I can compile a Linux kernel for this ereader and install a linux distro?
and drivers (touch, wifi ...)?
or I can modify and compile a kernel android and use it as linux and compiling the necessary programs?
the request may seem inconclusive but the distro that I use has just released the toolchain for the arm architecture ( http://forum.tinycorelinux.net/index...c,13835.0.html ) and I would try to make it work on nook simple touch.
Thanks!

There have been other efforts along this line, but none successful that I'm aware of. I believe the touch screen drivers are a major stumbling block.

Thanks for the answer, strangely I do not get the feedback messages and I did not realize you had answered me.
the nook should not be open source? and in the worst case we could not reuse the driver taking full with no changes?

Sorry for a lame question, but i've got a problem. I've compiled a simple hello-world application using arm-gcc 3.4.3 (compiled under x86 linux using gcc compiler for ARM) with default settings. When I was trying to start it under Universal, I got the message 'Invalid instruction' (or something like that).
Please provide me with a working example (command-line arguments for building and etc) or some instructions on build process, if anybody has one.
Thanks.

You don't tell where does the gcc-3.4.3 come from.
With the 3.4.1 stadalone toolchain from
ftp://ftp.handhelds.org/projects/toolchain
it is just
Code:
/usr/local/arm/3.4.1/bin/arm-linux-gcc -o hello hello.c
If you want to compile GUI apps or big packages, then you should read
http://www.openembedded.org/wiki/GettingStarted
I downloaded it from www.gnuarm.com. It worked OK when compiled ROM images for my ARM7TDMI-based boards.
Thanks for the link, I'll try it today.
And, finally, another lame question: did anybody tried to build gcc 4.1 for cross-compiling from x86 to ARM? Or it is possible to use the script from the FTP to build it?

After reading this i thought it is possible to bring this to our omap 850 devices so i just want see ur views
you can use e17 booting angstrom + illume thanks to wing linux project
but there aren't angstrom image ready to load you must compile...
As gp.triple pointed out, it should be possible to do. As Wing Linux uses Angstrom+Android so Angstrom+E17 shouldn't be a problem.
And pitillo on #wing-linux mentioned a couple of days ago that he was trying to build it for elf (aka Touch, another Omap850 device). If he succeded in making one, it should run as is on our devices.
Personally, I prefer having a Kernel that supports all Opal features before worrying about builds and packages. And sadely, I'm not having lots of success there
Anyway, check the link in my sig if you want to know more about Wing Linux.

're right I also think that before we have a working kernel and then you can choose what you prefer
Linux is freedom
i tried android wing linux already , its cool thnx musik monk
I am trying to find information on how to poke around my own phone's source code (if possible, Sprint HTC Hero) and also the Android Source Code which is downloadable.
I'd like to see how the apps look, and how I could change them. I also want to know how to go about editing and loading that source code up on a phone.
Is this possible with my phone? Or do I need a special phone to do so? I'd like to know how these folks are going about creating these special ROMs for phones, and how someone can edit it to their liking, and then compile it for a specific device.
source.android.com is where you should find what you need.
I did find that, and it works someone, but the address isn't right, and for some reason I can't install an older version of Java on my Ubuntu VM. Maybe because it's 10.4? Has anyone else been able to download the source code via Google's instructions? On a newer machine?

If you add the Jaunty repositories to your sources.list file you should be able to download sun-java5-*
If i find the exact apt lines I will post them later.
Another thought - Switch to Debian Lenny - I switched from Ubuntu after I upgraded to 10.04 and absolutely hated 10, but I am loving Lenny.
EDIT:
add
deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
to your /etc/apt/sources.list
then do
apt-get update
apt-get install sun-java5-jre sun-java5-jdk
Thanks for the update, I'll try that and see how far I get.
From what I gathered, Ubuntu was the only supported Linux operating system that I'd be able to get the source code of Android for...
I understand that the size of Android is so massive, an organized way to download it is necessary, but why isn't this just simple like FTP access?
http://htc-linux.org/wiki/index.php?title=Mega
i read that the kernel is same wont that help porting andriod with respect to some drivers change!!!
no one answered
the problem is our first developer can't keep the android project...
hi
how can i debug this files and run???
currently I'm trying to cross-compile a most recent wildfire kernel I found on htc server using a configuration I personally made for our mega. The problem is there are many errors in the source code...
re.:
In my opinion we start build android from beginning. My problem is in my OS on my PC. I have Windows XP and building and modifing found only on Linux. I find this page with porting guide. It is step by step How to create boot screen, How to setup Connectivity...
source.android.com/porting/bring_up.html
On this page are programs for debug and download android source code...
Anyone write.
Move to general as not rom development
I'm using linux, this is why I want to try to cross-compile a kernel for our device, like I just said, source code has a large number of errors, I don't know why...
if you are interested, I can share the kernel configuration I made myself...
Now I install Ubuntu 10. It was compilation found in this version of Linux??? Where programs can I download? Now I have Git, Eclipse and Python 2.7. How can I install .tar packs on Ubuntu zito882000?
if you are new as a linux user it's quite difficult to explain, you need gcc plus the same programs a normal user has to compile a kernel.
The difference is in the way of compilation, a parameter that does a compilation for arm architectures....do you have some kernel compilation experience?

windows is gold.
with compilation i haven't any experience. I only begin in programming languages C, C++ and VB. I compile only my apps in visual studio. And i have nice experience with photoshop.
it isn't exactly the same thing, in a kernel you have a large number of drivers to compile, not a only one program...
Here cyberciti.biz/tips/compiling-linux-kernel-26.html you can find a simple guide!
The most important part is the command "make" that need some different parameters to do a cross-compilation for ARM processors ^^
thx
I saw the instructions and understand him. If I somehow help you write to my icq: 484038954 or Skype: vasek-smekal.
So far, thanks
I just bought an HTC Hero with native android.
If you want to try again I share with you my kernel configuration file and a link where you can download the kernel source I used.
(remember to rename "config.txt" in ".config" with the point and without the extension)
KERNEL SOURCE -> http://developer.htc.com/ (must choose "HTC Wildfire - Froyo - 2.6.32 kernel source code")
ARM LINUX GCC -> http://www.handhelds.org/download/projects/toolchain/archive/arm-linux-gcc-3.3.1-030820.tar.bz2
, lets be honest: are ****.
Unstable, Buggy and **** like that.
And instead of just complaining about the devs* I want to know the following:
If I want to contribute on the code what do I need to learn? Since a while I'm teaching myself Java and Python via Solo Learn. What would I need to learn to contribute to the Android OS Code itself NOT APPS!!
It will take me months, years I am aware of that. But I'm just tired of only trying different Custom ROMS, only to see that most of them aren't a real alternative of the Stock Roms, without having the possibility to do something about it.
So feed me with some input. What are good sites to learn that?
Happy for your feedback!
*Because damn I know that the Devs are doing an amazing job!
Google is a good start.. that search engine can point you in the right direction ?

It really depends on what you want to do with Android. The upper layers are in Java. The lower layers are in C++ or C. If you want to adjust the stock libs you might have to understand ARM assembler code. Also a basic knowledge of microcontrollers and linux kernel does help (especially if it comes to the graphic and camera subsystems).
There is almost no documentation for Android (the code is the documentation) and the subsystems change from version to version. The best way (and probably only one) to learn Android is hands on. Just try to fix the most annoying bug you encounter. Try to understand how the source-code works. Check how the Java, C++ layers, kernel and the stock libs interact with each other.
Also try to understand the adb logcat output.
Also try to understand the G800F device tree. A first step is also to compile the source yourself.

Dear hennymcc,
it is about your TWRP for G800F.
Everthing is ok, till it comes to a restore of a TWRP backup.
After the restore the S5 Mini is in a bootloop.
I have tried it with the version August 2015 and March 2016.
Is there any solution?
Thank you.
