The [[Talos II]] and [[Blackbird]] uses the [[AST2500]] for it's [[BMC|Base Management Controller]], which handles power on and power off requests and other tasks.  The AST2500 boots both computers slowly and is not open source friendly.  Raptor Engineering created the Arctic Tern FPGA as a replacement BMC, which boots both computers nearly instantly.

systemd may try to set up a serial-getty on '''/dev/ttyUSB0''' device for you, which may cause some issues.  Simply disable it via:

'''sudo systemctl stop serial-getty@USB0.service'''

'''sudo systemctl stop serial-getty@USB0.service'''

'''sudo systemctl disable serial-getty@USB0.service'''

'''sudo systemctl disable serial-getty@USB0.service'''

+

Also stop and disable any systemd's serial getty services.  You can search for these services via:

+

'''systemctl status "serial-getty@*.service"'''

+

Then disable them via

+

'''sudo systemctl stop serial-getty@SERVICENAME.service'''

+

'''sudo systemctl disable serial-getty@SERVICE.service'''

+

You may need to stop these services at every boot.  For some reason, systemd may not properly disable these services.
