Hi!
I wonder if there is a repository somewhere which contains the current attempts for loading custom kernels on the Mini Pro. I read that the kexec/miniloader approach might work there, too, but there was an issue with loading the actual kernel (maybe something misbuilt there). I am not particularly scared by messing around with development code which does not work yet, but I think I would be wasting my time if I started from scratch. So where would I start? By using the X10 kexec/miniloader code and building a kernel off the SE sources? Or is there any newer/more fitting codebase?

hey all,
just wondering...
- what is the current status for getting custom kernels running on the x10 mini / mini pro?
- has development of a kexec module or something similar begun based on code written for other phones?
- if so, does anybody know how far people have gotten? what difficulties are we facing at the moment in those regards?
i'm wondering because if nobody has started working on a kexec module then i thought i might try, but if someone is already working on it then i'd be glad to lend a hand if needed / if i can...
cheers,
uriah

a kexec module is a kernel module which reconstructs the kexec functionality (which allows one to execute a kernel from within another kernel) that the linux kernel can have. usually kexec support needs to be built into the kernel (i.e. not a module), but by loading modules such as splboot (which is the kexec module that is being developed in the X8 bootloader bypassing thread based on work that was done for the X10) one can execute a kernel from within the current kernel even if kexec support wasn't built into it.
[EDIT] actually, splboot doesn't exactly reconstruct kexec support, but does something similar. see this post and the few that follow for more details.
Lemme get some things out of the way.. I am a noob. I have searched. I have read some of the results from the search. I am overwhelmed by the 20+ pages of results (lol). I am not 100% sure this is the correct forum for this (not sure where else would be ).. I believe this is one of those things where I need help based on my situation.. Ok, so here I go.
I wish to start porting ICS to my phone. That's my goal. I have general understanding of how linux works, but I do not know much about the android specifics of how they work, or what needs to be modified for this to work. I do not plan to use the kitchen tool as I wish to learn this the hard way. I believe this will help me become more understanding in what I am doing. However, at this point I don't and that's why I'm here. My phone model is irrelevant almost because its prepaid and usually the communities don't even recognize their existence.. at least that's how I feel about it. But I digress. My phone is the zte warp by boost mobile and I am here to learn hopefully the things that will get me started on porting ICS to this phone. I right now believe that the best thing for me to learn is how the android related files work because as it is, I only looked at guides on how linux works and I understand most of it. I'm not sure that's the best thing that will help me port ics, but I'm certain it is important.
Please help me figure out where I should start in learning how to port ICS to my phone basically.
Thanks XDA
anyone? I am quite serious about wanting to do and go into this but I have yet one thread that anyone's ever replied to.. (or post iirc) which puts a damper on me

From my limited knowledge, I think it is a huge task undertaking, you can download Android source code from Google, the hard part will be the device driver development and porting for Linux kernel (and maybe portion of Android). If you are lucky, you can use the existing phone bootloader (or you have to port one). Understanding the inner of the phone (different chip set may need different device driver) will be another challenging task.
by the device driver development, you mean all the libs that go into the phone? Couldn't I just copy/paste the pre-existing libs that are already made for the phone? Also the phone im working with is a bit strange really.. noone has been able to compile the kernel from its source and get it to boot yet.. when it was compiled the zImage was different than that of the stock one.
And yeah, I have downloaded the aosp source.. I just need to know where to start at and the processes involved really

