Logicore CPRI v 3.x - Why do I see a status code 'F' and then after TX Strobe is applied I see status code 'B'?

Description

Logicore CPRI v 3.x - Why do I see a status code 'F' and then after TX Strobe is applied I see status code 'B'?

Solution

When the core enters L1 synchronization the preferred Ethernet and HDLC rates are not reloaded by the picoblaze. This can cause the link to come up in the passive "B" state after the TX strobe is asserted. This issue will be resolved in the next version of the IP.

For Release Notes and Known Issues for 12.2 for the LogiCORE CPRI v3.2, please see (Xilinx Answer 36969).
