Unable to open Linux Program

[Nath_SWFC]

Hi,

I work for a food manufacturing company in Sheffield and we have a machine called a duck injector which operates off a Human Machine Interface Touch Screen. The program inside this has been written and runs using Linux. This is stored on a Compact Flash Card.

This screen has been damaged and isn't made anymore so we've been sent a new screen which is a 12'1" Intel Atom N270 HMI.

I simply tried to put the Flash Card in the port and powered it up (booting from a removable source) and i get the following:

LILO 22.1 LOADING LINUX.......
UNCOMPRESSING LINUX...OK, BOOTING THE KERNEL...
cp:/mnt/flash/etc:No such file or directory
cp:/mnt/flash/var:No such file or directory
cp:/mnt/flash/dev:No such file or directory
cp:/mnt/flash/tmp:No such file or directory
cp:/mnt/flash/etc/fstab.hdd:No such file or directory
cd:can't cd to /mnt/dev
exec:sbin/init:no such file or directory
KERNEL PANIC:ATTEMPTER TO KILL INIT!


I've had absolutely zero experience with Linux so i'm completely stuck as to what to do to get it to work.

I've got a flash card with XP on it so i can boot up in that but then it won't read the flash card with the program on because it's in Linux (presumably?)

I've also tried downloading Mubuntu 10.10 and booted it up using that on a flashdrive - this allows me to read the flash card with the program but i can't get it to boot up/run.

As i say, i've got no idea how linux works, so although it probably doesn't, if this makes any sense to anyone out there and anyone can offer me any advice it would be greatly appreciated! (plus it will get my boss off my back! )

Cheers,

Nathan

Just a guess. Sounds to me the flash card was unmounted improperly and needs to have a check ran on the file system.

If you have access where you can plug in that flash drive to another linux computer which has gparted installed.

Plug in Flash card.
Open gparted.
Find flash card in gparted.
Right click on flash card partition and select umount.
Right click on flash card partition and select check. Then apply.
Let it finish.


Before starting make note of how much the flash drive was wrote to (color bar in gparted). Also file system being used (vfat,ext2,ext3,etc..) It may look full (like all yellow). This can happen on flash drives when unmounted improperly, After check see if yellow bar has shrunk.

When removing flash card. Make sure it is unmounted before removing from computer (power down is OK before removing card)

See if flash drive will boot in duck injector when done.

Edit: Forgot to mention you can do in terminal with flash card inserted into another linux computer

fdisk -l

and

df -h

You can post readout back here in code tags to show if flash drive is full (overwritten)

Thanks for the reply.

I've tried that and i still get the same errors when it's trying to boot up.

Both colour bars stayed the same after unmounting and checking and neither are full. They're both in file system ext2.

When i've checked them in gparted again they're both showing a mount point.

Not sure what you meant by the last bit?

[rokytnji]

When you ran the check. Were any errors found? What distro did you use to check the flash card also?

I am in Puppy 5.2 right now which runs as root user. So I don't need sudo or su to run fdisk -l or df -h. My example from terminal below to show what I mean by last part.

sh-4.1# df -h

Partition table entries are not in disk order

[Nath_SWFC]

No errors were found. By distro do you mean like, ubuntu 10.10?

I'm using the actual HMI Terminal, i've got ubuntu 10.10 loaded on a USB as a flashdrive so i booted it up using that. Then used system>adminstration>GParted Partition Editor.

I don't even know what sudo or su means or if i need to use them?

[rokytnji]

I have to leave. Run my own business. I'll leave you with a manual. It's in PDF. You can download and read it.

Main page - Ubuntu Pocket Guide and Reference

It will explain a lot you don't know.

If by chance, do you have another machine with the same linux OS on it?
or the company that you got the machine from my have given you a disk, or an iso file (an image of the linux operating system)
if you do have any of those you can burn it to a disk and run it "live" and install it to the flash drive.
if you have the same os on another machine you can clone the os of the working one to the problem flash drive with parted magic or Clonezilla.

PS On an unrelated subject I like the name of the town you work in . signed Sheff.....short for ,,you guessed it lol

[sgosnell]

You say you're booting from a removable source. What source? I assume it's Linux. Is it another CF, or what? How did you boot the HMI before? If you're using a different source, you will probably have to create the mount point /mnt/flash, and maybe the others, but probably not.

I'm unclear on exactly how your HMI works, and how it boots, so more information would help, if you can figure it out.

[Nath_SWFC]

Thanks for the replies.

Sheff (nice name ):

Unfortunately we don't have any machine on site with Linux on it. Also the company that supplied the machine didn't send a disk containing any linux software or iso file on it.

Some more information for yourself/sgosnell/anyone:

The Old HMI: ww.novitas.ch/Pdf/ipc/DB_en_carat_300.pdf

Information sent by the supplier when providing the above screen: img843.imageshack.us/i/duckinjinfo.jpg/

The new HMI: ww.dsl-ltd.co.uk/productspec.aspx?ProdID=AHM-6xx7

If i boot the old screen up without the CF then it says "No OS Found". If i put the flash card in it just boots up the program on the screen. In the setup the boot is set up to "Removable Sources" then "Hard Disk".

So on the new screen, i went in to the setup and boot menu then changed it to boot from removable source. Then if i boot with the CF in it gives me these messages:

LILO 22.1 LOADING LINUX.......
UNCOMPRESSING LINUX...OK, BOOTING THE KERNEL...

cp:/mnt/flash/var:No such file or directory

cd:can't cd to /mnt/dev
exec:sbin/init:no such file or directory
KERNEL PANIC:ATTEMPTER TO KILL INIT!


I thought the CF card contains everything the program needs to boot up, because on the old HMI all it needs is that card but there must be something internal configured to run this program, at a guess?

Personally, i think the old screen has been configured specially to run the program written for this machine (two german based companies) so i think we're going in circles.

The problem i've got is, this new HMI cost £1,000 whereas an upgrade for the HMI from the company who provided the machine is £4,000 so my manager wants to make this one work!
