  • enable RS485

    Hello,


    I would like to use the RS485 with serial port C (ttymxc3) on the demo board.

    However, I can not set the flag SER_RS485_ENABLED in the configuration!

    In Buildroot's menuconfig I activated the RS485 with BR2_PACKAGE_RS485CONF = y


    rs485conf.flags = SER_RS485_ENABLED;

    ioctl(fd, TIOCSRS485, &rs485conf); // write config

    ioctl(fd, TIOCGRS485, &rs485conf) ; // read config again

    printf ("\nflags: %x", rs485conf.flags); // output -> flags: 0


    What else is to be done?


    Best regards

  • QT sample project

    Hello,


    the additions to the .pro file are already in the documentation. After restarting QT Creator, the executable was finally in the list of deployment files!


    I use your Fedora 23 Development machine, picocoremx6sx-B2019.03 and QT Creator 4.0.3.

    Do you recommend a newer version of QT Creator?

  • QT sample project

    Sorry, I searched for the document in the wrong tab.


    The example for the desktop works now.


    But there are some issues with the target device.


    - The list of files to be deployed is empty.

    I added to the .pro file:

    linux-* {

    target.path = /root

    INSTALLS += target

    }


    - Is the configuration for the CMake Tool in Figure 13 correct?

    Would not it have to be CMake (for ARM Cross Compile)?


    - The "general message" window shows an error:

    /home/developer/picocoremx6sx-B2019.03/build/buildroot-2018.11-fsimx6sx-B2019.03/output/host/mkspecs/features/qmake_use.prf(6): 'take_first' is not a recognized replace function.

    Project ERROR: Library '' is not defined.

  • QT sample project

    Hello,


    I can not find the mentioned document "Application Development with QT5" in the Linux folder.

    So far I only know the short description about QT in the document "Quick Start with F & S Development Machine"

    Hello F&S-Team,


    could you provide a QT project file for a non-QT C application (settings for compiler, CMake tool, CMake Generator)?


    Thanks

  • Filetransfer with scp

    Hello,


    I want to transfer a file from the VM to the board with scp.


    In the VM-shell I tried this command:

    scp hello.txt root@10.0.0.63:/tmp

    root@10.0.0.63's password:

    Permission denied, please try again.


    I can't log in, why?

  • no network after image update

    Hello,


    the board is connected to a ethernet-switch.

    The SOM is the PicoCoreMX6SX-V3-LIN with two ethernet ports.


    I don't know what the previos (delivery) Image-version was.I have done a reverse update to uImage-fsimx6sx-V2.0 found on the Fedora-VM.


    Now the ping is working in both directions again!


    boot-message:

  • no network after image update

    Hello,


    after updating to Image B2019.3 the network doesn't work.


    The boot-message shows the error:

    Starting network: RTNETLINK answers: File exists

    FAIL


    a ping from/to the board fails.


    What can be the reason?


    Thanks

  • ubi create rootfs fails

    Thanks, it worked!


    I think the command "nand erase.part TargetFS" is missing in the document "i.MX6-SoloX Linux First Steps" under point 3.3.6 Load and Save Root Filesystem.
