  • [ABANDONED] Jlink call in Jenkins doesnt exit

    Hi all,
    I am trying to set up new test station for our product on Jenkins. My first step was enabling automatic binary loading from artefacts so step for this look like this

    Java Source Code

    1. stage("Download MCU"){
    2. when {
    3. expression { params.download_mcu == true }
    4. }
    5. steps {
    6. copyArtifacts filter: '**/*Release*.hex', projectName: "Pyrrha FW/develop", selector: specific("${params.mcu_build_number}")
    7. powershell """
    8. \$hex_path=Get-ChildItem *.hex -Name
    10. "r`r`nloadfile \$hex_path `r`nr`r`ngo `r`nq" > program.jlink
    12. echo "exit `r`n" | &'C:/Program Files (x86)/SEGGER/JLink_v670c/JLink.exe' -device STM32F777NI -speed 4000 -if SWD -autoconnect 1 -CommanderScript C:/data/jenkins/workspace/pyrrha-testing_'${BUILD_NUMBER}'/program.jlink
    13. """
    14. }
    15. }
    Display All


    so basically I make new file program.jlink with sequence:
    r
    loadfile "our_tag.hex"
    r
    go
    q

    then I am trying to call JLink.exe with params listed. Problem is that JLink.exe never stops:

    Unknown command then cycle till I kill it. If I put it right to powershell window it just execute itself exit.

    any idea what I did wrong ?

    Thanks in advance!

  • Hi Joe,
    Thank you for your inquiry.

    As lines 10, 52-55 indicate, it seems like the J-Link commander cannot comprehend the commands you are trying to issue.
    Therefore, the J-Link Commander does not do anything but connect to the device and therefore also does not quit.

    Could you please provide us with the command file you are creating ("program.jlink")?

    Best regards,
    Fabian
