  • [SOLVED/OR] Is there any possible to specify all the parameters of JLinkRTTLogger.exe at command line?

    Hi
    I want to write a batch file to automatically record all the rtt logs for several devices simultaneously
    But I don't know How to specify all the params and select the specific jlink via command line.
    Can anybody help? :)

  • Hi,

    currently, there are no command line options for RTT-Logger.

    As an alternative, J-Link RTT-Client can connect to an open session, which can be created via batch-file (e.g using J-Link Commander).

    Best regards,
    Niklas

    HI Niklas,
    very appreciate your help.
    Would you please share a little more about how to write such a batch file?
    Or is there any reference code I can study with?

    thanks

  • Hi,

    Example procedure in order to open a connection to J-Link and then log RTT-Output:

    1. Open a connection to J-Link and let the J-Link connect to the target device (In this case, a Freescale K66)
      Example:[quote]"C:\Program Files (x86)\SEGGER\JLink_V510f\JLink.exe" -device MK66FN2M0xxx18 -if SWD -speed 12000 -autoconnect 1 -SelectEmuBySN _InsertSNofJ-Link_ [/quote]You need to adjust installation path and target device. Adjust target
      interface and and speed if necessary. If you have multiple J-Links
      connected to your PC, you can select one by passing the -SelectEmuBySN
      parameter.

    2. Open J-Link RTT Client and redirect stdout.
      Example:[quote]"C:\Program Files (x86)\SEGGER\JLink_V510f\JLinkRTTClient.exe" > C:\temp\rttclientlog.txt
      [/quote]


    A list of available J-Link Commander options can be read by typing "?" in J-Link Commander or by consulting UM8001 (chapter 3.2 "J-Link Commander" and chapter 12 "RTT")

    Hi Niklas,
    Thanks again very very much for your great support.
    I still have one question, Can I run multi pair of JLink.exe and JLinkRTTClient.exe simultaneously on the same computer?
    If I can, How can I Know which JLink.exe the JLinkRTTClient.exe currently connected to.(seems all the JLink.exe listen to the same tcp port 19021)
    Is it possibly that I name the log file according to the JLink SN?

  • Hi,


    If I can, How can I Know which JLink.exe the JLinkRTTClient.exe currently connected to.(seems all the JLink.exe listen to the same tcp port 19021)

    The port will be customizable in a future version of the J-Link software & documentation pack.
    Until then, only one RTT-Telnet connection per Host-PC (or VM) is possible.

    Is it possibly that I name the log file according to the JLink SN?

    This could be done using Batch variables, example:

    Source Code

    1. @echo off
    2. for %%i in (1,2,3) do (call :subroutine %%i)
    3. pause
    4. :subroutine
    5. echo %1
    6. GOTO :eof

    Best regards,
    Niklas
