Hi,
I am running a simple code to just initialise SUServo and setting some some parameters to channel 0 and reading them. This is my code:

from artiq.experiment import *


class UrukulInit(EnvExperiment):
    def build(self):
        self.setattr_device("core")
        self.setattr_device("suservo0")
        self.setattr_device("suservo0_ch0")
        self.setattr_device("suservo0_ch1")
        self.setattr_device("urukul0_cpld") #needed?
        self.setattr_device("urukul0_dds")
  
        
    @kernel
    def run(self):
        self.core.break_realtime()
        self.core.reset()
        print("core prepared")
        delay(50*ms)

        self.suservo0.init()
        print("suservo0 initialised")

        self.suservo0.set_config(enable=1) #activates servo
        print("suservo0 activated")

        self.suservo0_ch0.set_y(0, 0.9) #manually set amp to 1.0
        print("ch 0 amp set")


#        self.suservo0_ch0.get_y(0)

        print(self.suservo0.get_status())
        print("finished")

I was using the print statements to see which part of the code is not running properly and I can get everything to run until the print(self.suservo0.get_status()) line which doesn't generate any output and just runs indefinitely. The red LEDs are on so it looks like the DDSs' are not getting initialised. I have tried setting ch0 amplitude to 0.9 and reading back the parameters using get_y methods but that doesn't generate any output either.
Running artiq_sinara_tester doesn't work either because nothing happens.
I have checked that the DIP switches are correct, the CLK input is okay, and the EEM connections are correct too. I even tried to plug in the Urukul board to a different Kasli and I ran into the same problem as before.

This is the device_db file:
