Hi,
I have a Zedboard and using the Xilinx SDK 2016.1 I have created an application project from the built-in template "FreeRTOS IwIP Echo Server". This template is found by selecting the freertos823_xilinx as the OS Platform option that the SDK gives you. This is a rather simple program, described as follows:
"The FreeRTOS lwIP Echo Server application provides a simple demonstration of how to use the light-weight IP stack (lwIP) with FreeRTOS. This application sets up the board to use IP address 192.168.1.10, with MAC address 00:0a:35:00:01:02. The server listens for input at port 7 and simply echoes back whatever data is sent to that port."
When I deploy on the hardware, I get the following:
-----lwIP Socket Mode Echo server Demo Application ------
Start PHY autonegotiation
ERROR: DHCP request timed out
Configuring default IP of 192.168.1.10
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
Server Port Connect With..
-------------------- ------ --------------------
echo server 7 $ telnet <board_ip> 7
The application then waits for connections, which I verified by adding some debug statements near the while loop where lwip_accept is executed. When I use TeraTerm from my Windows 7 host, I get "Connection timed out". I made sure the connection is to 192.168.1.10, port is 7, and I tried all the available Protocol options TeraTerm provides, and still the connection times out. I tried to connect using TeraTerm from another computer and get the same result. Could this be an incompatibility between the IP version of TeraTerm and IwIP?
Thanks.
