  • [SOLVED] JLink with No connection from KEIL, but ok from JLink.exe or J-Flash Lite

    Hello,



    I was using JLink + Keil with no problem, until the following situation rise.



    Suddenly, my JLink is not working from KEIL, while it is working from JLink.exe and also from J-Flash Lite.



    So, is not an HW problem.



    Have you any tip?



    thx in advance

  • From the log output, I would say that you have either

    1)
    selected „ARM7“ under
    ProjectOptions -> Device
    in Keil.

    2)
    Or you got a „this device is unknown to J-Link“ dialog and randomly selected ARM7 there (which acts as an override and is sticky)

    To fix 1), you need to check your project settings in Keil.

    To fix 2) you need to delete the *.ini file Keil created in your project directory (where the uVision project file is located)

    PS:
    Is 50 MHz SWD speed in Keil correct? Seems quite high. Most targets cannot handle SED speeds beyond 30 MHz properly.
