  • [SOLVED] Combining JLink Script and Commander command Script

    Hi,

    I am trying to make a batch script for daisy chained JTAG boards. What I want to do is automate the flashing of all the boards in the chain successively using a single script.

    Reading UM08001 Jlink document, what I have understood so far is that I need to give the special initialization parameters in a Jlink script file (which looks similar to C) and then use the JLink Commander commands like 'Loadbin' to flash the board.

    Could someone explain me how to combine/connect these 2 into a single batch script for my purpose OR if you could suggest an alternative to achieve the same?
    Thanks in advance.

  • Hi,

    give the special initialization parameters in a Jlink script file (which looks similar to C)

    If the device does not work out-of-the box with J-Link and needs special initialization, this is correct.

    I would suggest the following:

    I. A Windows .batch / Linux .sh file, which calls J-Link Commander multiple times:

    Source Code

    1. call JLink.exe -JLinkScriptFile ${path to script file for Device A} -device ${Name of device / core} -if ${target interface, like JTAG/SWD} -speed{target interface speed in kHz, e.g. 4000} -autoconnect 1 -CommandFile ${path to command file for Device A}
    2. call JLink.exe -JLinkScriptFile ${path to script file for Device B} -device ${Name of device / core} -if ${target interface, like JTAG/SWD} -speed{target interface speed in kHz, e.g. 4000} -autoconnect 1 -CommandFile ${path to command file for Device B}
    3. [..]

    II. Each command file would contain sth. like:

    Source Code

    1. r
    2. loadfile ${path to datafile}
    3. r

  • Hi Niklas,

    I just had one more doubt that I wanted to get cleared from you.
    If the device I want to flash DOES work out-of-the-box with JLink, then is there a way to program a particular device in daisy chained configuration of such devices using only commander script (without using JlinkScript) ?
    If the device does not work out-of-the box with J-Link and needs special initialization, this is correct.

  • Hi Vinay,


    good to hear that you are up and running :)

    If the device I want to flash DOES work out-of-the-box with JLink, then is there a way to program a particular device in daisy chained configuration of such devices using only commander script (without using JlinkScript) ?

    Yes, just omit the "-JLinkScriptFile ${path to script file for Device x}" parameter. If there are multiple devices of the same type in the daisy chain, you then probably need to specify the current position by adding -JTAGConf <IRPre>,<DRPre> to the JLink.exe call.
