Hi, we are using the ARM MK60FK512 processor on a custom built hardware with MQX 4.2.0. We have a problem that the rtcs doesn't work when we connect our product to a switch that has 10 mbps speed. I've tried to track the issue in the MQX files and I can see that in the phy_dp83xxx_get_speed() function it correctly returns 10 when connected to a slower switch and 100 when we use a faster switch. This tells me that the phy is working correctly, but I don't know what the problem is. The rtcs functions doesn't return any error codes either.
