Thanks to your initial advice I also got the remaining issues solved. It turned out the PCB designer forgot to connect the PHY oscillator with the supply plane. No clock, no working PHY :)

The last thing wrong was the default state of the GPIO output connected with the PHY reset line.

Now my custom eval board happly blinks two LEDs and wait for the connector mezzanine to be finished, so that I can connect ETH and Display.

Okay, so then: Good to hear that everything finally works :D

Might I ask what you're doing with the display and if you're using ChibiOS/GFX? </offtopic>

The whole thing will be controlling a tunable laser system. Right know we're evaluating ChibiOS and will obtain a commercial licence if we settle for it.

I did look at ChibiOS/GFX, but maybe I'll roll my own, that's not decided yet.

Among other things I also started developing a web application framework suitable for µCs, I have a working HTTP server delivering files from a SD-Card and generating dynamic content depending on URL and query variables. You can find the repository at https://github.com/datenwolf/picoweb but the repo lacks the code of the ChibiOS based webserver running on a Olimex STM32-E407
