Hi MB,

a disk volume is mounted automatically when it is accessed, usually
throught the first open() or creat() function.

So, try ls "" to see if you can see the device.

hi Ed,

Even thou I do initialisation of ATA device in my BSP, after it brings
up, if I do devs, I dont see my device. If I call ataXbdDevCreate()
and then if I do partition using xbdCreatePartition(), then I can see
the device listed. So, with out I create a partition, my device is
not getting listed, so how should I do open() or create()?

thanks,
MB.

If your BSP is configured correctly, usrAtaConfig should be getting
called, which will then (usually) call ataXbdDevCreate. You should be
able to see your device with the devs command. So, I suspect that this
is merely a configuration issue.

If you rebuild the ataDrv.c file with ATA_DEBUG defined, and maybe
change ATA_DEBUG_LEVEL to get more debug info, this should give you a
pretty good idea what is going on.

ls "" will call the open() function.

Hi ED,

When I call usrAtaConfig(), it says instantiating rawFs, it is not
recognising the dos fs which is already formatted by linux/windows.
Later if i do LS, i am not seeing my device.

Any idea what may wrong?

I would need to see the debug output from the ataDrv.c file to be of
any further help, except to say that the rawFs is getting instantiated
because a call to fsmProbe() is returning an error, meaning that
vxWorks cannot detect the filesystem. Perhaps you can reformat the
file system in a different way, or get vxWorks to format the file
system?

I have had problems with ATA controllers in the past but can't do much
more without a detailed investigation.

Contact me directly if you need this.
