  • [SOLVED] cannot connect to X server

    I migrating to Segger Jlink PLUS compact and setting up a CI pipeline that uses jflash. It looks like Jlink GDB server has a command line utility but not so for J flash. What is the simplest way to run jflash headless? Surely this is very basic functionality that is provided somehow. Using JFlashExe requires X server, which is not going to work for most automation pipelines - am I missing something? Project file and flash script attached

  • Hi,

    J-Flash is a GUI application and while it can be controlled / automated via command line, it is not designed for purely headless systems.
    May change in the future but is a bigger change for sure. Currently I cannot share any timeline regarding this.

    This being the first request like this, for J-Flash, I disagree that it is a "very basic functionality" you are asking for. Maybe for you but nor for the majority of our users.
    However, it is what it is right now.

    Your options:
    1) Use J-Link Commander (JLinkExe) if applicable (not designed for production purposes but depending on what you are looking for, may fit)
    2) Write your own customized application via the J-Link SDK (shop.segger.com/debug-trace-pr…ftware-add-ons/j-link-sdk)

  • Thanks Alex. I ended up writing a shell script that starts an X client. Works okay, but adds unnecessary dependencies.

    I have used a bunch of emulators in the past and this is the first time I have encountered one that doesn't provide a headless flash tool. Anyway, the problem is solved for now and I have attached the bash script so others can use it. PS it requires installation of a few things on ubuntu:

    1. apt install -y xorg-dev libglu1-mesa libgl1-mesa-dev xvfb libxinerama1 libxcursor1
