Other Parts Discussed in Thread: AFE7950
Tool/software:
sorry by mistake i put the part number as "AFE7950 EVM" in thread title, But i am trying it on AFE7900EVM, it is the correct part number.
here i am trying the 1GHZ bandwidth latte script on ZCU102 FPGA board, while running that i got the below errors.
and here is the code i am running. And in some forums i saw that this " Los indicator for lane0" this kind of errors will because the LMFS settings that will differ on both LATTE AND FPGA side, but i am quite newbie in this domain, so i am not sure where exactly i need to check that LMFS settings in the TI_204c_IP or else in the GTH transceiver IP .I am attaching the code below. And please do suggest me to resolve the latte errors.
