AFE7900EVM: AFE7900 RX Link Up Failure Despite XCVR and Lane Locks

Part Number: AFE7900EVM
Other Parts Discussed in Thread: AFE7900

I am running the AFE7900 1T/1R design using the FPGA design and Latte scripts provided by TI. The LMK and AFE configuration scripts run successfully, and I am getting XCVR lock, all JESD lane locks, and valid output data.

However, during AFE configuration, I observe the following errors:

  • Fixed ones error on all lanes

  • "Couldn't get the link up for device RX: 0; Alarms: 0xf0000000"

I have attached the LMK and AFE configuration scripts along with the error screenshot. Could you please help identify the possible cause of these errors and whether any additional checks are recommended?
