Hi,
i am facing the problem with devb-loopback block driver which I took this driver from qnx650 repository.
The problem is, not able to mount iso image if the image size is more than 2GB.

devb-loopback blk cache=256k,vnode=128,automount=lo0:/mnt/swdl:cd loopback ro,blksz=2048,fd=/fs/usb0/swdl/swdl.iso

After giving the above command, I am getting following error  

devb-loopback: unable to open '/fs/usb0/swdl/swdl.iso' - Value too large to be stored in datatype.
Below is the use info of the devb-loopback which I am using 

 

NAME=devb-loopback
DESCRIPTION=Loopback (fd-based) block driver
DATE=2010/07/09-13:54:19-EDT
STATE=stable
HOST=mainbuild
USER=builder
VERSION=6.5.0
TAGID=89

I googled about above error and found that some of the drivers/libraries/APIs not support to open the file if the size 
is more than 2GB.

I would like to know about,

1. Does devb-loopback support to open large files?
