MARVELL 88E1512 DRIVER

The device tree in the newer kernels uses the MACB drivers. As Ethernet technology becomes more prevalent in everyday mainstream applications such as IP phones, gaming consoles, PDAs, printers, and traditional home or corporate network connections, the demand for energy efficiency and advanced process technologies increases. We aren’t using petalinux, but the kernel config stuff all looks the same. Link never comes up on eth1, although I can see received packets on the eth1 interface, as if the default PHY configuration is enough to receive packets in some form. Data Center and Cloud.

However, I don’t see an error in my boot log, and in fact it assigns the PHY id correctly to eth0 and eth I’ve verified that both PHYs respond when using the u-boot mdio commands, however, when running the Linux kernel code, it appears to ignore or not see the addresses in the device tree, and it also seems to not identify PHY1 correctly, attaching a “Generic PHY” driver to it.

It’s almost as if the default config of the PHY is enough to pass data to the eth1 interface even though it hasn’t been configured.

Hoping to get a pre-release of the Finally, I saw this thread for Petalinux, which I was not able to locate the patch for, but it seems related. With the Alaska family, Marvell delivers a new class of Gigabit PHYs designed to meet the demands of next-generation green networks. I had seen that, but we run both PHYs a 1. Link 88e1521 comes up on eth1, although I can see received packets on the eth1 interface, as if the default PHY configuration is enough 88e112 receive packets in some form.

Yes, I have tried it, but eth1 still doesn’t work. I have tried that previously and once marvvell to verify. However, I don’t see an error in my boot log, and in fact it assigns the PHY id correctly to eth0 and eth1: Alaska Gigabit Ethernet Designed to meet the demands of next generation green networks.

There was a fix in the emac drivers, but it’s not being used anymore. This has been tested on Zynq Ultrascale with a Daughter card.

I have looked at the following link, and it appears that the issue of supporting two PHYs was solved in FYI, Tool and Software tags: It’s likely that a hardware workaround in the fabric is easier to implement than digging into the Linux core software. Marvell PHYs products can also be combined with Marvell’s switching products for a margell networking solution. Linux Kernel Thanks Panou.

Driver Downloads Download the latest 881e512 drivers for your specific device or application. It’s not being released in the petalinux So I marveol suggest you to try testing the setup in I don’t have the Marvell datasheet handy, but recall seeing that when run a 1.

We verified that before trying it in the kernel. We are running a single Marvell 88e on a custom board, and 88e15112 refuses to work at all. The state machine for this is pretty simple and basically counts the bits as they go out and just inverts the value for one bit period during the desired address bit for example bit 1.

It will doubtless require changes to the linux driver stack to get it working. This file is automatically generated by Marvll.

According to a Xilinx FAE: There was a little communication confusion with Xilinx. Careers at Marvell Marvell offers a collaborative fast-paced environment where innovative ideas can really make a difference.

Copyright c – Intel Corporation. We have detected your current browser version is not the latest one. The software doesn’t seem to do anything with it. I’m looking for some insight that I’m missing, or some other 88s1512 to indicate why the kernel drivers can’t detect PHY1 at address 1 correctly.
