Someone care to explain the benefits, if any, of this? My understanding from what little i read is it will help with kernal development on a decent number of samsung devices.
Edit: as in should i be "super excited", "meh", or "cool beans".
second that question .. does this help us?
Would this driver be the one that controls download mode?

Maybe this?
added: Should have checked supercurio's github
Samsung v1 GT-I9100 sources: [common] param.lfs/j4fs driver (communication with bootloader), now OpenSource, yay!
google :
j4fs...
its a filesystem.... FACT
So my GUESS...
a driver for a filesystem...
like ext4 and fat drivers for handling our other storage..
a new filesystem for us to tweak the crap out of and use..?
though ive been wrong before. that is only a logical conclusion not a factual statement

according to the post above you this may be the file system used for the bootloaders on the sgs2 so it would help those folks when hacking.
J4FS porting released
If someone is still interested I've just finished the porting of the J4FS on 3.1.x kernel adding support for normal "block device" (for loopback image mounting).
movitool.ntd.homelinux.org/trac/movitool/wiki/j4fs
Hope this can help...
Ceers
Nitro
And another tool (standalone) to extract j4fs/lfs images (eg. param.lfs).
Note: it only extracts - if you want to modify an image you'll have to use the kernel module from the post above (or a hexeditor and some cleverness).

dunno for what the driver/partition is used, had troubles (device freeze) with custom kernel an the original module from my GT-I9100 (ICS)
as note: device boots and working without the j4fs module in initramfs...
just for fun a little patch for kernel 3.0.15, just read operation tested.

Hello all. I have built the android-ndk-r9d toolchain on my Ubuntu machine, and it will compile a few things like nmap and perl just fine with some tweaking (I forgot the links but there are projects that give the options to use when compiling these). But I haven't seen any successful compilations of more recent versions of gcc with bionic.
I did some digging around in spartacus' terminal-ide project, the point of which is to have java, vim, gcc for use on the device itself, I found that gcc was version 4.4.0. I have tried to reach him via email to see what ./configure settings he used, but to no response.
Has anyone else attempted this, to build android gcc in versions more recent than 4.4.0 for compiling software on the device? What configure settings have you tried, and how much have you modified the gcc source code itself? Or is everyone content to build other projects using their regular Linux box?
My device in question is a nexus 5, which has more than enough CPU power to do this, to quell any concerns people will have to that end.
Well, I had a day free yesterday and tried everything again, and I believe I hit the same stopping point error after correcting several others. Only this time, I made an actual script and patchfiles to handle everything to make this more organized. Again has anyone attempted to do this?
First, the script.

Second, the actual error in question.
Code:

Now, some of the patchfiles I made to fix previous errors. Is any of this recommended?

Hy guyz , i'm trying to compile ROM with uber 5.3.1 but it gave me this error:

coul'd someone help me out with it? Thanks in advance
Edit: all i need is the files i need to change to make the toolchain work , i don't care how many they are
ok , so i found out that the error is in android_frameworks_base/libs/androidfw/ResourceTypes.cpp in the line
Code:

ALOGW("Bad string block: last string is not 0-terminated\n");
return (mError=BAD_TYPE);
can someone tell me how to fix it? thx in advance
Hello! I'm not much of a ROM Developer (I can only basically merge ROM sources and device-tree) but here's the original source code from AOSP, it might help :
https://android.googlesource.com/platform/frameworks/base/+/master/libs/androidfw/ResourceTypes.cpp
Line 561 onwards is where your error is
Hope I helped and again, I'm not a professional developer so don't expect too much from me

Well it is the same line CM has to , but thanks anyway for trying at last
Most of the rom is compiling now by cherry-picking this , this and this, but now i'm stuck to this error
Code:

i guess this is the last one , hopefully someone can help me out with it
This is the problematic line is in /hardware/samsung/exynos4/hal/libhwconverter/HardwareConverter.cpp , if you remove this line , the rom will compile but i dont know if there are side efects by removeing it ...
Code:
{
SecFimc* handle_fimc = new SecFimc();
mSecFimc = (void *)handle_fimc;
if (handle_fimc->create(SecFimc::DEV_0, SecFimc::MODE_MULTI_BUF, 1) == false)
bHWconvert_flag = 0;
else
bHWconvert_flag = 1;
}
Edit: The camera is force closeing and some apps crash , all the rest works
