Review dump mode on SpiNNaker-AER interface on RaggedStone2 board #31

Open lplana opened 7 years ago

Although the Verilog code has provisions to exit DUMP mode, a quick test with a SpiNN-3 board suggests that the interface does not come out of DUMP mode when the SpiNNaker board starts accepting packets.

Also related to DUMP mode, we may want to extend its meaning. Currently DUMP mode indicates that SpiNNaker is not accepting packets, i.e., it's not completing handshakes on the link. It seems sensible to indicate DUMP mode also when the interface is dumping packets because no START command has been received from the SpiNNaker board.

Further tests contradict this initial test. The interface does come out of dump mode.

The issue not closed to keep the semantic discussion open: should the DUMP mode indicator be on when the interface itself is dumping events because it has not received a START command?

@lplana If you are still interested please reopen.
