Compiling CM11 for SM-T230NU

[troy5890]

Hey guys its troy here and this thread is to focus on getting a custom rom or Cm11 rom on this device (SM-T230NU). What I have so far is two devices that run a Marvell processor which is a samsung galaxy tab 3 7.0 and Nvidia Shield tablet. Now I'm trying to look for the one that's closer to this devices specs. After that I will try looking for their source and see if I can compile a custom rom. It would be really helpful if a dev can help me out with this along with you guys. So who's ready to have CM11.

Is the kernel source you linked to build a custom recovery

Sent from my SM-T230NU using XDA Free mobile app

the kernel source is required to build boot.img and recovery.img
you have a huge amount of reading to do. the galaxy tab 3 device forums have a large amount of information
in general and q&a to get you up and running.
http://forum.xda-developers.com/galaxy-tab-3

specifically this thread
http://forum.xda-developers.com/showthread.php?t=2792872 to gain an understanding of the process

and this thread
http://forum.xda-developers.com/showthread.php?t=2812791

especially page 2 look for @Restl3ss posts, he's the one who got me set right.
when you have a question start by searching and reading, then ask your question, and while you wait for an answer
which you may or may not get, continue searching and reading.

i started a full cherry noob in like april or may and have learned alot, just to give you an idea of what your own
process of growth and learning may look like. :good:

the kernel config is almost the same. you can use it for stock and custom roms and of course for custom recoveries.

Alright I decided to start developing on December 19th. But I have a question. Is there a 32-bit version to do android development instead of 64-bit?

android as you and i know it is 32 bit so you will be building a 32 system.
But to build android you require a 64-bit system [linux/mac] you just do.
However you do not need a 64 bit system to compile kernels.

search the difference between 32bit and 64bit systems and almost all questions you have on that subject will be answered.
Except maybe this one....
while you can only run 32bit applications/code/toolchains etc. on a 32 bit system
you can run both 32bit and 64bit stuff on a 64bit system.

if you are compiling code on a 32bit system you need a 32bit compiler/toolchain
if you are compiling an android kernel [32bit] on a 64 bit system you can use a 32bit or 64bit toolchain
as you will be cross-compiling, meaning compiling code on one type of machine/system [host] x86 or x86_64 [architecture]
to run on another type of machine/system [target] - 32bit - arm [architecture]
i would suggest using the 32bit toolchain.

Well I'm trying to compile a custom rom. Would I be able to do so on a 32-bit window system running virtualbox with ubuntu on it?

Hey guys I don't think I can do this because I have a 32bit window system and I can't build cm11 for this device. I need a 64-bit system to compile so I'm sorry if I got you guys excited about this.