To answer you question no the drivers and lib files are different for aosp based rooms then they are for the stock OEM from. The first step will be to get a working kernel. Without anything you do will be pointless
I'm somewhat interested in the same thing, and from what I've gathered, you'll need to do these things to begin ROM development:
1. Read every page on the AOSP site and grab a copy of the AOSP source. It probably wouldn't hurt to read the regular Android developer wiki as well.
2. Learn about Linux driver development:
http://lwn.net/Kernel/LDD3/ (this is apparently considered THE BOOK on Linux driver development)
http://www.freesoftwaremagazine.com/articles/drivers_linux
3. Learn pretty much every detail about your phone and its hardware, especially when it comes to how ROMs are installed on it. For example, my phone (the Droid X2) has a locked bootloader, so 2nd init has to be used to boot new ROMs, and this makes it so that we cannot update the kernel.
You can usually find this sort of information on your phone manufacturer's website. Sometimes they even post the source code to their phone's drivers, which is helpful.
4. Look at other ROMs (preferably for your phone) and see how they work. The source code is freely available for most popular ROMs.
For example: CyanogenMod keeps their source code in a public git repository: https://github.com/cyanogenmod
5. Get to work on porting!
I would highly recommend starting with something smaller, however, just as a start. One good jumping-off point is probably this guide: http://forum.xda-developers.com/showthread.php?t=1272270
If any part of this was wrong, or if I left something out, somebody feel free to correct me, I'm still a noob.
Thank you so much for your direction, however,, android kitchen.. im not sure about that because isnt that only ment for htc devices? My phone is made by zte
what device do you even have?
if it's stuck officialy on 2.1 or 2.2 there's no hope that if you even port it that it'll work
its the zte warp from boost mobile (prepaid). Btw if I compile an aosp ics launcher and put that on my phone whats the chances of that working?
edit: it uses 2.3.5
Well Sebastian responded on android forums, apparently zte is very bad at version control with their kernel sources. So when they complete one project, they use the same source for the next project, and what they release could be for anything. Apparently the blade source had the same issues, it took him a while to get them to correct the source
Sent from my N860 using Tapatalk
Yeah I noticed that there were ppl saying there were things similar but I'm not sure what will work or what won't.. guess its time to start a petition on zte to release the source code lol
edit: seems like zte's bein a bad company and violated the GNU GPL license for not providing a complete source code.. I compiled an email and sent it to someone who can proof read it and send it to the right person for this kinda thing.. danggit zte
I am looking for a XPERIA Mini Pro (mango) kernel that has USB_SERIAL built in or as a module.
I realize I could go the extra mile and compile my own, but I thought I should ask first!
(I need it to talk to my arduino)
Hello.
I am very keen in getting the Ubuntu Touch ported to my Xperia Z2 phone. Obviously, I'll need all the help and guidance possible.
What I currently have? developer.ubuntu.com/en/start/ubuntu-for-devices/porting-new-device/
I'm using the official porting guide as checklist. Below are what I have accomplished so far with the guide
Setup my Development Environment
Have built for Nexus with success to see if my environment is up and running (the building threw no errors, so I assume it "works", since I have no means of testing because I don't have a nexus handset)
I have added repos regarding under how to enable a new device.
I have done the first part of the Device specific changes using the check-config script, the _defconfig file in the kernel (this is Sony Xperia Z2 kernel: CyanogenMod/android_kernel_sony_msm8974 , right?)
When I did the build ( just to test so far what I've done ) I got the error that, its using the pre-compiled kernel, or something like that.
Now my questions:
How do I tell it which kernel to use, and where?
Where is the pre-compiled kernel and which is the precompiled: the one from the vendor/ (which I got from extracted binary from sony official) OR the /kernel/sony/msm8974 ?
I've gone looking around to see if I could perhaps follow the pattern used in the porting to the Xperia Z, since they're in the same series. Yet, I hardly could follow what exactly the 'porter' did. I was interested in finding answers to the 'What?', and 'Where?' of the porting done, but couldn't get solid answers.
I ask this here with the hope that, a developer who's been through the porting process will be able to offer assistance. I've been in touch with Mamenyaka, and along the lines, he'll be assisting too. But since he isn't available all the time, I ask this here.
Concerning the above list of questions, please, any assistance will be appreciated.
Its understandable, yet unfortunate, that the official ubuntu porting guide has been made to be so broad and so generic its hard to streamline what it says with a specific device. With this thread, I hope to get very specific instructions precisely tailored to the Xperia Z2 and to accommodate being extensive, instructions for the Z line series.
thanks

Hello,
if you are still working on this project:
Your Problem was not that you used the prebuilt kernel, your problem was that the script doesnt use mkabootimg correctly. For sony device you have to use another command.
Friend i would love to see ubuntu on my z2
share a link which may be helpful

Hi all!
I've been looking for resources or tutorials on how to port a custom kernel like franco kernel to a currently not supported device, but seem to not be able to find any.
I'm a programmer myself, although I'm not very familiar with C, I think I'm still comfortable to make some non-drastic changes to the code. I've never worked on kernels or OS before, but it's going to be fun to learn new things. Since my goal is just to port an existing kernel, I think it's not going to be too hard in comparison to adding new features to the kernel.
I currently have a phone with already released OEM kernel source code, and would like to start with porting a custom kernel to it.
Thanks in advance to anyone who can point me to the right direction!
