JTAG Lattice CPLD flashing

I'm very new to JTAG, urJTAG, and ISP for these types of chips.

I've been given the following:

• Arcom Viper dev board with Windows CE (OS on PXA250) running the Eboot (bootloader on LC4128C)
• Blackhawk USB100v2 JTAG Emulator
• CD with board documentation & reboot .bin files

Have been asked: if I can convert this to run the linux bootloader (redboot) and OS.

To do this I made the initial assumption that I have to get redboot flashed to the Lattice LC4128C. So I took a look at urJTAG which seems to detect the chips fine, I'm just a total noob when it comes to what I should be seeing, and where I'm going wrong.

I've gone as far as to attempt the following, but haven't got any positive outcome thus far, and feel like I'm missing something that I can't seem to track down. I see reference to SVF, JEDEC files, and potentially the need to know the address offset for something like this, but can't quite put it all together, and these boards are no longer supported, the Arcom company has basically been bought out and offers no assistance.

Current Attempt:
