TE0782-100 PL eth1 problem

[Brainiac]

Hello!

I have an issue with te0782-100 module

I tryed to launch ethernet which connects through PL in delivery state on TEBT0782, but it does not work

dmesg output is^

Is it ok that on second ethernet kernel found only generic phy, not marvel?

I tryed to lauch PL ethernet, but it does not work too.
Only when I program PL side with bitstream, when linux is launched on ARM I have ONLY RX packets on eth1

How to solve this problem? Are any tools for mdio interface to check state of phy?

Hi,

we have an 2017.1 reference design available, with both eth:

Currently only with short description on the download webpage. petalinux template project and also prebuilt files are included. For petalinux see also:

I have a feeling that eth1 works only for 10Mbit/s. In 100mbit/s and 1000mbit/s I could not get data transmitting or receving. Connection had only link up and that's all. I could ping device by eth1 in point to point connection, but could not get ping for 100mbit/s and higher
Is it true or I did something wrong?

[JH]

Hi,

did you try out the reference design?

I think yes. I try another time

Is it true that reference design from trenz works with 100mbit/s and higher?

[JH]

Hi,

which version did you try out?

ETH console log from 2017.1 reference design is on the attachment.

Thank you for help!
There were some errors and misunderstanding of zynq work in my mind

I repeat this result and all works with trenz bit and petalinux
