As far as using the gether gadget driver for USB, I was kind of thinking
the same thing, but I did not comment at that time. e.g. should be a lot
faster than "slow" SPI ethernet. But while on the subject, I'm thinking the
PRU's could be used as well. Either as "software" SPI interface, or perhaps
something else I'm unaware of.

When I tested gether, I tested using iperf, which seems to be "the
standard" for old school linux admins. However, with that said, I usually
prefer real world tests, as that tells me what I can expect when I use an
interface as such. Not some "mumbo jumbo" that may, or may not have
anything to do with what I'm trying to accomplish.

As far as the pocketbeagle goes . . . I do not own one, and do not
currently plan on having one any time soon. But I have tested the "bejesus"
out of the blacks, and the greens. They actually achieve better networking
speeds than most Windows based desktops / laptops. On a PC, under windows,
you'd be doing good to get 10-10.5MB/s through put over a fast ethernet
connection. On GbE, the fastest I can think of personally, was around
60MB/s and that was not constant. Do note, that I used Intel Pro NiC's . .
.but the bottleneck was, I'm thinking in the PCIe lanes of the motherboards
. . .

Re: [beagleboard] Re: Adding a USB Port to PocketBeagle

I am just reporting what "speedtest-cli" says.

I note that watching "htop" at the same time, on the USB-2 to Ethernet
tests, the CPU is maxing out at 100 percent, so the speed is not
necessarily constrained by the network interface, but the CPU's ability to
feed it, through the USB stack.

I don't know how speedtest-cli works. If it runs a random number
continuously, then we might be testing the speed of the random number
generator, rather than the network.  If it builds a large data table in
advance and just streams the table, then it is probably representative of
the fastest the system can run.

A long winded way of agreeing with you.

But, there is no doubt in my mind that the USB-2 to Ethernet interface is
about an order of magnitude faster than the SPI to Ethernet interface.

One conclusion is that putting a 1Gb Ethernet interface on a PocketBeagle
is a waste of money and power.  A 10/100 Mb USB-2 to Ethernet interface
would be cheaper, just as fast for throughput, and about one fourth the
power.

I've real world tested ethernet on several A5A's, several C's, and a
boatload of green's.  Down speeds 11.6MB/s( that's megabyte ), up speed
11.4-11.5MB/s.

Real world test was a NFS share, reading / writing 1GB of data, or more.

Additionally, I've benchmarked USB networking, Down speeds 105 Mbit/s, and
uploads were a bit shy at around 85Mbit/s.

You may want to check to make sure your speed test is accurate.

I hacked a "quick and dirty" second USB port as described.
Then connected a LAN7500 USB-2 to Gb-Ethernet board.
Came right up, drivers are already in the kernel, no device tree changes.
Connected to the network at 1 Gb.

speedtest-cli results (on a 1 Gb up/down network)
Download 27 Mbps, Upload 41 Mbps.

And it has a legitimate MAC address.  :-)

(for comparison, BBB Rev.C is download 60 Mbps, upload 70 Mbps, which
is about all I would expect out of a 100 Mbps connection.)

Re: [beagleboard] Re: Adding a USB Port to PocketBeagle

[Dan Brown]

If you are just trying to hook up a quick and dirty connection, then tie 15 
and 13 together for grounding the ID pin.  Then you will tie 5 and 7 
together so the CPU understands there is a USB port in use and it is 
powered.  Your USB connector connects then to pins 7, 9, 11, and 15.   Pin 
15 is already connected to system ground.

In my circuit I am using the Power section from the BBB to do this a bit 
cleaner.

On the pinouts 5,7,9,11,13 and 15 are shown as USB1.  So:

tie ID to Gnd (15,13) and 15 to gnd on the connector
There is a Vin(7) and Vbus(5).  One of those are not used for the +5

Is  Vin used when the power is flowing into the PB from the USB?

[beagleboard] Re: Adding a USB Port to PocketBeagle

[Dan Brown]

On the expansion connectors, the +5V from the built-in USB port is 
connected to the pins labeled VOUT on the back.  GND labels ground pins.

Issue was solved via help from the IRC channel.  Issue was the Extra pins

I have now created a Expansion board that adds a Host port with proper 
switching of power, and ESD protection.  Details are at:
