Hi, i am using power pc and i have akward problem:
when i choose FM1@DTSEC2 from u-boot as active, i am pinging with no problem, prints using FM1@DTSEC2 and says alive.
when i set "setenv acteth FM1@DTSEC1" i connect both ethernet cable second ethernet become alive. i am observing with leds blinking and data transfer ok with 2.1 Mib/s speed. and prints as using FM1@DTSEC1.
but when i remove other cable prints using FM1@DTSEC2 and fails.
there is no connection between two PHY ICs and only difference is there is ethernet switch on FM1@DTSEC1 line.
PHY ic is KSZ9031.
what can be problem? is there anyway force to use FM1@DTSEC1.
