    Hello,

    we tested the network on the PicoCoreMX6X with the B2019.03 Release and it worked.

    Did you update the Kernel-Image, the Rootfilesystem, the Devicetree, and the U-Boot?

    Did you make any changes to the network settings, for example in the file

    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.

    Hello,

    may I ask on which Image-version it worked?

    And does your PicocoreMX6SX-Variant support both Ethernet-PHYs?

    Hello,

    "DriveStrength" is correct for UART.

    Above i talk about the frequency because EMV. As far as i know some customers use drive strenght value to reduce EMV caused by display. Malformed shapes have additional high frequncy overtones.

    I'm also no hardware expert, but to my knowledge the drive strength has influence on the shape of the edges, rather independent from the frequency, at least as long as the signal reaches a stable high or low level. Our hardware department just asked me…

    Hi,

    can you also test the network in UBoot. Does this work?
