Its quick to download, under 10 minutes, on any reasonable fixed-line connection.
It is using a pretty small rootfs of 400mb so it ends up as a ~13mb artifact. With a connection traffic controlled at 15kbps, the ~13mb artifact communicates to the server that it is in the download phase for the expected amount of time ~2 hours but then the process stalls at reboot until im forced to pull power from the device. Then a rollback occurs on status report.
When i connect the serial connection it seems that the device is stuck at the bootloader phase but this behaviour isnt seen when the connection is unrestricted. Why this would occur at a lower connection speed is to be understood.
With one cpu the same sequence occurs.
