Today I upgraded my ARTIQ gateware from version 5 to version 8. (It has been a long time coming!) I am able to access hardware connected to the master after upgrading, but not hardware connected to the satellite.
I have flashed the 8.8881 gateware onto the master and the 8.8864 gateware onto the satellite. I performed the flashes via
artiq_flash -d berkeley3master
when plugged into the master and
artiq_flash -d berkeley3satellite
when plugged into the satellite. I then regenerated my device_db.py file via
artiq_ddb_template -s 1 satellite.json -o device_db.py master.json
After doing this I run artiq_master and artiq_dashboard. Once doing this I am able to successfully connect to hardware on the master (i.e. change TTL levels, etc.), but am unable to do so on the satellite. When I run artiq_coremgmt log I get the following:

alpha@control-system:~/control$
As far as I can tell no attempt is being made to connect to DEST#1, which is the satellite.
Looking at the satellite serial output I get the following:
alpha@control-system:~/control$ stty 115200 < /dev/ttyUSB2
alpha@control-system:~/control$ cat /dev/ttyUSB2

No errors are being printed out. Did I make a mistake in configuring the satellite?
Also note that prior to flashing ARTIQ 8 I was able to access the satellite hardware without any issues.
