The newly created question will be automatically linked to this question. One problem we have is that while the driver works and we have network connectivity under Linux, we randomly get “link down” and “link up” messages in Linux. Keldy Ethernet driver is generic and doesn’t depend on PHY.


Micrel KSZ causing repeated link up / link dow – Community Forums

If the phy has no errata, then generic phy driver in the linux should work fine.

Apr 20, 1: What was the final problem analysis and solution on this issue? Other less possible reason of your problem could be PHY clocks, small but outside of tolerance deviation from required frquency could result in occasion link loss. We have verified the assymetric pause is not enabled in the micrel driver. Other times we can go 20 minutes or more without loosing link.

I thought removing the ptp-enet-clock parameter had fixed my problem, but it came back. Apr 24, After seeing your post, we checked the oscillator datasheet once more, the one we have seems to be worse than Si in terms of jitter specs.

We will try alternative oscillators.
