no PHY setup on Zedboard using petalinux 2014.2

I have made a simple Zedboard configuration using Vivado 2014.2 and Petalinux 2014.2 under SUSE enterprise. The configuration just has the switches, buttons and LEDu2019s.
After exporting things from Vivado I run through the following

petalinux-create --type project --template <CPU_TYPE> --name <PROJECT_NAME>
cd <directory which contains hardware description file>
petalinux-config --get-hw-description -p <plnx-proj-root>

I use the menu to select SD card booting then run;

petalinux-build

Finally I do;

petalinux-package --boot --fsbl <FSBL image> --fpga <FPGA bitstream> --uboot

After copying the BOOT.bin and image.ub files onto and SD card the board boots up and runs my little test app ok.

I tried ifconfig 192.168.1.3 and that was OK but I get no response from a ping on the Ethernet. Looking at the boot results is appears I have the following error
u201CConfiguring network interfaces... xemacps e000b000.ps7-ethernet: eth0: no PHY setupu201D

Apparently this means I have no Ethernet driver, so my question is simple, what do I have to change in the build configuration to get this driver built for the Zedboard?

Thanks in advance for your help

This is almost certainly an issue with the devicetree. Tske a look at the bsp package for 2014.2 under the zedboard reference designs for the correct entry.

You are correct the system-top.dts under subsystems/linux/configs needs this adding

&ps7_ethernet_0 {
tphy-handle = <&phy0>;
tmdio {
tt#address-cells = <1>;
tt#size-cells = <0>;
ttphy0: phy@0 {
tttcompatible = "marvell,88e1510";
tttdevice_type = "ethernet-phy";
tttreg = <0>;
tt} ;
t} ;
};

I donu2019t understand why this is not added automatically as the marvell option in selected in the kernel configuration PHY Device support and infrastructure menu so maybe this is a bug.

Thank you for your help the my Ethernet works fine after I manually add the above and rebuild.

I'm running into the same problem on the microZed -- which has a Marvell 88e1512.

I've implemented this in either ps.dtsi and system-top.dts (adjusting the "compatible" line accordingly)

Neither location changes anything.

My kernal has all the MDIO options set...

Always the same:

"Configuring network interfaces... xemacps e000b000.ps7-ethernet: eth0: no PHY setup"

uBoot works fine. (I realize that's different)

I would suggest trying PetaLinux 2014.4, which seems to have corrected some ethernet issues.

That said, this post might be helpful if you need to stay with PetaLinux 2014;2: http://zedboard.org/content/device-tree-fo-zynq-20144-linux-317

(shaking head)

I'll try that in the morning.

What a nightmare this project/product has been.

Nothing seems to work 100%.

The ocean of documentation is filled with bugs.

Every next step is hours of fighting a problem that probably shouldn't exist in the first place.

I'll be back to report my results.

I downloaded but decided to spool up the BSP for 2014.2 for the microZed020 and realized the Ethernet fixes that go in system-top.dts go OUTSIDE the top set of lines.

I wasn't getting a warning/error -- and that was the why the entry wasn't making it to the .dtb file.

So no need to jump to Vivado/Petalinux 2014.4 just yet.

I'm finding version jumping is a precarious thing.

Thanks for letting us know how you resolved the issue.

I would still encourage you to move to PetaLinux 2014.4. In long term testing of Ethernet on the MicroZed we, and several customers, have observed occasional errors using PetaLinux 2014.2 that do not appear in the same testing with PetaLinux 2014.4. We don't have a root cause for the errors but have been able to reproduce the results.

And I will eventually...

I'd like to get my base image working first.

Now that Ethernet is working (not sure the LED's are correct. Only the YEL LED shows up on a 1Gb connection), I need to get I2C-0 working on the PMOD connector (will post separately - it's not working)

Would you happen to have the datasheet (or can provide guidance) on the 88e1512 used on the uZed-020?

Thanks,

-Ben

Here is a forum post on the issue of MicroZed Ethernet LEDs that might be helpful:
http://zedboard.org/content/ethernet-leds-constant-and-not-blinking

As mentioned in that post the Marvell PHY data sheet is under an NDA (Non Disclosure Agreement). You can work with your local Avnet/Silica FAE to request access to the data sheet from Marvell.

(SOLVED)

As a follow-up on the LEDs, I'm guessing they're ok.

It seems:

GRN = 10Mb/s
YEL/GRN = 100Mb/s
YEL = 1Gb/s

For anyone else who'd like to know.
