  • J Link not detecting SK-MB9DF120-001

    Hi

    We have SK-MB9DF120-001 eval board and trying
    to use J-link debugger to get connected.


    When we connect Jlink and try to do a connect then we have the following error

  • Hi,

    The Fujitsu Cortex-R4 series devices need a so-called J-Link script file to make it possible to connect to the core (since a lot of special handling is necessary during connect to fully enable the debug interface).
    The script files have been written by Fujitsu and are provided by them (They should be part of the shipment).
    Did you get in touch with Fujitsu regarding this?


    Best regards
