exFAT - arm linux

source code : exFAT-nonfuse
https://github.com/dorimanx/exfat-nofuse
http://opensource.samsung.com/reception/receptionSub.do?method=search&searchValue=exfat

[Installing as a stand-alone module]
make
sudo make install

 To load the driver manually, run this as root:
modprobe exfat

 You may also specify custom toolchains by using CROSS_COMPILE flag, in my case:


CROSS_COMPILE=../dorimanx-SG2-I9100-Kernel/android-toolchain/bin/arm-eabi-

[Installing as a part of the kernel]

Let's take [linux] as the path to your kernel source dir...
cd [linux]
cp -rvf exfat-nofuse [linux]/fs/exfat

 edit [linux]/fs/Kconfig
 menu "DOS/FAT/NT Filesystems"

  source "fs/fat/Kconfig"
 +source "fs/exfat/Kconfig"
  source "fs/ntfs/Kconfig"

 endmenu

edit [linux]/fs/Makefile
  obj-$(CONFIG_FAT_FS)    += fat/
 +obj-$(CONFIG_EXFAT_FS)  += exfat/
  obj-$(CONFIG_BFS_FS)    += bfs/
cd [linux]
make menuconfig

 Go to:


File systems > DOS/FAT/NT check exfat as MODULE (M) (437) Default codepage for exFAT (utf8) Default iocharset for exFAT

ESC to main menu Save an Alternate Configuration File ESC ESC

build your kernel

1./linux kernel xxx/fs/exfat/ 下產生 exfat.ko，將此ko拷貝到平台 insmod
2.cat /proc/filesystems
...
...
...
exfat => successful!!! 
....

3.mount -t exfat /dev/mmcblk0p1 /mnt/sd_card

1) Download the "exFAT" moudule linux driver from the below link.

https://github.com/dorimanx/exfat-nofuse

2) Modify the "Makefile" as per your kernel source.

3) Build with your tollchain

4) Install the "exFAT" driver in linux.

Linux 下使用 exfat 檔案系統

 要掛載使用 exfat 檔案系統的磁碟，mount 時候指定 exfat 格式即可。其操作命令如下：

   mount -t exfat /dev/device-name /mnt/dirname

  要格式化某個磁碟裝置使用 exfat，可以透過 mkfs.exfat 命令。其操作命令如下：

   mkfs.exfat /devv/device-name
