Hi all,
In our design, tlk10232 is used to convert XAUI to KR. Following is the topology:
BCM56334 <-- XAUI --> TLK10232 <------- KR --------> XL710 (Intel nic)
This link is ok most of the time except that: when XL710 performs a reset procedure, the link will becomes down, and will never be up again!
Under this situation, a data path reset (write 0x8 to 0x1e.e register) have to be performed, then the link becomes up again.
Following is our settings (ref to bring up procedure v2):
Our question:
As the autoneg is operating, why the link can not recover after a reset ?
How to auto recover the link after XL710 finish reset procedure?
Thanks.
