LPC1758 ISP problems

Hi,

I am using the MCB1700 board and both Flash Magic and some software I wrote myself to try and get ISP programming working on COM0

Firstly, I am quite confused about jumpers. From reading the schematic I would say Reset and ISP jumpers need to be in but according to:
www.keil.com/.../mcb1700_su_configuring.htm
ISP jumper being on disables ISP functionality

Also no matter what I do with Flash Magic I cannot get it to work! I have exausted google and cannot see what I could be doing wrong.

With my own application I get to the point where the device sends back "Synchronized" but when I reply with "Synchronized" it then sends back a bunch of random data. Same seems to be happening with Flash Magic if I use a port monitor, after sending "Synchronized" it gets random data.

On my own application this data seems to always be the same - starting with d?

Anyone have any idea about what could be going on? Is it possible that the bootloader is corrupt?
I know the application I have written could be complete rubbish but it does respond to the initial "?"

Thanks
