HI,


Unfortunately there is that case here. PMA adaptation process flow is not automatic.

Alright, I was able to make this work by writing a state machine that implements the operations listed in section 8.2.13 on page 211 of the E-tile PHY user guide. Unfortunately, I don't know what to wait for before starting the sequence, right now I just wait 65k clock cycles. Not a particularly clean solution, but I suppose it will be sufficient at least for the time being. The documentation for this stuff is really quite terrible.
