QNX: mount efs

Hi all!
I create efs-image use mkefs:

mkefs my_efs.bld my_image.efs

Can i mount this image?
In QNX possible to mount the image, such as img, using the following commands:

devb-loopback blk cache=128k,auto=none loopback fd=/tmp/q4.img mount -tqnx4 /dev/lo0 /q4flash

But mount attempt efs image fails, because i can’t specify type filesystem for efs in mount command.
How i can mount this image?

I’d love to know that too…

I think what you need to do is use devf-ram to create a RAM drive that simulates Flash Memory.
I’ve personally never done this but reading the doc’s for:

qnx.com/developers/docs/6.3. … f-ram.html

seems to indicate this is what you need to use.

At this link look at the ‘transferring an image to flash’ section where they have the following:
