Automotive Ethernet PHY bring-up: lessons learned and debug tips

I would like to share my experience bringing up various Automotive Ethernet Gigabit PHYs on an iMX8 platform.


  • PHY configuration CheckList (= What I need to know about my PHY, my schematic before starting the bring-up)
  • SW implementation (= step-by-step SW integration + common pitfalls to avoid, mainly focused on Linux, but I talk also about U-Boot)
  • Debug tips (= SW and HW tips)

This presentation is based on a training I already gave internally in the Valeo Group (with some extra additions). This experience led to some patches that I hope to push at U-boot and Linux level.
