I want to pass some data from my verilog to my microblaze core in ISE 14.7. I was doing some research and it seemed like the FSL was the easiest way to go about this.
What I did was create a peripheral with one 32b input and one 32b output of the FSL variety. I then clicked configure coprocessor and added my new fsl_link
to it.
That done, it added fsl_link_0_to_microblaze_0
, microblaze_0_to_fsl_link_0
, and fsl_link_0
to my Bus Interface window.
I then did a DRC check and I get
ERROR:EDK:3900 - issued from TCL procedure "::hw_fsl_v20_v2_11_f::check_syslevel_settings" line 14
fsl_link_0_to_microblaze_0 (fsl_v20) - FSL_Clk is unconnected.
ERROR:EDK:3900 - issued from TCL procedure "::hw_fsl_v20_v2_11_f::check_syslevel_settings" line 14
microblaze_0_to_fsl_link_0 (fsl_v20) - FSL_Clk is unconnected.
All I want to do is pass some register values from my verilog to my uBlaze (doesn't even need to go the other direction for now). What am I doing wrong? I am not sure how I need to set up the clocks by my FPGA runs at 200MHz and my uBlaze is clocking at 100MHz if that helps.
