[DISCUSSION] ExFAT file system driver - Xiaomi Redmi Note 4 Guides, News, & Discussion

Hi! So this is rather a request or a brainstorming on a certain subject but I've been testing with the available roms and kernels. For some reason most roms do not support the well known and widely used exfat file system. Even when it is supported in their kernel the system still won't see any partition that runs under exfat. No big name kernels were able to detect my exfat partition. Pixel Experience, Lineage OS, dotOS, miracle DROID, AOSP etc. None. Not even after flashing Electra Blue, Franco, Inferno and such famous kernels that said to have support. KudKernel is the only one that allows their users exfat file system usage. I dig deep into the subject and even tried to inject exfat support via sudo and scrips to certain kernels but I failed miserably. Do you think it is possible to make any kernel support exfat or just those kernels that use the latest Linaro toolchain?

The trick is to discover how KudKernel does it.

This is what's done in kudkernel

Whether or not I find out what's done in kud kernel and how does it support exfat sd card I can't do a thing about it since it'd need me to recompile and rebuild any other kernel that does not support exfat. Which is rather problematic for me, a non-ubuntu/Linux user who knows nothing about coding in that area. Ergo I'm still in the same situation I started from . -.
By the way I only get know of it today that I can't rebuild a kernel on Windows.

You are correct - you will need to build the kernel yourself. Or you can ask the developers of your favourite kernels (or ROMs) to add sdfat support. It is a fairly painless process, which would take a developer less than 5 minutes to do. Of course, they might not be interested in doing it.

Technically, yes. But you can install VirtualBox on your Windows PC, and create a Linux Virtual Machine (VM) under VirtualBox. When you boot up the VM, you are running full-blown Linux - alongside all your other Windows stuff.

[Q] want to compile CM7 - easy dev

So i would like to edit easy Dev to compile CM7 but I'm a linux newbie. I'm not afraid to admit it. Currently i'm on Ubuntu 10.10 Netbook remix, just running it off of a pendrive. How hard would it be to edit it to compile CM7 instead of CM6?

Well... You'll need a vendor tree first. And you'll have to run it on a 64-bit box with 64-bit linux. You have to change 'froyo' to 'gingerbread' in EasyDev, so it will grab CM7 source. There will also be some other differences to work out.
As soon as there's a vendor tree available and I have the time to test, I'll finish up EasyDev v7. Some of the additions that I have actually worked on so far are:
1) two or three bug fixes
2) adding CM7
3) adding option to install tiny or full gapps
The CM6 code has been unstable recently in addition to koush's hosting having issues, so I have had plenty of speed bumps in addition to real life stuff.
So... If you can wait on me, that's fine. If not, go for it! Feel free to post your code changes in the thread. We'll take any help we can get.

Conap mentioned this before as well - just out of curiosity, do you know what the dependency is that requires x64? The compilation target is an ARM device, so I can't imagine that it is a library issue... is it simply a matter that one of the compilation/build tools needs more than 3-4 Gigs of VM?
I remember that building the kernel source trees on a uniprocessor would come to a halt if you tried it on a linux box with less than about 768 Mb of RM, but hitting the 32-bit limit (3-4Gb) with build tools seems kinda surprising.

I honestly wasn't sure, but a quick Google search...
http://groups.google.com/group/android-building/browse_thread/thread/852d63ab6124c87e
This is a post from the Android Building group. It appears to be a JDK issue. I've not really tested either way as of yet, although apparently Google says "use a 64-bit host to build, that's what is supported."

Yet another custom kernel thread (special toolchain included)

