LWIP Echo Server Application on SDK 2016.2

LWIP echo server application provided with SDK 2016.2 fails to work on microblaze using axi ethernetlite IP. Not able to telnet into board eventhough the uart terminal shows all the valid print outs showing that application runs on the board. I am using VC707 evaluation kit.

Re: LWIP Echo Server Application on SDK 2016.2

Do you have your ehternet connection set up?. The connection may time out if Ethernet connection not setup or issue with ethernet cable
Thanks and Regards

Re: LWIP Echo Server Application on SDK 2016.2

hai

Sorry for the late reply. (Using SDK 2016.2 and Vivado 2016.2)

I am using VC707 Evaluation board . I am using axi ethernetlite IP and axi timer IP in my design. Both the interrupts are connected to interrupt controller using a concat and then the output of interrupt controller connected to Microblaze soft core processor. ethernetlite uses MII interface. The LWIP echo server applications prints all the messages including IP set for the board on the UART gtkterm terminal. Host PC and target board are connected using xilinx provided cross cable. Auto negotiation happens and set the speed to 100 Mbps and IP sets to 192.168.1.1 including all gateways etc. But there it ends . Not possible to even ping and hence telnet also saying Destination host unreachable. I am stuck with this.

Re: LWIP Echo Server Application on SDK 2016.2

Adding more to my recent posts....

The following prints on the uart terminal on running the LWIP echo server application on VC707 evaluation board.



-----lwIP TCP echo server ------
TCP packets sent to port 7 will be echoed back
auto-negotiated link speed: 100
DHCP Timeout
Configuring default IP of 192.168.1.10
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
TCP echo server started @ port 7

 

 

 

Afterwards ping and telnet also didn't work. I am stuck with this

 

Hoping some suggestions

 

 

With regards

Re: LWIP Echo Server Application on SDK 2016.2

This was never resolved... I'm seeing the same problem.

 

I have the microblaze configured for "Linux with MMU" and ran auto-connection wizard to do the memory setup. THen i used the Application Project in SDK for lwIP. As above, i get the UART message just fine but no echo. I have a 2014.4 project based on the lwIP that works but I'm trying to upgrade it to 2016.2 to match some other sample projects I need to use.

 

Thanks!

Re: LWIP Echo Server Application on SDK 2016.2

Hi I have exactly the same Problem when launching the echo server on the reference file of XAPP1026. I focused now on the DHCP Error. DCHP is automaticly activated if the IP adress is given automaticly in the WIN10 control panel. The XAPP1026 page 24 says it is possible to either deactivate DCHP in the BSP settings or launch a DCHP server on WIN10. Both dont work for me,

 

When i try to deactivate BSP in the socket_app_bsp (right click on the socket_apps_bsp folder in the project explorer then choose board support packages ) i get the attched error.

 

I am stuck at this too

Re: LWIP Echo Server Application on SDK 2016.2

Sorry to bother you,i just downloaded the lwip echo server example which is provided by vivado2014.3, and the documentation is XAPP1026. So where can i get the example provided by vivado2016 or vivado2016.

Thank you!
