Hello,
after our satellite arrived i tried to setup it up and followed all steps provided by the manual.
I also had to flash the master and satellite which worked perfectly fine (no errors where thrown and in logs the right soft- and gateware version are shown).
After all of that i tried to test the setup with artiq_sinara_tester. The master "hardware" worked perfectly fine
but as the urukul DDS on our satellite should be tested it began to stuck and didnt react anymore:
*** Testing Urukul DDSes.
urukul0_cpld: initializing CPLD...
urukul0_cpld: testing attenuator digital control...
urukul0_cpld: done
urukul1_cpld: initializing CPLD...

After that I powercycled both the master and satellite to get the serial output .
1) Master boots without satellite on power:

3) after that i tried to set a frequency to urukul1_ch0 via the Dashboards Moninj widgets. Nothing happens and in
the coremgmt log only
INFO(runtime::mgmt): received connection
appears

Right know I am at the end of my knowledge how to troubleshoot this problem by myself.
The master and satellite are connected via an optical link which was delivered with the satellite and are connected
how it was proposed in our bitstream readme.
Special in our setup is that we use an externel clock reference of 10MHz connected to the master clock in.
I thank you guys in advance for ur help!

Make sure master gateware, satellite dateware, device db template version, and software version all match and that the device db is generated from the right JSONs.

    While you're double-checking you also might want to check your routing table, though I'm not sure if it was a routing problem if you wouldn't get RTIODestinationUnreachable first --

    [ 2.782439s] INFO(libboard_artiq::drtio_routing): routing table: RoutingTable { 0: 0; 1: 0; }

    reads to me like it's routing both destination 0 and destination 1 to the local RTIO core 0, which is correct for destination 0, but not for destination 1, which being a satellite surely requires at least one downstream hop first.

      rjo i checked artiq_ddb_template --version and compared it to the soft- and gateware versions (at least the satellite shows both as the same in the logs) and all where the same.

      architeuthis yes that was one mistake and i changed it to 1: 1 0 .
      now artiq_sinara_tester stucks at urukul2_cpld: initializing CPLD... .

          10 days later

          Can you post your device_db and the code you're trying to run? Also did you generate your ddb using both the master and the satellite json files? This forum post might help

          Can you try to change eeprom_urukulN to

          device_db["eeprom_urukulN0"] = {
    "type": "local",
    "module": "artiq.coredevice.kasli_i2c",
    "class": "KasliEEPROM",
    "arguments": {"port": "LOC0", "address": 0xAE},
}

          in your device_db.py?
