I am trying to use an LPC-Link to program a custom board via a two wire Serial Wire Debug connection with an LPC1313 on it and I am receiving an error

02: Failed on connect: Em(12). System rejected access at location 0xE00FFFF4 - verify Population of memory and peripherals

The address in question varies.

I have successfully programed a very similar previous version of this board, but this one is giving me this error.  Does this suggest glitchy communications on the SWD connection? I'm gonna try to put a scope on the SWD signals.  Any other suggestions for what to look for?
