    ETM is considered the second level of debug interface. Look at the ARM specs for the purpose and operation of ETM.
    At present the Keil tools DO NOT support ETM.
    Some ARM tools support ETM with an optional purchased module plus their ADS and Multi-Ice.
    The 2138 board has the physical and electrical break out but the connector is not populated.
    If you have space on your DIY board, I suggest that you include the ETM interconnect for possible future use just as they implemented the 2138 eval board.
