NXPTM LPC2XXX and LPC17XX / Using the ISP on the LPC2378 should be easy....right?

Hello all:
I am having a really rough time programming with Flash Magic on a new PCB with a fresh chip. I have very limited experience with this chip.
As a summary:
Power is good, signals are good.
Scope out TX, getting data all the way to the uC.
The RST and INTO lines are being strobed as requried.
The system keeps failing the AutoBaud section of the ISP. In other words, it does not even start.
Suggestions on what I could try next would be appreciated. I even brough up a alternate PCB with just the uC, power, RS232 and control circuits with no luck. I am totally at a standstill here.
Thanks in advance for your suggestions.
