  • [SOLVED] QTPainter error while using JFlash command line interface

    Hi, I have been trying to use the JFlash command line interface to read some data from my device's flash. Everytime I launch JFLASH I get the following error:

    QPainter::setFont: Painter not active

    Is this error safe to ignore? How would go I about fixing the issue so I don't get this error, it causes some of our scripting tools to error out thinking that it's a real error. Is this fix coming in a newer release?

  • Where do you see an error there?
    I do not see any “error” introducer to that message, so it is more an info message.
    If such an output on stdout breaks your scripts, your scripts are broken by design.
    There is no guarantee that J-Flash stays 100% silent on stdout.


    You should also not parse any stdout for errors.
    The return / exit value of J-Flash is what matters.

  • As indicated before, this message is not an error but more some kind of “debug output” from Qt.
    Will be “fixed” in a future version but without priority right now, as it is not an error or real bug / regression.
