We have a system where a kasli SoC v1.1 (master) connects directly to 3 kasli v2.0.2 (satellites) with the latest artiq release 8 (software and gateware). I'm trying to use the artiq_coreanalyzer but I get an error.
If I run the example:
from artiq.experiment import *
class BlinkToUnderflow(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("led0")
@kernel
def run(self):
self.core.reset()
for i in range(1000):
self.led0.pulse(.2*us)
delay(.2*us)
And then use artiq_coreanalyzer -p I see the events correctly:
Log channel: 57
DDS one-hot: True
OutputMessage(channel=55, timestamp=69934492602816, rtio_counter=69934492478480, address=0, data=1)
OutputMessage(channel=55, timestamp=69934492603016, rtio_counter=69934492479280, address=0, data=0)
............
OutputMessage(channel=55, timestamp=69934492639016, rtio_counter=69934492639072, address=0, data=0)
ExceptionMessage(channel=55, rtio_counter=69934492639080, exception_type=<ExceptionType.o_underflow: 20>)
StoppedMessage(rtio_counter=69937551992720)

StoppedMessage(rtio_counter=69937564402064)
StoppedMessage(rtio_counter=69937570096024)
If I re-execute the experiment and run artiq_coreanalyzer -w waveforms.vcd instead (the same happens if I use the waveform viewer from the dashboard) I get the following error:
WARNING:artiq.coredevice.comm_analyzer:unable to determine DDS sysclk

How can this issue be solved?
