Flash magic indeed has the possibility to do this. It's probably best to verify these signals are OK, either by scope/logic analyzer, or by controlling these pins by your own.
Few questions to be able to help you better:
- Can you still access the LPC through SWD (ulink2)?
- When trying to connect to the LPC with flash magic, does the application on the LPC still run? (if so, ISP mode is not entered)
- Are you sure you've selected the right COM port?
- Are you sure the FT232 is working OK? e.g. try a loopback test by connecting RX/TX together.
- Do you get any response from the LPC when sending '?' through the terminal?
