DDS RF

RF red light is always on even though I am not running any code, I am not sure what the problem is, please help me, my firmware and software are bete version of artiq-6.
So far, I have seen the switch, m-labs says I am suservo, but I don't know if I really am, I have also tried the methods they gave me, but they are not very effective, the following is my current situation and my device_db.py file.

Initialize it.

JJim · Nov 25, 2024

rjo Initialize it? What does that mean? What should I do, please

Ssteine01 · Nov 25, 2024

What @rjo probably means is that you have to initialize the Urukul devices (https://m-labs.hk/artiq/manual/core_drivers_reference.html#artiq.coredevice.urukul.CPLD.init and https://m-labs.hk/artiq/manual/core_drivers_reference.html#artiq.coredevice.ad9910.AD9910.init) after you power-cycle the Kasli. You can do this by executing

self.urukul0_cpld.init()
self.urukul0_dds.init()

and similiar commands for the other DDS units. If this is working, it is also a good idea to add these commands to the startup program on the crate (https://m-labs.hk/artiq/manual/configuring.html#flash-idle-and-or-startup-kernel), so they are executed after power-cycling the system.

steine01 Thank you for your reply. I tried your suggestion but reported the following error to me
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Jim the device is called "urukul0_cpld" and not "urukul_cpld0"
