just starting out, and I'm wondering if this is a setup problem on my end.  any idea how to fix this error?
```
% glasgow run uart -V 5.0 -b 1200 tty
I: g.device.hardware: device already has bitstream ID 8d6d8b1c0b4fbb03a3e4674f55b2cb66
I: g.cli: running handler for applet 'uart'
E: g.cli: register 0x00 does not exist
```
