  • [SOLVED] "ERROR: Specific core setup failed" connecting jlinkgdbserver to stm32f722ze nucleo board

    Not sure what I'm doing wrong here, I've connected this board the same way as all the other stm32 eval boards using SWD (3.3v, gnd, swdio, swclk, nrst). Any help is greatly appreciated, thanks!
    Here's my output running on mac osx:

  • Hi,

    J-Link V8 does not support Cortex-M7. Support for Cortex-M7 was added in 10/2014.
    Please refer to this article for an overview about the different features of each hardware version.

    Most new features are not backported to older J-Link Models after they reach end-of-life.
    J-Link V8 has been superseded by J-Link V9 in 11/2012, followed by J-Link V10 in 10/2015.
    In case you want to use the features available for current models, we recommend to use our Trade-In Program.
    It’s simple! Send us your old or damaged J-Link, J-Trace, or Flasher and receive a 50% credit of its current list cost towards a unit of equal or greater value.


    Best regards,
    Niklas
