[Cerowrt-devel] new beaglebone

Modestly weird to see 10Mbit ethernet making a comeback, and all these
other non-wifi wireless interfaces, and quad-core A53s.

At least for the sub-1GHz 802.15.4, that’s for range that wifi can’t get,
due to its lower signal loss over distance.

But 10Mbut Ethernet’s weird (to me)

	They also have a Gpbs ethernet port:

Ethernet MAC	2-Port 10/100/1000

I thought al Gbps ethernet is backward compatible to 10 Mbps? At least the systems I looked at with ethtool clsim that much, e.g.:

Settings for eth2:
        Supported ports: [ TP MII FIBRE ]
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Full 
        Supported pause frame use: Symmetric
        Supports auto-negotiation: Yes
        Supported FEC modes: Not reported
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Full 
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: Yes
        Advertised FEC modes: Not reported
        Link partner advertised link modes:  10baseT/Half 10baseT/Full 
                                             100baseT/Half 100baseT/Full 
                                             1000baseT/Full 
        Link partner advertised pause frame use: Symmetric Receive-only
        Link partner advertised auto-negotiation: Yes
        Link partner advertised FEC modes: Not reported
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: external
        Auto-negotiation: on
        MDI-X: Unknown
        Supports Wake-on: pg
        Wake-on: d
        Link detected: yes

And the 10Mb on the block diagram seems to be for 802.3 single-pair ethernet which is probably exotic enough by itelf

/me googles…

802.3cg? 10base-TIS and 10base-TIL are definitely aimed at industry and
automotive.  And look like they’re trying to be alternatives to CAN and
other networks I’m more familiar with (DeviceNet and ControlNet, from
Rockwell Automation)

10base-TIL looks very much like the time-token-bus model that ControlNet
uses.
