I have made a os image and tring to boot from it on Neutrino650 target.
After i Reset the target machine it boots from production_boot.ifs with an error message:

Mount: can't Mount / (type qnx4)
Mount: Possible reason: Invalid argument.

How to resolve this ????
I have attached the the snapshot of the error.

Related information:
1.Target is runtime and not for debug.
2.In dev/folder their is no hdt079 file, but instead it contains hdt0179 file.
3.I dont know whether QNX4 file system can be mounted on 6.5.
4. The .build file contains 

#
# production_boot.build
#
# This boot build script is intended for production systems.
#
# How to use this file:
# Save produciont_boot.build on a target as /boot/build/production_boot.build
# Run "mkifs /boot/build/production_boot.build /boot/fs/production_boot.ifs"
# to build the boot image.  The production_boot.ifs is saved in SourceSafe
# along with the production_boot.build script.  It is included in the
# MonitorSupport.tgz by the support-tarball.sh script.
