C and .img start point - Acer Iconia A500

Hello,
I have an Acer Iconia a500 with Skrilax_CZ's bootloader V8, and I was wondering how to make my own firmware from scratch, in C.
How can I make a .img to install it on my tablet?
Is there a good lib to use in C for this tablet?
There is a lot more questions I would like to ask, but this two will be a good start.
I know it's a big project to make my own firmware, but I rellay like low-level programming!

well it's a linux kernel modified to run this tablet on android GUI
tegraowners.com has developed many kernels for this as well as a lubuntu front end with the latest linux kernel.
the android development is closed code but the linux kernel development is posted to github and maintained
perhaps that is where you want to look.
I doubt that you will get much step by step from the developers but the linux kernels should get you a good starting point

if it would be that easy, everybody would do it
what do you mean by "good with computers"? do you know how to write code (C/C++)? are you yet experienced with running linux? have you ever compiled a kernel before? do you want to make a source-(AOSP)-rom (then you can get the source here: http://source.android.com/ and here: http://opensource.samsung.com/) or do you want to just theme and customize a stock firmware?
i think there are already some tutorials around which will help you in the beginning. just google for them!
i haven't done custom rom development myself but i would really like to get some (clean) aosp goodness on this phone. i am experienced with linux (use it since 6 years as primary os) and i can code c/c++/asm. so if you are in fact serious and able to go all the way. i would appreciate to help!

I'm pretty able to develop with Eclipse, so android sdk. Linux quite good, i prefer to use windows, but i know linux is necessary. First of all i'd like to know how to customize GALAXY fw and then i'll study how to compile a kernel, no one during my life helps me, and it's difficult for me because i'm not good with english and all tutorials are in english!
I'll try to work on it! Thank you
Can someone explain me how to cook a Galaxy S Froyo ROM with AOSP as the base and samsung drivers?
Could someone please explain to me how to flash the Korean firmware onto the European phone? Really need the native "record call" feature
I saw some instructions posted here
http://forum.androidcentral.com/hacking/40130-100-stock-captivate-rom-aosp-source.html
It's not difficult if you're comfortable with linux, shell scripts, custom kernels, and cross compiling.
Basically that's pretty much all it needs, Android systems are very similiar to a running linux system.
Boot off a bootloader (usually closed sourced) into kernel and initrd, then init loads the drivers, system and configs, after which is pretty much to your taste and likings.
Source code of android, samsung kernel source, are available online, google is your friend.

compiling your own roms

so... here's what i'm thinking.
how about setting up a vmware machine with all the source code for android on it, so that when a new version comes out, you can compile your own rather than waiting and then flash it to your phone. you could add your own modifications and any others that are out there.
this is a win / win situation as you get your own compilation, your own custom build and can screw about with the code it as much as you want as it's on a virtual machine.
you could update the android source code by pulling it online. and because it's a virtual machine, you don't need to worry about compilation issues across different machines.
i'm thinking about doing it - who'd be interested?
That's what I'm doing. It's FUN but to be honest it's quite a pain in the a$$ when you sync the master branch, compile, flash, and found out that the resulted ROM does not working properly and can't find any information about how to fix it.
BTW, I can hardly find the info on modifications -- most topics here are ready-to-flash ROM releases but no info on development. I did found some useful information in Nexus One forums, though.
Any suggestions on where can we find the resources regarding compilation and modification of AOSP?
well, my instincts tell me the modifications are "closed-source", hidden away from you. who knows what sorts of nasties are in the actual rom that's sitting on your phone. logging your every move, grabbing every site you visit, logging everything you type etc.
so, what's needed for a more successful dev community as far as i'm concerned is to allow the users to pick and choose what mods they want. this is an adp after all, and is one of the easiest phones to compile for.
so, if there's an active community compiling their own roms, then mods will perhaps become more open source with diffs / additions to the android source, which in itself will be better for users, developers and heck, who knows who might actually add it to the android source?

[Q] Creating a custom ROM

Hello. I am interested in building my own ROM. I have some computer knowledge, but I want to know, what tools and files do I need for creating one. So maybe someone can guide me or point me to a tutorials. I basically just want to try some things.
Is there a way to brick my phone by using a custom ROM?
Also, what is android 2.3.5? Google's latest is Android 2.3.3 .
Android Latest stable release
Tablets: 3.2 (Honeycomb)
Phones: 2.3.5 (Gingerbread) / 25 July 2011; 38 days ago
Latest Android release is 2.3.5 for phones
good new, should be more like you.
Latest android for smartphones is 2.3.5.
Regarding advices to build a new rom, nothing better than to speak to those that already did and have the knowledge (stcokwell, DZO, FFranco, Knzo, etc)
Search the posts of each rom and speak with respective developers.
Good luck and I waiting for your rom to test it
I'm interested too, but it requires more knowledge about linux. Kernels and so on.
So i'm thinkin is better to build kernels, there is sources, there is websites with how to and so o.. rom is more complex.
I'm bringing this thread up now.
I am currently downloading CyanogenMod's source, because of what I've read android.git.kernel.org is down. My first idea was to do a proper scene port of the latest Android. But well, this has better documentation anyway. So, I haven't got the source yet to browse, but is there a way to make a general build and if I understand correctly, it creates me a system.img? How to make it flashable by recovery? And if it fails to start, can I still get to the recovery? And about kernel, this has to be modified too, right?
And for last, if anyone has a good Android source code browsing/modifying e-book/video/whatever, can I have it?
-e-
I found that CyanogenMod can automatically make a signed .zip and on normal Android AOSP I can make it with "make otapackage". Is that right?
Any good read?

[UBUNTU][Kernel 3.1 IMG] Could someone post some .zip's?

Well, I tried to get that Ubuntu up and running, and I did. Partially.
Finding a WORKING 3.1.10 Kernel isnt just freaking possible.
I spend like 2 todays on going through google
-> arm debian kernel, arm7hf debian kernel and I didnt found anything in terms
of a compiled .img file for download but plenty of methods how to compile it myself.
Well. I dont get it since there are pletny of people obviously doing Kernel Dev here.
I would love to compile arm7hf kernel but the wiki stuff is outdated.
Can someone please put some .zip files online? (if you need online space PM me)
I'll be really glad about some decent version of rootfs and a kernel 3.1
Gentoo? Debian? Ubuntu?
Thank you in advance,
Man ... Q&A-Thread please!

[Q] which AOSP 5.0 ROM for building yourself?

I am NOT a developer!
I am a Systems Administrator, and I have built a 4.2 before using ubuntu 14.04, with a SGS2 i9100.
I have attempted in the past to ask for a device tree so I could build my own pure AOSP, and no one was able to help me.
SO, I now have my hands on a S4, and I want to put 5.0 on it.
I can create the build environment. either the windows version or the ubuntu version.
What I would like to know is which ROM would provide me a bit of instructions on how to use and build their ROM.
I'm looking for a ROM as close to AOSP as possible.
Preferably without any CyanogenMod builds, but I hightly doubt that is possible.
Seems everyone is using them for some reason.
I've been going to the ROM's section and I see no instructions on how to BUILD the rom.
Sure, I see their Github, but no info in what environment its been build in.
Can someone assist in helping find a ROM, so I can contribute to this community once I get the feel for it?
thank you!
You can try building cm to understand the basis, then move to aosp
