 Graham,
 If you don't mind could you answer a few questions?
 You have parts on both sides of the board.  Is this primarily because
 of the size constraint or to keep traces short as possible?
 Is it possible for the driver software to load the MAC address of the
 Beagle Bone into the LAN9500A?  It does not appear that the preprogrammed
 MAC address EEPROMs from Microchip work with these USB-to-Ethernet chips.

 You would still need a four layer board to do the power distribution
 cleanly.

 In this design, the MAC address can not be assigned by the Linux driver.
 It takes a Windows app, from the Microchip website, that needs to
 access the LAN9500A
 chip from both sides to program it. That is, it needs to access both
 the USB-2 connection to the
 LAN9500A, and have the Ethernet connection from the LAN9500A on the
 same
 sub-net as the PC running the programming app. Even though the MAC
 address is
 held in an EEPROM, I don't think there would be any way for the user to
 change it
 without reproducing the programming connections.

 I am not aware that Microchip sells preprogrammed EEPROMS with the MAC
 addresses,
 normally you get blank EEPROMS and you supply and program the MAC
 address.
 Although for extra money, you can get either Microchip or some of the
 distributors to program
 memory parts.

 I have heard that Microchip will sell a small number of MAC addresses
 as a courtesy,
 but I have not done that. The normal process is to buy a block of MAC
 assignments
 from the IEEE which is the global coordinator.  If you buy a large
 enough block, you get

2019-08-05 Thread Graham
The programming of the MAC address in the EEPROM is not an issue, once you
are set up for it.
There are some other Ethernet connection options that you can turn on/off
at the same time.
But the program remembers what you want, and even auto-increments the MAC
address for you if you are programming in sequence within a block
assignment.
The program also does a functional exercise of all kinds of Ethernet
options, anything you have enabled, so it also constitutes a reasonable
final test for Ethernet.
Only takes 20 seconds or so.
I think you will need to pin out the USB-2 (port 1) lines, so that you can
get at them with a USB cable from the programming PC.
If the PocketBeagle plugs into your carrier board, you could build a dummy
USB connection board that temporarily replaced the PocketBeagle for
Ethernet programming.

assemble on 2 sides is no issue
populate one side, reflow solder, populate the other side, reflow solder
the surface tension will keep the parts on the other side IF the solder

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

2019-08-03 Thread graham
I have a working design for an Ethernet Cape for a Pocketbeagle.
It is basically the reference design for a Microchip LAN9500A implemented 
as a four layer PCB cape for the Pocketbeagle.
It talks USB-2 to the PocketBeagle, and 10/100 Ethernet to the outside 
world.
The driver is already in the Beagle software distributions, so the Beagle 
grabs it as part of the normal boot process, and it shows up as eth0.
It has the optional EEPROM that can be programmed to permanently hold a MAC 
address assignment.
I don't plan to do anything with it, so if someone wants to use it, you are 
welcome to it, but you will need to build and program them yourself.

Okay.  Are there any other options for adding Ethernet on a carrier board 
short of using the Octavo chip directly?

Sorry to dredge up an 18-month-old topic but I was wondering if any of the 
new images addressed the MAC address issue with the ENC28J60?  I am 
revisiting the PocketBeagle for an application that needs wired Ethernet 
and USB Cellular Modem.  Is there a better approach for ethernet than the 
ENC28J60?  I need a board-level solution, I am making my own carrier board.

Thanks.

2018-09-19 Thread reynoldskyle66
Robert,

Thank you for your response. We are hoping to use two wiznet devices on the 
pocket beagle. 

The use case is difficult to describe, but the project requires that we 
have two Ethernet ports. 

I was able to utilize both SPI buses with the wiznet. I won't have a second 
wiznet to test using two on one pocket beagle until tomorrow. 

When I get my test results I'll be sure to update this form. 

-Kyle

Hi Robert, 

Steve Kronk and I are working on the same project. I was able to help him 
to get the wiz-click to work on SPI0, but I'm still having an issue getting 
the SPI1 to work.

When I use PB-SPI0-ETH-WIZ-CLICK.dtbo in the uEnv.txt it works fine, but 
I've tried using PB-SPI1-ETH-WIZ-CLICK.dtbo on every address in the 
uEnv.txt with no success.

The objective of our project is to utilize two separate Ethernet ports to 
transfer files with a pocket beagle

While using SPI1, the wiznet powers up and the LEDs light up, but the 
ethernet port is not set up. 

I'm using the most recent kernel and cape overlay. Any assistance would be 
greatly appreciated.

here is my version.sh

Correct it's still and issue.

Used to be you could set mac address via env ethaddr in uboot. Does this
still work or via device tree? Seems like the kernel driver would support

So can we configure the MAC on the ENC? The MAC address is fetched using 
am335x_evm.sh in /opt/scripts. Seems like it could be modified for if an

Correct, neither the ENC28 nor the WIZNET based modules have a
built-in mac address (no eeprom on the module). So it's kinda-random
on every bootup..

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

2017-10-10 Thread Graham
The MAC address on this ETH-WIZ is unstable.

The original MAC address was the same Saturday through Tuesday, through 
many reboots and different image installations.

I updated the kernel tonight, and after rebooting, the ETH-WIZ appeared to 
stop working, but it turns out the MAC address had changed, so the PB was 
assigned a different IP address.

I then did another reboot, and it came up on a third MAC address (and 
another IP address assigned by the router.)

Another few reboots and a few power cycles, and it has not changed again, 
yet.

None of the three MAC addresses had a legitimate OUI.

So there is a random number generator somewhere making up MAC addresses 
(which is a violation of sorts of the MAC address assignment process.)
And so far, I have not figured out what triggers it.

So far, I have seen (as seen in 'ifconfig' and confirmed as being used on 
the network by the router)
*86:37:73:45:44:E9  *
*62:C0:73:03:5E:AD*
*FE:7F:41:5A:31:F9*

This is weird. None of the three are in legitimate block assignments.

I wonder if there is away to measure the processor overhead between the ENC28 
and the WIZ chip.  Network thruput is not drastically different but curios 
which is most efficent use of processor.

The ENC28 has Max SPI clock of 20Mhz so if I understand Graham's explanation we 
could go up to 16Mhz on spi.

Yeah what Graham said. I seem to recall that the SPI bus could potentially
handle faster speeds too. But I've also read that above ~48Mhz the bus can
get noisy.

The possible bus frequencies are integer divisors of 48 MHz, so only option
above 24 MHz is 48 MHz.
Spec on the W5500 chip says it will run up to 80 MHz.
So, I will recompile the ".dtbo' for 48 and report.

Thanks for pointing out speedtest-cli.

I followed your tutorial and got my ETH-WIZ 10/100 Mbps Click running,
since Robert released the overlay for that yesterday.

The one addition to your tutorial is that it also required upgrading the
kernel to 4.9 as part of the install, per Robert's instructions for the
ETH-WIZ.

As you say, it boots, and just works.

Running speedtest-cli ...
I get 3.3 Mbps down, and 4.6 Mbps up.

Confirmed that the chip had negotiated a 100 Mbps connection, so not the
connection.

I note that, in reading the source for the '.dtbo', that the SPI clock is
set to 12 MHZ.
Recompiled the '.dtbo' with SPI clock at 24 MHz.


How fast can you push the spi bus? I've just used the 12 mhz, as it was the
default for one of the device tree in the docs..
