O.K. so that suggests the issue is on the Armada side. > How would you suggest to investigate this issue? I presume reboot works O.K? So it is possible to toggle the reset multiple times, but reboot must do something additional which makes it work? Do you have sources for the bootloader? Are there status bits in the comphy about the state of the link? Maybe comphy needs to be kicked to reestablish the link?
