ntfs support problem of ssd on imx6 sabresd board

[kaisun1]

Hi ,

     I am using imx6 sabresd board as my development platform, using android 4.0 as my operating system.  I've added some code, now my board can recognize fat32 format ssd, and can read and write properly.  Now I need to used ntfs format but the code does not support. 

I usd the patch(0004-ntfs_support.patch ) on HDMI Dongle Reference Design Release

adn used the folder (cp folder external/ntfs-3g) on i.MX6 OTT TVBox HW/SW Reference Design Release (ICS4.0.4_1.0.0-alpha)

but my board can not recongnize ntfs foramt ssd.

Does anyone know if this knowledge, or give me some advice. Thank you very much for any help

regards

when i compile all projects. it is error :

external/ntfs-3g/src/ntfs-3g.c:69:23: error: sys/xattr.h: No such file or directory

It was answered in https://community.freescale.com/docs/DOC-94561.

To support NTFS, except the "external\ntfs-3g", "system\vold" should also be updated.

Hi li :

        i know why it happen. because when i copy the ntfs-3g to /external/.  i read the README.and do the follow operation according to the README.

cd external/ntfs-3g

./configure

make

cd /myandroid

make

now i had obtain the system.ing and boot.img .i will used the ntfs format ssd.and test whether it works.  when i open my terminal .I put the Log on attachment.

d--------- system   system            1970-01-01 00:00 sata

d---rwxr-x system   sdcard_rw          1970-01-02 00:00 sdcard

this is my change :

1.	system/vold/Andrido.mk

Fat.cpp \

+        Ntfs.cpp \

Loop.cpp \

2.	add /sys/vold/Ntfs.cpp file
3.	add /sys/vold/Ntfs.h file
4.	change system/vold/Volume.cpp
5.	change device/fsl/imx6/imx6/mk

+	PRODUCT_PACKAGES += \
+	ntfs-3g                                \
+	ntfsfix

6.	kerenl_imx/arch/arm/configs/imx6_android_defconfig

        +CONFIG_FUSE_FS=y 

7.	add the /external/ntfs-3g  file

You had used the wrong way to build the source code, the readme file is not for Android.

In Android, you should use the followed commands:

$ export ARCH=arm

$ export CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

$ cd ~/myandroid

$ source build/envsetup.sh

$ lunch sabresd_6dq-user

$ cd external/ntfs-3g

$ mm

I think you had never built your android code, please followed the Android BSP user guider to build the Android code first.

Hi li:

      I deleted my out/target/product/sabresd_6dq directory and recompile generated sabresd_6dq/system.img file. Then I went to / external/ntfs-3g this directory, I do the command output:

sk@ubuntu:~/myandroid/external/ntfs-3g$ ./configure

[qiang_li-mpu_se · Accepted solution]

Please delete your corrent "ntfs-3g" folder and unzip a new folder here.

Please don't run "sk@ubuntu:~/myandroid/external/ntfs-3g$ ./configure " at any time, it is for Linux, not for Android, this command will modify some head files for Linux build, so it will fail to build the code in Android.

I attached the build steps again, after finished building the sabresd image, please follow them one by one, don't skip any line or add any line, thanks!

$ export ARCH=arm

$ export CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

$ cd ~/myandroid

$ source build/envsetup.sh

$ lunch sabresd_6dq-user

$ cd external/ntfs-3g

$ mm

Also attached the workable "ntfs-3g.tar.gz" here, hope there will be no more stange things happen in your side again.

HI li,

      now i can use commond "ntfs-3g /dev/block/sda1  /mnt/sata" and use mouse click "Mount SD card "button .then ssd is mount.  How do  make it automatic mount ？

[qiang_li-mpu_se]

sata hot plug feature was not supported yet, you need connected the sata before power on the board. Then after run into android, it can be mounted.