Hi hackers,
i know about the common method described by chulri, to compile custom kernels and it works well.
Anyway for kernel only experiments this way is little too bloated.
EDIT3:
So here's my standalone toolchain for archos (build with modified buildroot system for 32Bit linux OS):
arm-archos GCC4.4.1 for ARM uClinux (uClibc C library 0.9.30 with Archos specific tweaks and bugfixes)
http://dl.dropbox.com/u/8815400/arm-archos.tar.gz
EDIT5:
The toolchain does not work on a 64Bit OS.
I'll post a link for the 64Bit version soon.
Only for reference:
There are a lot of external solutions to be found in the web.
E.g. there are different flavoured toolchains based on gcc 4.4.1 from Mentor Graphics (formerly known as Codesourcery):
Sourcery G++ Lite 2010q1-188 for ARM EABI (Newlib C library 1.17.0)
Sourcery G++ Lite 2010q1-189 for ARM uClinux (uClibc C library 0.9.30)
Sourcery G++ Lite 2010q1-202 for ARM GNU/Linux (GNU C library 2.11)
So if i restrict my activities on kernel compilation all three should do the job.
I made a custom kernel using the above mentioned GNU C toolchain, all compiles fine, but did not test it yet.
This is next... i need to find an easy way to test my tweaked kernels.
So far i would recommend UrukDroid running and use the recovery menu to exchange the kernel & ramdisk.
Any comments are welcome.
Unfortunately our devices use also some binary only kernel modules which are not supported by this method:
hmditx.ko (though marked as GPL, we got no sources)
hdmicec.ko (same here)
UPDATE: Sources had been published by Archos at gitorious.
nwolc.ko (proprietary module from NXP)
BTW, someone should contact the author Andre Lepine to hand out the GPL'ed source code
If i got it right, all custom kernels had been build using the buildroot system because of these.
AFAIK using another toolchain would result in a completely different system map and prevent the modules to load.
Anyway if we exclude HDMI and tweak some start scripts to prevent the modules to get loaded, we'll be fine.
Would be nice to start some discussion up here or leave a comment.
I'd also like to get some tricks form the cracks
EDIT:
Sure there's also Ti's wireless driver package which has to be integrated to compile tiwlan_drv.ko.
Need to do some research to find the correct package.
Any hints are welcome!
EDIT2:
Anyone tried to compile a gen8 kernel using the new gen9 kernel source?
Everything seems to be there...
EDIT4:
See above! The toolchain works very nice.
It had been specially compiled for external use and in the meantime it was tested on many different hosts.
Instructions how to install and use it could be found here:
http://forum.xda-developers.com/showpost.php?p=19134490&postcount=8
Thanks a lot for your attention!
Regards,
scholbert
One question: What's so much better about that toolchain to throw away the Archos-compatible toolchain and deal with the hassle of excluding features to build compatible binaries? I guess I didn't get the point

A neat little cross toolchain environment would be enough for kernel experiments.
I'm working on different platforms e.g. old Debian 4.0 workstation, Netbook with UNR 11 but limited space, other linux machines i don't like to run entire process.
You need a lot of disk space and time (at least first time to build the whole environment).
The other thing is that everything is built into the buildroot structure, you could barely locate the toolchain itself...
Sure your right, if you say everthing works out of the box, but i don't like all these automated procedures, to build my own kernel.
In fact that's just it and i wonder if there's another way.
Just kernel source + cross-toolchain...
Apart from that, the toolchain Sourcery G++ Lite 2010q1-189 for ARM uClinux (uClibc C library 0.9.30) is very close to the Archos one.
BTW, anyone tried to tweak the Archos build script to built the toolchain for external use?

Hi Scholbert!
I've been doing the same for my kernels, it compiles and runs fine, wifi loads without any particular tweak with the original Archos compiled module, but I didn't check hdmi as I don't have cable for it. I'm using a cm7 toolchain to build it (arm-eabi-4.4.3) though.

My setup is a bit different since I patched bootloader: I have my "stable" build on normal boot (/rawfs/init) and my dev build on sde (/rawfs/custom), and I flash my kernel directly from my stable build without going through recovery.
I just do adb push kernel and initrd, then directly on device a "kd_flasher -k kernel -i initrd", and I reboot from normal to sde with a "reboot_into sde". It's really quick this way, I just have a script on my linux box to do all this.
I believe you can do the same without patched bootloader with a temproot on secure archos build.

Yes, I'm playing with it. I don't know what device you have, but mine (A70S) was not finished in Archos sources: board-archos-a70s is almost empty, panel wasn't finished... I add stuff slowly (still learning Omap, I know Qualcomm better), my kernel boots, I currently have framebuffer, internal mmc and usb working.

Cool that's nice information.
Interesting that the tiwlan_drv.ko loads without problems.
Just to start an experiment, i started to shrink down the buildroot setup from Archos and built the gcc 4.4.1 toolchain only.
But it's not finished yet...

In fact there's no need for this sqashfs thing anymore...
I already got the SDE's avboot version installed. This version is little bigger in size and obviously got some add-on's.
The same byte signature could be found here, so i guess the hack would match this avboot version as well.
Maybe i give it a try.

Yes, it's the same signature, I verified it with IDA before installing sde, only location differs. You should be fine as long as you don't have multiple matches. If you want my code to patch it, let me know... You'd have to adapt the offsets but it would be probably safer than doing it manually.
Regarding kernel development, I forgot one big advantage to have patched bootloaders: ram_console! I built my "stable" and "dev" kernels with it, so I just have to make my dev kernel to crash to reboot and get the full dmesg with "cat /proc/last_kmsg" even if framebuffer or usb don't work .

Yes, gen9 sources look better for A101, I took them as base for my A70 and it's almost ok. I took away hdmi as it seems a bit too hackish, I'll see later . I also had some issue with gp timers that wouldn't use 32K clock, I'd be curious to see a dmesg on a gen9 tablet.
Right now I'm fighting with usb that kills video driver looonng way to go before having a fully functional kernel.

Ready to use Archos specific toolchain
Hi again,
three simple steps to build UrukDroid custom kernel/modules:
1. Grab my customized toolchain and install it (see first post).
The toolchain is configured to work on mostly any 32Bit linux host (min. libc 2.3.6, should work down to Debian 4.0, Ubuntu 8.04 and similar).
The toolchain must be extracted and placed at /opt on your host machine (x86).
To run it as a user you might change the properties for /opt directory to match the user's rights.
You also could extract the archive as root and run:
chown -R 1000:1000 /opt/arm-archos
To make it more comfortable:
Modify user's .bashrc file to include the path to the toolchain:
export PATH=$PATH:/opt/arm-archos/usr/bin
2. Grab UrukDroid kernel sources and compile.
UrukDroid kernel sources could be found here:
http://sauron.pourix.com/UrukDroid/UrukDroid-1.5/UrukDroid-1.5.1-kernelsrc.tar.bz2
You might extract the sources anywhere you like.
After this has been done, step into the kernel source root directory.
Modify Makefile to use the Archos toolchain (line 199):
Code:
...
# Alternatively CROSS_COMPILE can be set in the environment.
# Default value for CROSS_COMPILE is not to prefix executables
# Note: Some architectures assign CROSS_COMPILE in their arch/*/Makefile
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?= arm-linux-uclibcgnueabi-
...
cp linux.config .config
make oldconfig
make zImage
make modules
make modules_install INSTALL_MOD_PATH=/my_kernel/modules/
3. Transfer the binaries to your Archos device.
Right now there's no need to exchange the kernel, because we use $auron's base setup for the kernel.
Place your custom modules at /lib/modules
TBC

So far i tested it, the toolchain works out very nice.
Concerning kernel compilation:
It seems the binaries are quite well optimized in size. No problems so far.
I found out that in stock ROM they used some strip command to make the modules even smaller.
Anyway won't speed things up significantly i guess...
Concerning userland apps:
Though my genereated uClibc is little bigger in size, i noticed no problems so far. A binary comparison between the libaries (stock vs mine), shows little differences though.
Anyway, would be nice if people use it and report...
Have a nice day!

Wow sounds pretty like a "frankengenius" software design.
Good work!
Have you seen that Archos released part of the hdmi code as external driver code. So the kernel is even more open now (speaking of 2.6.29).
Sometimes their cooperation is very nice.
About two weeks ago i contact the author at NXP, then last week i wrote to Archos and on thursday they released it. Not bad...
Anyway they ought to release the source, even without mentioning it.
It's just GPL code.

Didn't see it, very nice! HDMI is a low on my priority list, but it's good to have source code, it will help porting it. Even though my efforts on this kernel will slow a bit as I purchased today a gen9 and ICS source code is out .
At first glance, boot process and layout looks very similar to our gen8, same rawfs, a custom file that would indicate that we should get SDE, so far so good. Need to spend some quality time with hex editor and IDA now .
Damn work, I need 72 hours days!

Hi fzelle,
Well, I'm only learning slowly, they're far more experienced than me on Archos. My main goal is to understand omap platform, that's why I'm toying with the 2.6.35 kernel. Cm7 is only a convenient for way me to make sure the kernel behaves well. I don't seek a perfect cm7/archos experience for all devices as they do, but if at some point I learned enough, I may try to help if I can.
LeTama
CM7 for Archos atm is based on the 2.6.29 kernel delivered from Archos, so your kernel is far more advanced.
And if you got 2.6.35 to work properly, the guys over at openaos would probably be happy to use that.

Yes, 2.6.35 should match better gingerbread code. If I can go somewhere, I'll share it. Currently, I'm far from that, still having troubles with usb and a big piece will be power management. We'll see, but I'm a bit out of free time.
Hey letama,
i guess fzelle is right.
AFAIK, the openaos developers concentrate on the Android part for gen8. As stated they still use 2.6.29 and this no problem so far.
But a kernel project might run in parallel.
Would be nice to get the new kernel working at least for A70 and A101.
I started a build for A101 (...and still compiling), maybe we could share our .config file
EDIT: Aaaaaargh, still fighting with the kernel config/compile errors.
Wifi/BT framework issue.... RFKILL_STATE_UNBLOCKED etc. seems not to be implemented anymore...

I made some progress there, I took LG P970 3D binaries with driver source code from their cm7 kernel (they also have a 2.6.35) and I was able to boot up to launcher. I had to fiddle a bit with audio runtime as phone audio won't work, but low level audio driver is working too. Next step is touchscreen... And probably doing a proper cm7 build, I'm running a frankenstein mix of cm7 for nook tablet

The SGX part is an open issue i guess, but there's some support form Ti as well. E.g.: https://gforge.ti.com/gf/project/openmax/frs/
Remember the Beagleboard-XM is very similar to what we got on our devices.
Also Zoom3 platform, so maybe their repository is a good starting point for these addon's as well.
In fact using the OMAP might be a benefit in general, because there are so many opensource projects covering this architecture
Happy hacking!

Agreed! It would be nice if we could develop both A70 and A101 in parallel, sharing will speed things up.

I attached my current one, I added one config option that you don't have, CONFIG_MUSB_ERRATA_445, you can remove the line. I'm not sure I have the config right, but it boots and has quite a lot of stuff working. You need to re-add A10IT board though.

Well, for me it's no longer an issue, I think what I did is the best we can do until we can get a hand on Archos binaries for 3630. The issue is that you have to have proprietary binaries, they must match driver version, and the binaries I have from P920 works fine even though maybe not as recent as Archos ones. There is no open source implementation afaik. OpenMax is only for video codec, not 3D.

To be honest i meant developing openaos and kernel in parallel. Who ever does it
Anyway, as i wrote it... i started to play around with the new kernel.
It's hard for me these days to find some time for hacking and i'm not a genius in modifying kernel drivers and stuff.
So in fact i don't know how far i will get things rollin'

How to build 2.3.7 for Nexus S
This is just a snippet that may help you.
repo init -b android-2.3.7_r1 < /dev/null (This branch is ready to use with Nexus S and Nexus S 4G)
repo sync
source build/envsetup.sh
lunch full_crespo-userdebug
make -j8 (-j8 = for eightcores like 2600k, 2630QM / -j4 = for quads 2500K/2620M/Q6600 / -j2 for dual cores / ...)

I tested a quick build. And it's working.
A virtual machine with limited RAM in order to compile AOSP? Definitively not a good idea. Why not dual boot? Sooooo easy to install the worst distro ever (*buntu).
This is awesome. My only problem is that I only have VMWare Workstation 7.
Super! Waiting for this

Dear community,
I made a AOSP developer environment for VMWare Workstation 8 or latest VMWare Player (free).
You can use this VMWare image as a base to build AOSP ROMs. Imade it for those having trouble getting it to work or maybe if you don't have time to set it up properly. Well if you are downloading this you might have a good reason!
Anyway have fun!
If there are any errors let me know.

Who would have guessed that an android dev would have difficulty setting up a linux enviroment . . . go figure.
You do not have to be an Android Dev to compile Android. I haven't written a single line of code for Android and can compile AOSP 2.3.7 fine.
This is simply to save time. And if you have good enough hardware (like myself) compiling Android AOSP in a VM session works perfectly fine.
Most people that are into computers have a rocking system. I have 12GB ram, I dedicate 8 for my VM and the rest for my main OS (windows 7). Works fine, what's the issue?
Some people don't want to dual boot and sometimes a Linux distro doesn't support certain hardware or can't be installed.
I would appreciate it. THANKS
nice.....this could be very useful

You seem to be the only one against uploading this.
Guys I am still trying to upload it. I am splitting it in 700MB sizes. Crocko's uploadservice is down. I will upload it on depositfiles and multiupload
12,5%
@FeaRThiS just stated the obvious. I also think the first step to understand how to build an AOSP ROM is knowing how to setup the development environment.
I don't have anything against using a VMWare image. But, IMHO, considering the time for uploading/downloading the file, if you do the setup yourself (in VMWare or whatever), you should have already been compiling your ROM by now.

I have nothing against it and it may even be useful in case of emergency when you can not access a linux machine, but as stated by @S suxeN the first step for any dev would be learning to create their own dev enviroment.
i didnt say that.
but the statement is right. Anyways i yet think this image is of great use, as you can always start from there, if u did something wront, what can always happen to nun-linux users.
I don't know anything about linux. Is Eclipse with ADT on here by any chance? If not, what IDE is there to develop with in this VM?
I didn't think that far. Eclipse is not installed.
But I will work on it for next release. For now you have to install it manually. I hope tomorrow evening the new vmware will be uploaded!
Hey guys, don't be so hard on the fella. He's doing us a great service in a way. Not all of us are able to bring laptops wherever we go, dual-boot, etc. I just downloaded this to my external drive that I use to keep my stuff on for work and it'll come in handy when I wanna test apps without worrying about nuking my phone.
Also, it helps that I can demo apps on the thing to co-workers on screen than using a phone. That way I won't have to worry about them screwing things up if they decided to 'explore.'
http://code.google.com/android/nexus/drivers.html#crespogwk74
Can someone help me with this? This has the binaries for the Nexus S.
Where do I place the scripts?
I have a vendor folder with several maps in it now. But I don't know what I have to do now.
I placed the 'vendor' folder in my working directory. But lunch isn't showing up crespo in the list.
These are my steps:
Building
I executed lunch. I realised I did not have crespo in the list. So next, I read the line 'Building for devices'.
Eventually I ended up here:
Building devices
Obtaining proprietary binaries
Starting with IceCreamSandwich, the Android Open-Source Project can't be used from pure source code only, and requires additional hardware-related proprietary libraries to run, specifically for hardware graphics acceleration.
Official binaries for Nexus S, Nexus S 4G, Galaxy Nexus, and PandaBoard can be downloaded fromGoogle's Nexus driver page, which add access to additional hardware capabilities with non-Open-Source code.
There are no official binaries for Nexus One, ADP2 or ADP1., ADP2 or ADP1.

I clicked the link and downloaded the GWK74 binaries.
Now then I read further:
Extracting the proprietary binaries
Each set of binaries comes as a self-extracting script in a compressed archive. After uncompressing each archive, run the included self-extracting script from the root of the source tree, confirm that you agree to the terms of the enclosed license agreement, and the binaries and their matching makefiles will get installed in the vendor/ hierarchy of the source tree.
Click to expand...
Click to collapse
I have the vendor hierarchy...
Do I have to put these files in:
my home folder/bin
OR
home folder/workingdirectory_name
Or what do I have to do now?
updated first post with small hint on how to download 2.3.7 for our Nexus S. Good luck!
yep, i think this is pretty awesome. for me, i'm not an android dev but i've dabbled with theming and porting mods from other phones to the epic 4G previously. i'd love to be able to start with a system ready to go and mess around with some guides to learn how to compile source, etc... thanks.
Nice image man, gonna give it a go later. Thought I'd put my word in the discussion , sure there lots of talented devs, but they have all got different hardware/software and time requirements. So this becomes a useful tool to add to the inventory.

Xubuntop - A full XFCE4 desktop

The stock Webtop sucks in my opinion. A outstanding concept, but poorly executed.
I'm working right now in a "revamped version" of the stock one. I call it Xubuntop - A full XFCE4 desktop.
Xubuntu is originally a Ubuntu with XFCE4 environment and some optimizations. Check the original Xubuntu project (Google it)
I'm thinking in two versions: Lightweight and Full
Lightweight: flashed in Osh and ready to go!
Full: flashed in Osh and uses Webtop2sd to expand the internal disk space.
I know that many tried to do this and I warn you guys, I'm not rediscovering the wheel. It's just a "easy way" to get those extra applications using the Xubuntu as a base.
It will feature optimizations to make the environment as lightweight as possible, giving the CPU more room to process whatever you want to execute.
I'm working two weeks on this and maybe this will be ready Saturday, but I can't promise nothing
Maybe I'll need help to make the zip to use in CWM.
So... let's go back to work
I have a questions.
Is Xubuntop for cm7/9 roms or blur/stock roms ?
Will it be dependent on the broken/outdated Motorola packages?
By this I mean, will we be able to make full use of the repos to install newer versions of software that are dependent on newer versions these packages. (E.g. the latest verision of Chromium that I can get working now is version 4 due to its dependencies breaking webtop, even when apt-get has been fixed.)

Xubuntop should work fine with the Blur and Stock roms.
CM7/9 boots the Webtop from the Webtop2sd? If yes, then I guess the "full" version can work.

In some parts, yes, it will be dependant.
My intention is to hold the core packages and add the lastest (and functional) repository with Arm support, 10.10 I guess.
The other alternative is get the source code and rebuild them in Arm architeture. This demmands a lot of work and I can't do it all by myself. But with more time and people, it can be done.
If it will run the latest available version of Chromium from the repositories (It was version 14 last time I checked) that's all I'm really concerned about. Good luck!
I guess it's impossible to squeeze a light version to fit inside the 0.8gb osh reserved space. Crap!
By the way, the system is more fluid than before. I'm trying to remove all non-essential packages right now.
With AT&T stock kernel (1Ghz) GtkPerf test run now in 13s. A huge difference.
Please give WebTop2SD a try to have a much bigger osh partition .

The system have ~1gb right now
Edit:
I'm having a hard time trying to port the lastest Chromium-browser. I need to re-install ArchLinux in my desktop first and see if I can make it work there. I'll delay Xubuntop a bit trying to port it.
I did installed xfce4 after using webtop2sd. But i ended up with a lot of stuff laying around not used, i'd like some more integrated!

Like what? aumix? Did you installed xfce4 or xfce4-desktop or even xubuntu-desktop?
I'm manually installing each software from the 'original' xubuntu distro to make sure we don't end with useless software. Is that what you want?
I'm a experienced C++ developer and I have some experience with Linux. Please let me know if you want some help.

Oh, that would be great! I'm trying to port the latest Chromium to ARM.
Do you have experience in cross compiling? I'm stucked on this...
Would this run any faster than the current webtop with xfce4 interface? My webtop functions, buts slow as hell off my sd card sometimes. Its a class 10 pny card.
Only on windows (we use windows CE and its variants at work) but let me know how we can work.

I'm working very hard to port the Chromium-browser 18.0.1025 (latest official), I've just bricked the webtop attempting to upgrade some core files... Not a problem... I was expecting this.
I'll not give up.
I broke my webtop so many times trying to get newer software to work that I just made a disk dump of a working partition that was configured how I want it. If I ever have problems, I just restore the disk dump, and within a few minutes I have everything working again.
this has me VERY excited, but XFCE still isn't lightweight enough IMHO.
What are your thoughts about Fluxbox? I remember having DamnSmallLinux on a 200mhz machine with 128MB of RAM, that was very responsive...
That said, we don't have a webtop subforum.
Which we really need, to collaborate efficiently.
Any ideas? This forum is way to frickin busy.

Someone with knowledge exfat supports

I would like to give the rom tesla 2.3 support to the microsd with exfat system try several script eh even fuse tools but I can not reach, could someone tell me how could I support this rom?

I do not know if you're asking about the contents of the ROM.
Just in case, I would like to inform you that the ROM should contain:
/system/lib/libexfat.so
/system/bin/fsck.exfat
/system/bin/mkfs.exfat
/system/bin/mount.exfat

You have not explained what you intend to do.
Do you want to compile ROM or make a ROM port?
If you want to compile a ROM, read the TeslaOS sources and direct the questions directly to Ground Zero ROMS Q&A.
