Hi All,

We are facing issue when tried to write contents into USB connected to BF527

from windows PC shared via SAMBA.

We used the following command to mount the USB

root>mount -t vfat /dev/sda1 /mnt/usb

we created following folder hierarchy

/var/lib/locks

Following files were put in folder /etc/config/

smb.conf

inetd.conf

Following files were put in folder /etc/

inetd.conf

services

Path "/mnt/usb/music/" was shared as samba path - we were able to browse through the contents

from a windows PC using the device IP(smbshare), but when tried to write some thing we get error.

Content of file smb.conf

***********************

[global]

workgroup = BFIN-WORKGROUP

server string = blackfin

security = share

dns proxy = no

[smbshare]

path = /mnt/usb/music/

writable = yes

guest ok = yes

guest only = yes

create mode = 0777

directory mode = 0777

Content of file inetd.conf

telnet stream tcp nowait root /bin/telnetd

Note:

1. Instead of USB if any romfs folder is shared over the network

then we were able to read as well as write.

2. We changed the permission of folder shared (chmod 777 folder name) -

but this wasn't allowed by embedded linux when tried to do the same to

USB mounted folders.

Help us in solving this USB samba write issue.

Regards

Hari

What error does it give you when you do a "chmod 777 /mnt/usb"?

We didn't get any error. The command returned but the properties where not changed.

focus on getting samba working *before* trying to mess around with USB

so change the path to just /mnt/ and do not mount the USB drive

Dear Mike,

Samba as stand alone is working fine when shared any romfs folder. We have problem only with USB and especially when writing into it alone. Changing file properties using chmod 777 for USB file or folder is not working.

@Robin,

We didn't get any special error/message after mount command

root:/> mount -t vfat /dev/sda1 /mnt/usb

root:/> cd mnt/usb/

i was workiin with hari...

mike - we didn't mess around with the usb *before* getting samba to work properly ...

samba works fine and we are able to - browse , transfer , modify etc - contents shared on the board and also change the file permissions...

the problem arises only when usb is shared through samba...

is it becos of the permissions set durin mount...

we are also able to transfer files from the board to the usb

eg- cp 1.txt /mnt/usb works fine...but even in this case we cannot change the permissions of the file after transfer

chmod 777 /mnt/usb/1.txt doesnt work....thers no error...but the permissions do not change...

you're using a FAT filesystem. there is no such thing as file permissions, so it makes no sense to try and change them. either use a real filesystem (like EXT3) or dont try and muck with permissions/owners.

I didn't say "mount -t vfat /dev/sda1 /mnt/usb" - I said "mount". What is the output of "mount"?
