  1. Hi, I followed the instruction in https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-getting-started-with-microblaze-servers/start carefully to create the simple echo server with Nexys video board. The vivado version is 16.2. The Ethernet licence is evaluation version. After creating echo server application and run with SDK , it does not run as expected, the output is as follows: -----lwIP TCP echo server ------ TCP packets sent to port 6001 will be echoed back WARNING: Not a Marvell or TI Ethernet PHY. Please verify the initialization sequence
  2. Hi I want to utilize sdk to test echo server lwip,fpga program and run configration are done.However,in console,there are some lines make me confused. -----lwIP TCP echo server ------ TCP packets sent to port 6001 will be echoed back link speed: 1000 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 When I ping the board on PC,it displays "can't access the destination host" My board is Zybo.The hardware been built in vivado 2014.3.1 is a Zynq
  3. I setup my Nexys Video for the first time, and tried to setup an echo server using Vivado/SDK. I followed the following tutorial: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-getting-started-with-microblaze-servers/start When I go to generate a bitstream, I get the following error: [Common 17-69] Command Failed: This design contains one or more cells for which bitstream generation is not permitted: design_1_i/axi_ethernet_0_U0_mac_U0/tri_mode_ethernet_mac_i/bd_929b_mac_0_tri_mode_ethernet_mac_v9_0_12) If a new IP Core license was a
  4. Hello, I have been successful in running the lwIP echo server on the Zybo Z7 board. However, I want to develop a web server on Zynq. I have gone through the lwIP documentation. However, in the discussion of this topic, I was successful in reading the .bin file from the SD card. Now I want to set up a web server on Zynq so I can command the server to read the .bin file from SD card and store it in the DDR. How do I start working on the web server. I have been searching a lot for the tutorial or anything that could make me understand in a simpler way but I failed to find any.!
  5. Hello, I am running Vivado 18.1 and would like to try to get the echo server running by following this demo. I understand that the demo hasn't been verified on Vivado 18.1, but nevertheless I would like to try it. The only problem is that my block diagram doesn't quite match what is displayed on the demo screen shots, even though I have double checked the steps to create it. Is there a bd tcl file available to recreate this diagram for the demo. If not, can a higher resolution picture of the completed diagram be posted?
  6. Hi Mr./Ms., I have successfully make Nexys Video Microblaze server example works following: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-getting-started-with-microblaze-servers/start However, the echo server only works under standalone OS but not xilkernel OS. It gives me the error "unable to alloc pbuf in recv_handler" called from "setup_rx_bds" function, even I haven't telnet the server yet. I have tried: 1. increase heap size 2. increase pbuf_pool_buffer size, pbuf_pool_size 3. increase mem_size, mem_n_pbuf 4. enable jumbo
  7. Hi, In the SDK I have created the lwIP echo server project which builds OK. I have connected the Zybo to my laptop which has an IP address of 192.168.1.1 and subnet 255.255.255.0. Without using telnet or putty initially the terminal output is as follows. -----lwIP TCP echo server ------ TCP packets sent to port 6001 will be echoed back Start PHY autonegotiation Waiting for PHY to complete autonegotiation. Auto negotiation error Phy setup error Assert due to phy setup failure I have also tried to connect using putty before this timeout occurs but still unable to get e
  8. I was trying to run echo server example provided on digilent official website. The validation of block diagram is successful also HDL wrapper is successfully generated. Bit file generation is also completed and succefully exported to SDK without error, but while testing program on hardware it do not show any reception of packets. when we ping board status seems to be connected but console window in SDK do not show any details about connection. what are possible causes for error and solutions. console status: ping status: it should be like this:
