AOSP Kernel & 64 gig sdcard

Is there a kernel that supports a 64 gig sdcard?
Or is there a mod to fix it?
Or do I have to format the sdcard for AOSP?
Please someone answer me

KT747 supports exFAT if that's what you really want. But if you're using AOSP, you can format the card as ext4 instead and use it with no problems with any kernel. I know CM10.1 supports mounting ext4 SD cards at boot (I use it), and if you're using an AOSP ROM that doesn't support mounting ext4 at boot, check out goo.im, and navigate to invisiblek's folder, and he has a zip you can flash to mount ext4 cards at boot.

Is there a filesystem supported by both touchwiz kernels and AOSP kernels?

Aside from FAT32, no. Since exFAT is proprietary, AOSP can't include it (for the most part; obviously, KT747 had it), and since 90% of users will only use Windows PCs, Samsung has no reason to support Linux filesystems.
In reality, both TW and AOSP kernels work with ext4. The root filesystem on our phones uses ext4, so the kernels have to support it. But since very few of their customers even know what a filesystem is, let alone which one they're using, Samsung sees no need to support mounting ext4 SD cards at boot. The kernel does support ext4, but Samsung went and butchered the vold.fstab so ext4 cards wouldn't mount correctly.
So, for no real reason whatsoever, FAT32 is the only filesystem guaranteed to mount in both AOSP and Touchwiz at boot without hacks (if you look around, there's a guy that's working on getting ext4 cards to mount at boot in TW). It sucks, especially with a 64 GB card.

So that is wat I thought just making sure there wasn't any ones I didn't know for linux. since I do not have a SD card reader for my PC I tried the alternative route of formatting the card through my fone that Is provided in KT747 but wen I try to put in ums mode with the app it appears on my computer as a CD drive and I can not access my card? Any thougts ?

I had that problem. My solution was to toggle USB Debugging. When it was off, turning it on fixed the problem. When it was on, turning it off would fix it. I thought they would have fixed that by now; guess not.

Sure, if it works. I was having that problem when CM had built-in UMS, so I don't know if the problem will be the same with the app.

[Q] Cannot mount USB flash drive on rooted Fire TV

I just got a FireTV, it's rooted, on the latest pre-rooted 51.1.4.1_514013920
I've tried to mount a few USB flash drives (16-64GB, NTFS or FAT32 formatted) via a USB hub and directly plugged into the USB port on the AFTV. I can't get it to work. I'm using the latest version of StickMount installed from the Google Play Store and also tried adbFire the USB mount option.
StickMount doesn't do anything and if I try to click Mount or Unmount again it says the service is busy.
adbFire shows a /usb/drive1 via SMB but it's empty, it's not the actual flash drive.
How do I troubleshoot this? I must be missing something simple.

hi you could try Busymount: http://forum.xda-developers.com/fire-tv/development/busymount-v1-0-t2920146
which mounts the drives on boot, much better than stickmount and can be customized to your needs.
Uninstall Stickmount first though as i think they conflict.

Thanks, I'll give that a try. I should also try to see first if I can see the USB flash drive from CWM, it will at least tell me everything is fine from a hardware perspective.
I installed BusyBox via adbFire, is there some other version of BusyBox required? BusyMount says it comes with BusyBox but I'm not sure whether that means it replaces any existing BusyBox or it installs its own version for its own use.

Also, what is the recommended format for external flash drives for best performance, to be writable and to be able to use from CWM to flash new ROMs, etc.? ext4, FAT32? Does it matter?

im not sure what formats work best but it depends on the type of files. Ive always used NTFS for big drives and FAT32 for flash usb.
and i installed it via adbfire also, think that is all u need.

Note II GT-N7100 READ NTFS USB OTG

Dear friends I searched a lot but could not get a clear answer to this topic. For some it works for others its NO. Along with a lot of other confusions.
But I got it working. How, here it is.
You need (what I had)
Rooted Note 2 (7100)
SELinux Mode Changer
Paragon exFAT, NTFS & HFS+
After installing these, reboot device and SElinux changes to permissive automatically. Just verify manually. Insert a NTFS partitioned USB drive to device with OTG cable. Open paragon you installed earlier. Press mount (automatically). Mounted drive ? Yes, then OK. Otherwise press manually. It will show a mount path. Just check whether the destination folder exists otherwise create it. Try mounting again manually. All done. In my case mount was at mnt/usb1, where I had to create usb1 manually.
Enjoy you NTFS drives on N2. Thanx.
I flashed DN4 V2.1

[ROOT need] Google Pixel C support OTG disk with exFAT format！

OEM firmware of Google Pixel C was just support OTG disk with FAT32, & NTFS, not for exFAT.
So we are need root by SuperSU. (SuperSU only, not kingroot or otherwise......)
Step1. Root your Pixel C. (Thank @cheep5k8, http://forum.xda-developers.com/pixel-c/development/root-modified-flashable-stock-kernel-t3289357).
Step2.Go to Play store, DownloadAPP："Paragon NTFS & HFS+" and "[root] StickMount"
Step3. Run Paragon NTFS & HFS+, then you could ignore it. (But Not uninstall it！)
Step4. Run StickMount,Let it download！
Step5. You can download ES file manager~
When you finish, your device can read/write OTG disk with exFAT. (It mount on /sdcard/usbStarge/***)
PS1：If you get notificaion that tell your OTG disk is destory or not support this format, just ignore it.
PS2：If you install StickMount only (not install Paragon NTFS & HFS+), you will lose exFAT supported when you reboot device！
Don't ask me why！Because i don't know, too！

It works

king??

kingroot is not work

Any hope for Linux file systems?

I've never tried it, but support shouldn't be needed, you'd probably have to mount it manually though.

Any way to get NTFS USB OTG working in 9.0 Pie?

Wondering if anyone has managed to figure out a way to get this working, or if I'm just missing something. I've tried everything I can find online, including a custom kernel (EX), (both) paragon NTFS mounting utilities, stickmount, a couple different TWRP-flashable .zip's, as well as miscellaneous other root apps that supposedly will mount NTFS, all to no avail.
Running 9.0, stock rooted + EX kernel and Magisk. And unfortunately FAT32 or other formatting isn't an option in my case. Any thoughts or advice or is this just a no go? Thanks!

Android doesn't support NTFS and is unlikely to ever support it. If none of the apps you've tried work then there isn't anything you can do except format the drive you want to use as FAT32. I know that isn't an option, but you don't havr many options here.

Paragon "works", but only in a couple of specialized file managers. There's no generic solution I've seen that simply mounts OTG as a directory. There is a Magisk package that claims to do this with vold, but it's only supported by an older Magisk version and doesn't support Android 9 yet.

Android only supports FAT32/Ext3/Ext4/exFAT. Why is FAT32 not an option? It will support up to 2TB partitions and although it doesn't natively support encryption, it is possible to encrypt data on a FAT32 formatted partition. What is it you are trying to accomplish?

The OP likely has a device formatted as NTFS and doesn't want to go through the trouble of pulling off the data, formatting, and replacing the data. Unfortunately for him, he's going to have little choice but to fornat to be able to use it.

exFAT USB drive wasn't supported on my P2XL Pie, tested a few days ago. Had to format FAT32 through Android (since the only options were FAT32 and NTFS in Windows File Explorer).

i may be a little late to this thread, but
total commander from c. ghisler and
usb stick plugin (tc) from ferenc hechler
does that. it worked on Android 8 at least, on android 9 i have some troubles atm, i can only copy data to my expandable sd card storage, but maybe it's a bug on my hand, worth a shot.
there is a free version of the usb stick plugin as well and total commander was always free without ads
