LP-CC2652RB: Trouble with flashing it via XDS110 Debug using Code Composer Studio

Part Number: LP-CC2652RB
Other Parts Discussed in Thread: CC2652RB, UNIFLASH

Hi,

I have completed design of my board and the question is how to setup the circuit to program them after manufacturing.

Therefore I am now testing external XDS110 Debug Probe to flash the MCU via UART interface.

My test setup is:

  1. Remove all 8 jumpers to separate CC2652RB and the on board XDS110 from the launchpad
  2. Move the power jumper to left to External Power
  3. Use the auxiliary breakout board only on XDS110
  4. Connect following:
  • UARTRX -> RXD
  • UARTTX -> TXD
  • TGTSUPPLYOUT -> 3V3
  • TGTVDD(SENSE) -> 3V3
  • GND ->GND

The problems:

  1. If I do not connect  TGTVDD(SENSE) to 3V3; I get following error

    The value is '-267' (0xfffffef5).
    The title is 'SC_ERR_XDS110_TARGET_SUPPLY'.

    The explanation is:
    The controller could not detect valid target supply. Check target
    JTAG connection and/or connection setting specifying voltage level.

    What is the use of TGTVDD(SENSE) and where would I be required to connect it on my custom board? 



  2. After connecting TGTVDD(SENSE) to 3V3, when I try to flash my program; I get following error:

    The value is '-611' (0xfffffd9d).
    The title is 'SC_ERR_SWD_JTAG_SUPPORT'.

    The explanation is:
    A request was received to control the JTAG state or to execute a
    JTAG scan while the debug probe is in SWD mode. JTAG operations
    over SWD are not supported.

My target configuration settings are following:

The connection of my board is al below:

Please give some advice,

Thanks.
