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)
