The error message indicates that the emulator uses the external memory interface to write to external memory and fail on the verify operation afterwards. 1. Do you really have external memory at adress 0xC0000 .. 0xCDFFF as your LDF indicates? 2. Do you really want to place the stack (the heap also, but that's another thing) in off-chip memory? If so, your off-chip memory (most probably SDRAM) seems to be not correctly initialized. In case of SDRAM -- did you remember to start the SDRAM controller and set wait state control in the loader?
