Havig problem with elfpatch (lockbox security)

1. Hi.

I'm having problem with elfpatch too. I'm using Visual DSP++ 5.1.2 which elfpatch is in this address: "F:\Program Files\Analog Devices\VisualDSP 5.1.2"

When I want to extract the contents of the message to be signed from the secure_function.ovl file with elfpatch, it crushes and does nothing. This is the command I use:

elfpatch.exe -get _ov_overlays_1 -o secure_function.bin \secure_function.ovl(overlay1.elf)

Also when I run the example in this folder: "F:\Program Files\Analog Devices\VisualDSP 5.1.2\Blackfin\Examples\ADSP-BF548 EZ-KIT Lite\lockbox" elfpatch isn't responding.

It seems that elfpatch isn't working and unfortunately there isn't anything else to use instead of elfpatch.  

Thanks for your help…
