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

Graham, Thanks so much! That should be enough to get me started. I wanted to avoid parts on the bottom of the board as it makes assembly more difficult. Board size isn't too much of a problem. The extra EEPROM programming step is a bit of pain but not impossible. Thanks again! On Monday,

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

Steven: The primary reason for parts on both sides of the boards is just space constraint. With an extra half square inch of space, everything could be on one side. I do like to keep the transient suppressor as close to the RJ-45 connector as possible. You would still need a four layer board to do

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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?

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

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

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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

It's been awhile since I have fired up my Pocket Beagle but I am looking at using it for a project that requires ethernet. Did we ever get to the bottom of the MAC address getting set properly at bootup on either the ENC or the WIZ ethernet chips? On Thursday, October 19, 2017 at 10:11:52 AM

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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 this: https://elixir.free-electrons.com/linux/latest/source/drivers/net/ethernet/microchip/enc28j60.c#L1590 Mark On Thu, Oct 19, 2017 at 8:11 AM

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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 adapter is detected in the kernel. Aside, u-boot configures the on-board MII because the code was difficult to cut out. > On Oct 19, 2017, at

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

The ETH-WIZ locked up overnight running at 48 MHz SPI-Clock. I moved it down to 24 MHz and rebooted. I'll let it run for the rest of the week. --- Graham == > > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google

I have never seen it fail, but since the USB power goes off when my computer goes into deep sleep, it has never been run for more than a few hours at a time. It is at home. I'll set it up on a permanent power supply and run it continuously for a few days, and report back I think you also

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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

Re: [beagleboard] Re: ENC28J60 Click on PocketBeagle

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. --- Graham == On Sat, Oct 7, 2017 at 6:02 PM, Robert Nelson
