12 years ago --- Quote Start --- It seems OCT causes this problem. When I change the OUTPUT_TERMINATION setting of these pins from "SERIES 50 OHM WITH CALIBRATION" to "SERIES 50 OHM WITHOUT CALIBRATION", everything is OK. mem_clk/mem_clk_n appear and test_complete will be asserted. There are 50ohm calibration resistors connecting to RUP and RDN pin on my custom board. I just don't know why. Could somebody explain it? --- Quote End --- I am facing the same problem ,i am try to solve it,but i wonder where to change the OUTPUT_TERMINATION,could you show me please ! I wonder how was your work going ,is it work later ?:) waiting for your reply! thank you !
