FS, Program FS, User Data FS,  User Local, Tat, Grps2121, patch, SysParm_Ind, SysParm_Dep. OR else I just select a huge BIN file wich seems to have inside 7 files packed in it, that get stuffed (it takes 30 minutes) into the phone. Can anyone tell me if they recognize any useful information from this ? Is there a way I can install android on this phone ? What kind of info is needed (I can search!) ... anyone is willing to help me ? :) I would really love to see this phone get revamped with ANDROID, and actually I know that the yuhua design house, is actually about to sell a "from the beginning, android phone" which is suspiciously the same as this one. I can only add that I am willing to test anything you throw at me on the phone.
