  • [SOLVED] SWD (2.0) Daisy Chain and the nRF52840

    Hello, we are preparing for production, we've done some searching and have hints of daisy chaining SWD targets. But have not hit with anything specific.

    Hoping someone here can me with the definitive answer to the questions

    1) Is it possible for the nRF52840 to be chained with SWD
    2) Is the J-Link capable of chaining SWD

    many thanks,
    thomas
  • Hello Thomas,

    Thank you for your inquiry.
    1: We are not aware of any Nordic device supporting SWD multidrop nor any other target device on the market.
    2: It is currently not implemented due to lack of target hardware. We recommend using JTAG which was designed for chaining and works with any target device.

    Best regards,
    Nino
