You do mean a device driver for a disk like device?
QSSL has not released the interface specifications, and at
this time they are not giving an eta.

hi,
yeah, basically I have a block device, for which I want to write a file
system, basically I should be able to do all file operations on the device.
As a first step I have defined the device as a resource manager, and am able
to open/write etc, but now I want to be able to access it as a file system
and should be able to do operations like “ls, cd etc…”
I need to how to go about it ? hope I have made my question clear

Your question is clear, but the answer is still the same.
They haven’t released the API.

It appears what you want to do is kind of like cam-disk.so where you
would not have to deal with the filesystem structure. As Mitchell
mentioned you can’t do that since QSSL hasn’t release any info (as
it will probably be changed )
However nothing prevents you to deal with that yourself and
let you manager handles all the required request.
Depending on you hardware you may also be able to use
a flash driver (available with QNX4 cross development)

I think you’ve already beaten us in obtaining a sample of cam driver 
thanks
