  • J link J trace Keil u vision

    Do you know the difference between the debugger used by Keil uvision 4 and the debugger used J-Link J-Flash apparently Keil use J-link/ J -flash to programme the flash memory however i don't understand why you require a J-Flash license in j-fash program whereas in Keil vision we don't need it.

  • Hello,

    It is pretty simple: J-Flash is a separate software developed and maintained by SEGGER
    which has been designed for production purposes and is independent from uVision.

    The flash download functionality provided by the J-Link DLL (that functionality can also be used in uVision)
    is free of charge but it does not allow production specific steps like explicit erase, execution of post programming steps, excluding of specific flash sectors that shall not be touched, etc.


    Best regards
