What will happen if I specify "core_addr" : "10.0.0.51" in the system description file of a satellite Kasli SoC?

Can satellites be pinged via ethernet and controlled via artiq_coremgmt separately from the master and the other satellites?

(This must be possible, because how would I otherwise configure the master and all satellites with artiq_coremgmt config write -s rtio_clock ext0_bypass_125 if I want to lower phase noise after I have set up Sinara and Artiq fully?)

    Can satellites be pinged via ethernet and controlled via artiq_coremgmt separately from the master and the other satellites?

    No. See here.

    (This must be possible, because how would I otherwise configure the master and all satellites with artiq_coremgmt config write -s rtio_clock ext0_bypass_125 if I want to lower phase noise after I have set up Sinara and Artiq fully?)

    The satellite is bound to the master clock in any case. Networking and clocking configuration are by and large meaningless in satellites, if set they're ignored by the firmware.

        architeuthis Regarding the clock on satellite Kasli SoCs, could I please ask you some more specific questions?

        Abstractly: Do the satellite Kasli SoCs generate any kind of clock signal at all? Or are their internal frequency references (various crystals) completely bypassed by the clock signal from the master Kasli SoC?

        In practice:

        1. If I set artiq_coremgmt --device 192.168.1.30 config write --string rtio_clock int_125 on the master, will the satellites also have 125 MHz clock frequency immediately after this command?
        2. And will it be one of their own crystals generating the signal or will it be the master's crystal?
        3. If I then set artiq_coremgmt --device 192.168.1.30 config write --string rtio_clock int_100 on the master, will the satellites also have 100 MHz clock frequency immediately after this command?
        4. And will it be one of their own crystals generating the signal or will it be the master's crystal?
        5. If I then set artiq_coremgmt --device 192.168.1.30 config write --string rtio_clock ext0_synth0_10to125 on the master, will the satellites also have 125 MHz clock frequency locked to the external 10 MHz reference immediately after this command?
        6. And will it be one of their own crystals generating the signal or will it be the master's crystal?

          artiq_coremgmt makes no immediate changes. A restart is required for most config settings to take effect. Rather than asking what individual commands will do, why don't you try them and see?
