You are probably barking at the wrong tree ;-)
The bootloader you refer to is residing in the PSoC4 chip and not within the 5-LP. I am not sure if the PSoC5 on the Pioneer Kit even has got a bootloader, afaik it is programmable only by using a MiniProg3 or something equivalent.
Since the PSoC4 has got no USB interface you are a bit stuck. Next bigger solution is a kit-050 for $100 which is more than that what I spend for breakfast.
hopefully somebody else has got a different idea
Bootloader for the 5LP on Pioneer -

Thats the method i used Dana.
I can verify it works. The problem i'm having is with the usb.
Not sure if this will help......
