Failed to execute MI command

Post port from CodeWarrior to KDS 2.0.0.

I get this when tiring to start a debugging session.


Error in final launch sequence

Failed to execute MI command:

tbreak main

Error message from debugger back end:

Cannot access memory at address 0x17bca

Cannot access memory at address 0x17bca


The only way I have found around this is to power on the K20 right before the code download begins.

Any thoughts on how to fix this?
