Un-writeable file system


#1

I am trying to set up a wifi-dongle similar to the one in this similar question:http://forum.legato.io/t/wlan-usb-adapter-to-mangoh/179/3

Unlike the person asking this question, I have successfully cross compiled the driver and moved it to the machine. Unfortunately, I can’t get the file where it needs to be. In order for the driver to be recognized, It needs to be in the path: /lib/modules/3.14.29ltsi-961ca71325_ab5094eade/kernel/net/wireless/ , but this path is impossible to write to:

cp 8192eu.ko
/lib/modules/3.14.29ltsi-961ca71325_ab5094eade/kernel/net/wireless/
and I receive the error:

cp: can’t create
’/lib/modules/3.14.29ltsi-961ca71325_ab5094eade/kernel/net/wireless/8192eu.ko’:
Read-only file system

tried remounting the file system in the following ways:

mount -o remount, rw /

mount -o remount,rw /

I found other posts suggesting that the syntax was:

sudo mount -o remount,rw /partition/identifier /mount/point

So I ran:

root@swi-mdm9x15:~# mount -v | grep “^/” | awk ‘{print "\nPartition
identifier: " $1 "\n Mountpoint: " $3}’

Partition identifier: /dev/ubiblock0_0 Mountpoint: /

Partition identifier: /dev/ubi2_0 Mountpoint: /mnt/flash

Partition identifier: /dev/ubiblock1_0 Mountpoint: /mnt/legato

Partition identifier: /dev/mtdblock5 Mountpoint: /mnt/userrw

Partition identifier: /dev/ubi2_0 Mountpoint: /legato

Partition identifier: /dev/ubi2_0 Mountpoint: /home

Partition identifier: /dev/ubi2_0 Mountpoint: /legato/systems/current
root@swi-mdm9x15:~# mount -o remount,rw /dev/ubiblock0_0 /
None of these suggestions work. Every mount command returns a 0 (success) but copying files in my file system is still not working.

Is the file system totally unwritable?

I greatly appreciate your help advance!
