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:

Is it possible to add new commands to the system and see what is on the USB drive?
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:

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.
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.
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.
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:
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?
/dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/cf type ext2 (rw)
The SBC does not have a real time clock so the system clock is set at boot up to the default time of 00:00 1 Jan 1970 (unix epoch time). You would need to write some software to read time from the GPS receiver to set the clock.
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.
