No output from asg command #513

I am working with a Debian 11 system and have installed pyrpl (0.9.6.0)from GitHub master in a conda environment (python 3.9). The setup can recognize the Redpitya board (running with their 2.0 OS) and I can also see the inputs to the board through pyrpl's 'scope' module. However, the 'asg' module does not work; it doesn't give any output when requested. Below is the sequence of steps I am running for this.

After the above set of commands, I do not see any output from the 'out1' port of the Red Pitay board. Not sure if the warnings I see above about some of the attributes is indicating something. FYI, if I use the Red Pitya web app, I can generate output from the 'out1' port, so I don't think it is a hardware problem. Please let me know if there is a way to debug this issue. Thanks.

Not sure what is happening but the warning message suggests that the lockbox module is trying to set up some modules. So you might have a conflict between two modules outputting signal on out1. I suggest you use the scope to debug. You can visualize the signal from asg0 and out1 separately and see if they match. Good luck !
