Can't get our products to work with 10 mbps ethernet

[jesperevertsson]

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.

Hi Jesper:

I think you can check the following threads about 10Mbps issue, you need to change code

Re: how to change network interface speed from 100mbps to 10mbps in FRDMK64

That isn't really the functionality I'm looking for. I want it to work with both 100 mbps and 10 mbps switches. Right now it only works with 100 mbps.

And also I tried changing that code just to see if that would make it work with 10 mbps, but it didn't
