How to mount ext3 on Memory Card ?

[kundancool]

In your fw (cramfs-root-CG43/dev) only have mmc and mmca1.

well now I have managed to mount my ext2 partition on phone

do like this

#!/bin/bash
modules_dir='/mmc/mmca1/modules'
device_path='/ezxlocal/mmca2'
mount_path='/ezxlocal/download/mystuff/MMC2'
#loading modules
insmod $modules_dir/loop.o
insmod $modules_dir/jbd.o
insmod $modules_dir/ext2.o
insmod $modules_dir/ext3.o

mknod $device_path b 243 2
chmod ug+rw $device_path

mkdir -p $mount_path
mount $device_path $mount_path

this should work for you

but I am unable to view files in file manager

but Ekonsole shows files

your script loads modules successfully, but nothing happen.
After then, I try
mount /dev/mmca1 /ezxlocal/download/mystuff/MMC2
so, it works. I connect my mmc to Window PC via MemoryCard Reader, Window shows my mmc (mmca1 - Linux ) like a FAT partition. (

because, the File Mgr can't view files, so I reformat my memory card, like this :

Disk /dev/mmca: 2059 MB, 2059141120 bytes
255 heads, 63 sectors/track, 250 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/mmca1 1 211 240943 6 FAT16
/dev/mmca2 212 242 1702890 83 Linux
/dev/mmca3 243 250 64260 82 Linux swap

and retry to mount with mmca2 is Linux partition...

I try

#!/bin/bash
modules_dir='/lib/modules'
device_path='/ezxlocal/dev/mmca2'
mount_path='/ezxlocal/download/mystuff/MMCa2'
#loading modules
insmod $modules_dir/loop.o
insmod $modules_dir/jbd.o
insmod $modules_dir/ext2.o
insmod $modules_dir/ext3.o

mknod $device_path b 212 2
chmod ug+rw $device_path

mkdir -p $mount_path
mount $device_path $mount_path

still not working what's the hell

I try
mount -t ext2 /dev/mmca2 /mmc/mmca2 -o noatime
its show
mount : /dev/mmca2 iis not a block device


the same with mount -t ext3

I try
mount -t ext2 /dev/mmca2 /mmc/mmca2 -o noatime
its show
mount : /dev/mmca2 iis not a block device

you are doing it wrong
follow the script commands carefully now I have added comments

#!/bin/bash
modules_dir='/mmc/mmca1/modules' #this is a directory where you should have all modules
device_path='/ezxlocal/mmca2' #this is not a directory
mount_path='/ezxlocal/download/mystuff/MMC2' #this is a directory where ext3 partition will be mounted
#loading modules
insmod $modules_dir/loop.o
insmod $modules_dir/jbd.o
insmod $modules_dir/ext2.o
insmod $modules_dir/ext3.o

mknod $device_path b 243 2 #creating device for ext3 partition
chmod ug+rw $device_path #giving permissions to device

mkdir -p $mount_path # creating directory for mounting ext3 partition
mount $device_path $mount_path #mounting ext3 partition

thank kundan, I has mounted, ^^ but now is new problem: Icant copy or create anything on mount_path
PS: I think I wrong when format /dev/mmca2, Could you tell me how to format it correct ? I have a Ubuntu OS.

[MarkDark]

on Ubuntu i try
mkfs -t ext3 /dev/sdb2
to format my mmc to ext3 type
then I insert it to phone and run your script. Its working but I cant do anything on it please help.

Congrats now you can mount you device well I think you must use "Gparted" to format your card and create partition it is best way to manage disk I use it
install from software centre on Ubuntu

on Ubuntu i try
mkfs -t ext3 /dev/sdb2
to format my mmc to ext3 type
then I insert it to phone and run your script. Its working but I cant do anything on it please help.

well I have not yet tried to add data to it I have just mounted it just to show you
I will try and let you know if I can add/edit data on ext3 partition

[MarkDark]

Solved !
We need run as root to do everything on ext3 partition,
and sets root for our applications to working easy on it.
Thank kundancool so much ^^

good to know you managed it to work
well since you did most of the thing in root
like applying permissions mounting and creating things that may be the reason why it needs root
