Hi.
I've connected 2 EVMs using a HyperLink cable, and am attempting to run the example program available in the PDK for a board-to-board connection.
Configurations: 4 lanes x 6.25 Gbaud.
When I set clock rate by using #define hyplnk_EXAMPLE_REFCLK_USE_PLATCFG, the program hangs when it tries to access remote registers. Console IO is below:
[C66xx_0] Version #: 0x01000105; string HYPLNK LLD Revision: 01.00.01.05:Mar 3 2014:19:49:43

However, the "other side" never comes up. How do I fix this?
Thanks.
