Hi Johi,

the marwell datasheet can be found on www.eeworld.com.cn

Sorry I haven't read your code yet, but the tse_tutorial.c and tse_tutorial.v from using_triple_speed_ethernet work fine on DE115 board.

These codes were written for 1000 speed. I don't know for other speed.

On DE115 the hardware is only for RGMII ( I asked terasic and the schematic shows it).

If you want to only use the 1000 speed the marwell ( and some other chips ) are set in this mode when reset.

The DDR is necessary.

The demo code tse_tutorial is a goog start.

I hope it will be helpfull.

Regards.
