Hi,
anybody test the synchronization with reference clock of usrp2? Now with
command

clocks_enable_test_clk(true, 1);

I still get drifting between J503 and reference clock,is there anybody
make it works?

Thanks for any given words!

That line turns on the test clock output, but doesn’t turn on locking.
In order to turn on locking you need to add this as well:

clocks_mimo_config(MC_WE_LOCK_TO_SMA);

Burn the attached image on your SD card and I think you’ll see it lock.
