Default configuration of the utility installs binaries of evaluation demo. For IPNC you need to edit config file. Please read carefully manual without panic.
Just to add to above point.
In IPNC 2.5 Release we have attached latest Package for IPNC DM36x SD boot with updated binaries. The package contains 'sd_boot_readme.txt' which gives you procedure of how to update the SDCard appropriately.
