While launching the Universal Debug Engine (UDE), the connection to the
target system cannot be established. What may be the reasons ?
General mistakes: - wrong interface cable used
- wrong Universal Access Device connector used
ASC bootstrap loader Monitor Interface: - Possible Reasons for Communication Errors
- power supply fails
- ASC bootstrap loader mode in the target system not selected (if applicable)
- target not in RESET/Bootstrap loader mode
- wrong target configuration file used when launching UDE
- no external RAM for the monitor available
- no external RAM for the interrupt vector table available (0x0000 to 0x01FF)
- selected baud rate overruns external hardware
- Additional Diagnosis:
- Using
the MiniMonitor Interface the diagnosis capabilities of the debugger
are made available if external RAM access does not work at all.
ROM Monitor Interface: - Possible Reasons for Communication Errors
- power supply fails
- bootstrap loader mode is selected
- wrong target configuration file used when launching UDE
- ROM content not correctly programmed
- no external RAM in the monitor data area available
- selected baud rate overruns external hardware
