ZCU216 Board Description

[EeshGupta]

When I try to print out the following:
soc = Pyro4.Proxy(ns.lookup(server_name)) soccfg = QickConfig(soc.get_cfg()) print(soccfg)

The print line produces the following error:

`KeyError Traceback (most recent call last)
in
1 soc = Pyro4.Proxy(ns.lookup(server_name))
2 soccfg = QickConfig(soc.get_cfg())
----> 3 print(soccfg)

KeyError: 'dacs'`

Indeed when I print out the configuration using
soccfg.get_cfg()
I get the the output below which does not contain 'dacs'

I suspect you might be running different versions of the QICK library on the PC and on the QICK - specifically, an old version on the QICK.

Could you double-check the versions? One way (depending on how you installed the library) would be to run import qick; print(qick) to find what directory you're loading the library from, then git log in that directory.

I get this :

[EeshGupta]

looks up to date

[meeg]

Yes, that's up to date - this is the version on the QICK, or on the PC? (I am assuming you are running a Pyro server on the QICK, and trying to connect to that from a PC.)

[EeshGupta]

yes that was the problem. Qick repo was not updated on the board. I had to delete the existing one and then redo the qick installation on the board. The problem is then solved. Thanks
