Use of static external xlinks between boards

Postby jzw » Tue Mar 24, 2020 6:54 pm

I have a well proven board based on the XU216-512-FB236 part. This has links five and six brought out to a connector and I would like to communicate with another similar board over both of these links. I have code based on the AN01024 application note that establishes credit between two boards, which I can prove by disconnecting, running code on both, and reconnecting the link.

I can use either link individually by conditioning each in turn but cannot get both to work at the same time.

This may well be a problem with routing through the switches as I do not understand the routing mechanism.
