Anyone out there running the combo of Keil's compiler and JTAG with
Embedded Artists 2148 board and prototype board?  I can and have been
using Philips Flash Utility to download code to the EA boards and it
works perfectly.  

However, now that I am trying to debug software, I can't seem to be
able to debug using Keil's JTAG.  Is there a compatibility problem?  I
get 'Memory Mismatch' Errors just about every time I go into Debug
Mode.  I'm using the Keil Eval Kit Version 2.40a with uVison 3.21.  In
this instance, I'm simply trying to 'debug' the Keil sample program
'Blinky' to get a feel for the debugging process.

Here's an example Error from the loading process of Blinky.hex:

At 53% loading, the message 'Memory Mismatch', Address 0x00000118,
Value = 0x03, Expected = 0x01.  Also in the compile line, there is a
error 125: AGDI: memory write failed (0x00000118).

Is there something I'm missing on the setup?

Hi Sutton,
Please check with Keil. They have published a patch for their JTAG 
interface - it has to do with the reset signal.
I do not know if this is the problem in your case, but you should 
definitively have the patch.
Another thing to try is to decrease the JTAG clock frequency.
