Hi

problem "Ethernet programming does not send out the UDP packets on correct interface"

After suffering from this problem too I found the problem solution.

But I did not understand how to implement  it. What do I do with the eflash directory files or with the eflash.exe app file?

TIA

    Hi,

      Yes, the solution is to disable other network interface cards other than the one that is on the same LAN as the MCU client. The eflash has the same issue as it lacks the option to select which local interface to use. Currently, LMFlash/eflash may send the magic packet over an interface different to the one it was told to use as it uses whichever adapter enumerates first in a call to the Winsock function gethostbyname(). Although we have no update for the utility, you are free to modify and rebuild it.
