IP connection to Kiwi through Kiwi's USB interface

SOLVED

I carefully read the "Using a USB network connection for initial Beagle access" section of the user manual but could access the Kiwi from a Win10 PC or from a Raspberry Pi

On the Kiwi, 'ifconfig'… (more) command lists usb0 with IP address 192.168.7.2 and MAC 40:bd:32:e5:40:02, and usb1 with IP 192.168.6.2 and MAC 1c:ba:8c:a2:ed:73

On the PC, when I plug in the USB cable from the Kiwi, a new DHCP network interface appears but that interface gets no IP address. The beaglebone documentation describes a drive which should appear as well, but Win 10 shows only this additional network interface with MAC 40:bd:32:e5:40:01. That MAC differs by 1 from the usb0 MAC on the Kiwi, so the PC and Kiwi are communicating.

On the Pi, when I plug in the USB cable from the Kiwi two new interfaces appear: eth2 with the same MAC 40:bd:32:e5:40:01 which is assigned to the PC interface, and eth1 with MAC 1c:ba:8c:a2:ed:72, but those Pi interfaces give themselves self-assigned IP address. Running 'tcpdump -i eth1' on the Pi I can see it sending out DHCP request packets but getting no response, so I infer that the BeagleBone is not responding to DHCP on those usb0/1 ports.

However, by configuring the Pi's eth1 and eth2 with static addresses I was able to gain complete ssh and GUI access to the Kiwi at both 192.168.6.2 and 192.168.7.2.

To manually configure those IP address on a Pi, add these four lines to /etc/dhcpcd.conf

pi@Berk-Pi4b-90:~ $ tail -4 /etc/dhcpcd.conf
interface eth1
static ip_address=192.168.6.1/30
interface eth2
static ip_address=192.168.7.1/30
pi@Berk-Pi4b-90:~ $

I don't have a second Kiwi here to test a two Kiwi system, but it seems I could modify the usb0 address 192.168.7.2 in /etc/network/interfaces to 192.168.8.2 and configure the Pi to add a corresponding ethX with 192.168.8.1 (less)

I could imagine installing WD on a BBAI machine and dedicate a core to run it.
But synchronizing Kiwi and WD code upgrades would be a mess.
For example, just this week I was able to upgrade 20+ WD… (more)

For over a year, at KPH I have fed 7 Kiwis from one GPS antenna on the roof: GPS Puck ====> 30M RG-6u =====> $15 passive splitter =====> 7 Kiwis
The 8-way I used is no longer offered, but I… (more)
