Running the experiment:

from time import sleep

from artiq.coredevice.core import Core
from artiq.language import EnvExperiment


class CheckCounter(EnvExperiment):
    def build(self):
        self.core: Core = self.get_device("core")

    def run(self):
        print(f"counter: {self.core.get_rtio_counter_mu()}")
        sleep(1.0)
        print(f"counter: {self.core.get_rtio_counter_mu()}")

On a kasli v2.0 you get something like:

print:counter: 970749070566752
print:counter: 970750149100312

Depending on how long the kasli has been running but on Kasli-SoC you always get:

print:counter: 0
print:counter: 0

I would expect it to print the uptime in ns.

I ran code you provided, but was unable to reproduce the issue. I also added @kernel decorator, but that didn't have any effect. Output values seems to be fine:

counter: 1495496331440
counter: 1496540367824
