  • [SOLVED] Differences in Flasher/J-Link performance

    I have an older ARM Flasher debugger. Using it, I have reliable RTT/JScope plotting over a 4MHz SWD connection.

    I also have a new J-link PLUS Compact. It seems to be capable of much more throughput with an identical setup. However, I seem to get a lot of what look like bit errors.

    Timestamp goes all over the place creating unreadable charts (I had a screenshot but lost it to a BSOD)

    Without a timestamp, my floats jump to NaN and unsigned ints get giant on occasion.

    Has anyone else experienced differences like this?

  • Hi,

    Does not sound familiar.
    In general, Flashers do neither support RTT nor HSS (both J-Scope modes) so it is simulated on the PC side.
    As you observed: With much less throughput

    I do not see why timestamps and values should get corrupted if the TIF speed is the same and things are just more efficient because they are executed from within the firmware.
