  • JLink Pro (from dec. 2013) maximum speed not reachable

    Hi,
    i observed that maximum speed of my JLINK Pro is 12MHz (using JFlash utility) or 10MHz (Keil) using STM32F407VG over SWD interface (jtag looks same), same problem is with STM32L151RB
    How can i set jlink maximum speed to maximum communication speed?
    Thanks
    Peter
  • Hi Peter,

    For J-Flash: Will be corrected. Thanks for letting us know.
    Keil/IDE in general: More something for the IDE vendor to fix/change.

    But in general, for flash programming itself, you will not gain much from a higher communication speed.
    J-Link usually reaches the max. flash programming speed (limited by the flash speed itself) at 4-8 MHz.
    For debugging speed, higher communication speed makes sense of course.


    Best regards
    Alex
