Hello,

I am trying to run a simple example experiment on an urukul where I output a single frequency. I am using gateware (6.7659.c6a7b8a8) and software (6.7670.1b3fa342).

The script I would like to run is below:
`from artiq.experiment import*

class Urukul_Frequency_Pulse(EnvExperiment):
def build(self):

    self.setattr_device("core")                            
    self.setattr_device("urukul0_dds")  # this is the name given to the AD9910 device in my device_db.py rather than urukul0_ch0 for instance... not sure why that is

@kernel
def run(self):  
    self.core.reset()                                    
    self.urukul0_dds.cpld.init()
    self.urukul0_dds.init()
    delay(10 * ms)
    
    freq = 100*MHz
    amp = 1.0
    attenuation= 1.0

    self.urukul0_dds.set_att(attenuation)
    self.urukul0_dds.sw.on()

    self.urukul0_dds.set(freq, amplitude = amp)
    delay(2*s)                                              
    self.urukul0_dds.sw.off()      `

There are two clear problems I'm running into: first there is no sw_device assigned to my AD9910 in my device_db.py so I cannot call the method self.urukul0_dds.sw.on(). When I try this I get the error

<synthesized>:1:1-1:60: error: host object does not have an attribute 'sw' <artiq.coredevice.ad9910.AD9910 object at 0x7f9267116e50>
Looking in my device_db.py I see:

device_db["urukul0_dds"] = { "type": "local", "module": "artiq.coredevice.ad9910", "class": "AD9910", "arguments": { "pll_n": 32, "chip_select": 3, "cpld_device": "urukul0_cpld" } }

There is no sw_device like "ttl_urukul0_sw0". Is this something I can add myself? How do I turn on output from the urukul without this switch device? The second issue comes at initialization of the ad9910 and cpld. If I simply run

`class Urukul_Frequency_Pulse(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("urukul0_dds")

@kernel
def run(self):  
    self.core.reset()                                       #resets core device
    self.urukul0_dds.cpld.init()                            #initialises CPLD on channel 1
    self.urukul0_dds.init()   `

I get

Is this because of the software gateware mismatch? Any support would be greatly appreciated!
