  • [ANSWERED] JFlash on commandline with switch "/min" does not work

    I use j-link PRO to program our hardware.
    With "SEGGER J-FLASH V5.00b" everything is working fine.

    If i try to program on the commandline with "C:\Program Files (x86)\SEGGER\JLink_V500e\jflash.exe -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit" everything works fine.
    In the manual (segger.com/cms/admin/uploads/productDocs/UM08001_JLink.pdf) on page 245, i can read about a switch "/min".
    This does not work for me.
    I use Windows 7 Enterprise.

    Anybody an idea why?

    Actualy i would like to program our hardware with J-Flash and LabVIEW.
    Has anybody done so?

  • Hi,

    Just to make sure that we understand you correct with the statement below:
    In the manual (segger.com/cms/admin/uploads…08001_JLink.pdf) on page 245, i can read about a switch "/min".
    This does not work for me.
    Programming etc works but J-Flash does not start minimized? If not, please describe what does not work in more detail.

    We just gave it a quick try on a Win7 machine using the command line below:

    cd C:\Program Files (x86)\SEGGER\JLink_V501d
    start /min /wait "J-Flash" "JFlash.exe" -openprj"C:\Work\WorkSpaces\J-Flash\ADuCM3025.jflash"

    As expected, J-Flash starts minimized and the project is correctly opened. So right now, we do not see any issues / problems here.


    Best regards
    Erik

  • Hi there and thank you for your response.
    On the commandline both "systems" of commands work:
    C:\Program Files (x86)\SEGGER\JLink_V500k\jflash.exe -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit
    and
    start /min /wait "J-Flash" "C:\Program Files (x86)\SEGGER\JLink_V500k\JFlash.exe" -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit

    The first command opens the Jflash fully, and the second command opens the Jflash as desired only minimized.

    If i try to execute both in Labview with the "System Exec.vi" only the first commend (C:\Program Files (x86)\SEGGER\JLink_V500k\jflash.exe -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit) works!
    The command start /min /wait "J-Flash" "C:\Program Files
    (x86)\SEGGER\JLink_V500k\JFlash.exe"
    -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit     reacts with an error:
    Error 2 occurred at System Exec.vi. Command was "start /min /wait "J-Flash" "C:\Program Files (x86)\SEGGER\JLink_V500k\JFlash.exe" -openprjC:\temp\mb9bf517s_gt20-logic.jflash -ip10.4.4.250 -auto -exit"

    Why are there two different systems of commands, and where are they disribed fully?

  • The "start" command is a Microsoft DOS specific command which starts a process in a separate window from the command line. The "/min /wait" specifies how this window / process is opened. The "start /min /wait" is not a J-Flash related command but can be used to start any application minimized. I am not familiar with LabView but referring to the error message, it seems to me that LabView does not come with such an functionality. I can set this on our internal todo list for J-Flash to add a command line parameter (e.g. -min) which forces to start J-Flash minimized.

    For now, you should be able to create a batch file as below and execute the Start.bat from LabView:

    Start.bat
    start /min /wait "J-Flash" "JFlash.exe" -openprj"C:\Work\WorkSpaces\J-Flash\ADuCM3025.jflash"

  • Thank you Erik for your explenation about the command.
    I now understand the commands. (MS-DOS / JFLASH)

    I command "-min" in JFLASH would be great!
    We have to programm boards in big quantities and therefore use Labview to test/program the boards.
    A command "-min" would help this progress. (in case of fail...)
