AFE7769EVM: Issues with AFE7769EVM bring up?

Part Number: AFE7769EVM

Hello Team,

I have a customer having trouble bringing up the AFE7769EVM. Can you please take a look at the following and provide your feedback.

I installed AFE7769EVM and TSW14J56 software and GUI, applied 10MHz clock (0dBm signal level, please let me know what the signal level should be) to LMK CLK IN (also, please let me know if 10MHz should be applied to LMK CLK IN) and followed the steps in section 4 of “AFE77xxEVM User's Guide” document.

 

Up to section 4.4, everything looks good. However, after running basicBringup.py the following errors and warnings were reported. I ran the basicBringup.py for the second time as mentioned in the document and got same errors and warnings. The log files for both tries are attached.

 

Could you please review the log files and let me know why these errors and warnings are reported?

 

Please note that after running the basicBringup.py the AFE7769EVM board draws around 2.6A that is close to what is mentioned in the 4.4 section.

    Hi, 

    • 10MHz reference clock is not a mandatory to bringup AFE77xx. 
      It is only required for external phase clocking. Normally, 5dBm power is used. But, I observed 0dBm also worked fine. 
    The errors reported above are normally reported when AFE is boot-up w/o before FPGA is setup and send the signal. Instead of running bring-up script again, please try below script. Below sequence is TX ReSync procedure. if FPGA-side setting is proper, the errors should be gone.
