Implement CPRI by the SFP+ connector on KC-705

Hi All,

I followed the document (PG053) and generated a CPRI of 6.25 Gbps by core generator.

 

It works if connected by SMA as the document illustrate.

 

However, when I tried change the GTP from SMA connectors to SFP+ connectors by changing the ucf file as the following:

 

original: INST "cpri_block_i/gt_and_clocks_i/gtwizard_i/gt0_gtwizard_i/gtxe2_i" LOC = "GTXE2_CHANNEL_X0Y8";

 

modified: INST "cpri_block_i/gt_and_clocks_i/gtwizard_i/gt0_gtwizard_i/gtxe2_i" LOC = "GTXE2_CHANNEL_X0Y10";

 

The generated bit stream is not work and the indicator shows the clock seems some problems. (plz refer to the attachment) I checked and verified the connection of the X0Y10 instance, it shares the same clock with X0Y8 in another example.

 

Is there something I did not notice? 

 

Thanks in advance 

Best Regards 

Amistad

Re: Implement CPRI by the SFP+ connector on KC-705

Please check jumper J4.

By default SFP is disabled on KC705.
