Hello, Using Vivado 17.4 I got the example to work with either 100 or 1000 mbps. I see a DHCP timeout in your post Please go to SDK in main.c and search for "dhcp_timoutcntr". You will find this variable set to 24. Please change it to 50 or 100 and try again. In some cases the counter expires before obtaining an IP and DHCP fails. You should also look in the MSS file (open with text editor) and search for " PARAMETER LIBRARY_NAME = lwip141". That is where the lwip settings are stored for the project. It should look like this: BEGIN LIBRARY PARAMETER LIBRARY_NAME = lwip141 PARAMETER LIBRARY_VER = 2.0 PARAMETER PROC_INSTANCE = microblaze_0 PARAMETER dhcp_does_arp_check = true PARAMETER lwip_dhcp = true PARAMETER phy_link_speed = CONFIG_LINKSPEED1000 END You can replace what you find with my settings (bolded lines) and then regenerate the bsp.

Hello, After connecting the board (prog port) and powering it on, how is the board recognized by the PC? Please check the USB tree and send us a screenshot. Sergiu

Hello,
I am trying to finish a project typically a USB to SPI convertor. i have written the code and simulated using modelsim (the code is just converting from usb to spi). The code does not contain enumeration process or any thing. My professor want me to do the hardware implementation using the Baysis3 board. In plain words, he want me to write my code to baysis board, send some data from PC to baysis3 board. It has to convert the received data into SPI protocols. Is there any scope for that.

Hello,
The basys3 can only receive data from a computer using UART. The micro-usb (prog) socket also doubles as a UART bridge. I believe you can see this in one of the Basys3 demo projects https://reference.digilentinc.com/basys3:basys3 .
in order to obtain SPI you will have to convert the data received from UART, which I believe is not what you want.

Hello Sergiu. We are new to Zybo. For some reason when we tried the second land tutorial in the FPGA Design Flow in Vivado workshop, we got an error message. Then, the Zybo no longer boots up. Did we unintentionally damage the board?

Thanks much for board geometry. Looking forward to using Arty. mulțumesc , Dave
