Tool/software: Linux

Hi ,

I am using AFE7500 card on K2l EVM .There is an issue with RSFDK 4 lane Jesd  configuration.

On executing the following commands

radio reset

radio select 2x2-4xLTE20-SC-JESD1-HD

radio init

Then dsp binary is loaded and run.

radio on 2540 2660

Following Error is reported:

Suggestions would be helpful.

Thanks,

  • Sandeep,

    As you probably have noticed, we have fairly limited support on K2L now. These are the feedbacks I got from the domain expert on this topic and I hopefully it is useful. I am sorry but I don't have much more to offer.

    "In general, the user must have the proper setup for RFSDK, there are several different setups allowed.
    Recheck the RFSDK2 installation and initial selection of board type.
    4 lane RFSDK configurations also have special requirements for (2) AFE7500s.
    Sometimes a special power cable is needed for the 2nd AFE7500."

    best regards,
