issue with ethernet interface

[aniqurrehman]

after installing pynq networking i am unable to access pynq via browser.
is this due to changes made by pynq networking to the eth0 file in interfaces.d??
and i also don't have old backup up file.

The setup.py should have made a copy in your system. You can recover using that.

For you issue, there are several things to do first:

1.upgrade your PYNQ image to v2.2:
sudo pip3.6 install --upgrade git+https://github.com/Xilinx/PYNQ.git

2. then pip install the latest networking overlay.

i checked now PYNQ networking was not completely installed.
after changing eth0 file contents as following i was able to access pynq thorough browser.
auto eth0
iface eth0 inet dhcp

auto eth0:1
iface eth0:1 inet static
address 192.168.2.99
netmask 255.255.255.0

i i upgraded the pynq and installed the latest networkking overlay from pynq which changed my eth0 file contests as following but still i am not able to access jupyter-notebook via browser.

[aniqurrehman]

how to resolve this issue because without it i am not able to use this overlay.

I need more information. Can you introduce a little more about your setup? Wireless, wired? Dynamic IP or static IP?

[aniqurrehman]

i am using static ip and using wired setup following is the snapshot of the system.

[yunqu]

Is your snapshot showing the system before installing networking overlay? (if not can you attach the screenshot after installing networking overlay)

If so, it seems that the pynq networking has not been installed successfully. Otherwise you would be able to see br0 as an interface name shown there.

Also, after installing networking overlay, try reboot the board to see if br0 shows up.

I have not tried static IP with the networking overlay; however it should work as long as eth0:1 shows up correctly.

[aniqurrehman]

no it is after installing the networking overlay actually i removed br0 line from eth0 file because with that i was unable to access my board from browser.

@yunqu br0 is showing there but now i am unable to access jupyter notebook from browser .

[jeffiy]

after trying i am able to solve connectivity issue with the following eth0 configuration.

But now when i run following code in jupyter notebook i got an Error shown on serial terminal.

Error shown on Serial port

[yunqu]

Kernel seems crashed. Maybe the br0 was assumed to be bridging on top of eth0 instead of the static eth0:1. Instead of trying to resolve this issue by yourself, is it possible to plug in an Ethernet cable to your board, and start over again? Just want to make sure this is actually working before you want to play around the static IP.

[jeffiy]

as per your instructions i tried it again by reinstalling but same issue that jupyter notebook is not accessible.

it am stuck in this issue since a month.
