Leandro, your devb-eide command looks okay (except that I
don’t think the “eide” part takes a “rw” option - that
belongs with the “blk” part if you specify it at all), so
assuming you have a properly partitioned and initialized
hard drive, you should be able to see those partitions as
writeable filesystem subtrees under /fs/, as a result of
the “auto=partition” option you (correctly) already put
after “blk”.
All the rest of your filename space, however, except for
the part under /dev/shmem, will, as Adam says, be read-only.
(You don’t have to live with the writeable space all living
under /fs, of course - that’s just the choice auto=partition
makes - you can mount your partitions wherever you like if
you don’t use auto=partition or if you umount them from /fs
before remounting them elsewhere.)

You can’t copy into the /proc/boot directory (or anywhere else except
/dev/shmem, if that is what you’re doing - and that’s not a real filesystem
anyways). If you want a full filesystem in RAM you’ll need to run either
devb-ram or devf-ram.

The mount isn’t the problem.
I have a program on the QNX machine that will gather the data from the
data aquisition card. This data will be shared via nfs.
My program in the QNX machine can’t open the file for writing. I’m trying
to create the file in any directory in the QNX. The problem is on the QNX
filesystem.
the problem is on the QNX machine. The nfs will be the problem as soon as
I solve the create file problem. >

So I gather you are trying to do the mount from Linux.
Could you please show the mount command you are using.

I have a program that read some data provided from a Data Acquisition
hardware and save the data every 5 minutes.
When the program tryies to open the file for write, the error occurs.
The nfs export will be used only to exchange the files between the QNX
and other machine running Linux.
Right now I can’t open a file for write
