Editing software for STEVAL-IME009V1?

[YMakk.1]

I have just bought the STEVAL-IME009V1. It comes with a factory settings DFU file and DfuSe evaluation tool (STSW-STM32080).It generates and extracts hex files, but how can I edit those files to create impluses and burst pulses with specific frequencies?

I had the STEVAL-IME013V1 evaluation board before and it had the ultrasound pulser waveform demo, which has a very simple to interface to create pulses and upload them to board. Is contacting ST the only solution to edit these files in STEVAL-IME009V? This won't be practical at all.
