The transceiver gxb_locked signal does not assert in the Serial RapidIO 1.25 Gbps version of the Serial RapidIO to TI 6488 DSP Reference Design due to an error in the verilog code.
The following code change is required on line 90 of file srio_1250_x1_top.v.
.gxbpll_locked_rapidio (gxbpll_locked_int), --old code
.gxbpll_locked_rapidio (gxbpll_locked), --new code
This issue will be fixed in a future version of the Quartus® II Software.
The reference design may be downloaded from the following location.
