Mount USB on a hardware device - BusyBox 1.0
hey there everybody,
I m having lots of trouble with a TS-7260 Single Board computer that is somehow equipped with a small UNIX version for hardwre devices called BusyBox v1.0. This device is hooked up with an old accelerometer and a GPS Engine in order to log seismic events. Since I got this acquisition system as a present, I have wether README files nor manuals on this and I may not change any settings or pre-installed operational systems. the thing is, that a usb flash drive is hooked up to the ts-7260 board but I donīt know what is on there since canīt mount it or read it with any other OS. If I am logged in via ssh and try to mount it with $ mount -t vfat /dev/scsi/host0/bus0/target0/lun0/part1 /mnt/cf/ as suggested in a really old manual I get an error like this: mount: Mounting /dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/cf failed: Device or resource busy All commands that are available on BusyBox v1.0 are listed bellow: Built-in commands: ------------------- . : alias bg break cd chdir continue eval exec exit export false fg hash help jobs kill let local pwd read readonly return set shift times trap true type ulimit umask unalias unset wait [ addgroup adduser adjtimex ar ash awk basename bunzip2 busybox bzcat cat chgrp chmod chown chroot chvt clear cmp cp crond cut date dc dd deallocvt delgroup deluser devfsd df dirname dmesg dpkg dpkg-deb du dumpleases echo egrep env expr false fbset fdisk fgrep find free ftpget ftpput getty grep gunzip gzip halt hdparm head hostid hostname hwclock id ifconfig ifdown ifup inetd insmod install kill killall klogd ln logger login logread ls lsmod makedevs md5sum mkdir mknod mkswap mktemp modprobe more mount mv openvt passwd pidof ping pivot_root poweroff ps pwd reboot reset rm rmdir rmmod route sed sh sleep sort start-stop-daemon strings su sulogin swapoff swapon sync syslogd tail tar tee telnet telnetd test tftp time touch tr traceroute true tty udhcpc udhcpd umount uname uncompress uniq unzip uptime usleep vi wc wget which whoami xargs yes zcat Is it possible to add new commands to the system and see what is on the USB drive? Thanks a lot folks and greetings from Chile |
What is the output of "fdisk -l"?
|
$ fdisk -l

The TS7200 should be similar to the 7260 and by default the USB modules are not loaded. Try running loadUSBModules.sh. Once the script completes the device ID for the USB drive should be created and you can then mount it.
Also make sure your not actually in the /mnt/cf directory when trying to mount the drive. |
Thanks alot for your advice. But this is what I get:

Not familiar with SB, but was is the output of the mount command (without arguments)?
|
$ mount
/dev/root on / type yaffs (rw) none on /dev type devfs (rw) proc on /proc type proc (rw) /dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/cf type ext2 (rw) |
Also look at the output of the dmesg command to see if there are any other error messages.
P.S. Good call Wim Sturkenboom it or some other device is already mounted. |
Hey Michael,

No problem. So have you looked at the /mnt/cf directory to see what is there? If it came with the board I suspect it is the development system which should be debian. It is a complete OS but does contain the headers etc so you can compile programs for the SBC.
All of the documentation is on line at http://www.embeddedarm.com/products/...oduct=TS-7260# |
Moved: This thread is more suitable in Linux - Embedded and has been moved accordingly to help your thread/question get the exposure it deserves.

The /mnt/cf/ only contains one folder, where the ring buffers and current acquired data of the accelerometer are stored.
I can also look them up even though the USB hard drive is not mounted (or hooked up). I ve no clue what this drive is good for since everything seems to work without it as well. |
Ok, that clarifies things a bit.
Is the data acquisition software configured to write to /mnt/cf/folder? It appeases that even if the drive was not mounted the software will still write to the same destination directory and the only difference is it will be written to the on board flash memory instead of the USB drive. The flash memory isn't very big which is why you would want the USB drive. Since the flash memory is formatted as ext2 windows cat not read it without additional software. http://www.howtoforge.com/access-lin...s-from-windows Just out curiosity do you have any information on the accelerometer like make or model number? |
thanks a lot! I could figure out from the directory structure that the acquisition software is calles SEISLOG but I can't start it because the commands are not supported by the OS. Nevertheless I think it writes data automatically in the /mnt/cf/ folder and triggers itself. the thing I don t understand is, why there is a USB hooked up to the system. the folders on cf are not really big so it s possible, that theyre stored on the TS-7260:
$ du -h 7.0k ./cf/SLG/RNG/PU_SE/2012/08 7.5k ./cf/SLG/RNG/PU_SE/2012 2.5k ./cf/SLG/RNG/PU_SE/1998/01 3.0k ./cf/SLG/RNG/PU_SE/1998 11.0k ./cf/SLG/RNG/PU_SE 7.0k ./cf/SLG/RNG/PU_SN/2012/08 7.5k ./cf/SLG/RNG/PU_SN/2012 2.5k ./cf/SLG/RNG/PU_SN/1998/01 3.0k ./cf/SLG/RNG/PU_SN/1998 11.0k ./cf/SLG/RNG/PU_SN 7.0k ./cf/SLG/RNG/PU_SZ/2012/08 7.5k ./cf/SLG/RNG/PU_SZ/2012 2.5k ./cf/SLG/RNG/PU_SZ/1998/01 3.0k ./cf/SLG/RNG/PU_SZ/1998 11.0k ./cf/SLG/RNG/PU_SZ 2.3M ./cf/SLG/RNG/PUC1_SHE 2.2M ./cf/SLG/RNG/PUC1_SHN 2.3M ./cf/SLG/RNG/PUC1_SHZ 6.8M ./cf/SLG/RNG 1.0k ./cf/SLG/EVT/1998/01 1.5k ./cf/SLG/EVT/1998 10.0k ./cf/SLG/EVT/2012/08 10.5k ./cf/SLG/EVT/2012 941.5k ./cf/SLG/EVT 7.7M ./cf/SLG 7.7M ./cf 7.7M . the data is acquired by a modified SSA-2 by Kinematrics accelerometer. btw, I use a mac to connect to the ts-7260. how do you know, that the flash drive as ext2 windows? for me it is really important to make a copy of the usb stick and know what is on there. btw: the system is triggered by an external gps antenna. nevertheless ewhen I type date: it says $ date Thu Jan 1 02:27:49 UTC 1970 nevertheless, the data has the correct date as a name but the wrong time stamping so I guess the CPU clock is not connected with the GPS. do you know how I can syncronise them as well? |
From the output of the mount command.

The on board flash memory is only 32MB so the OS and the data acquisition software would reside there but the logs could fill it up which would not be good which is why you want the USB drive. |
