use the uart port in nexys 4ddr board

Question

Hi
I designed a project in the Xilinx blocks then convert it to Vivado 2017.4 as IP, The problem is, i cant make synchronization between TX and RX by using the two FPGA Nexys4 DDR, Can I use the USB-UART Bridge (J6) to solve this problem? Note that neither microblaze nor the axi is used

Hi @shahad,

I split this thread here so we are not posting on a completed thread. 

Please attach screen shots of your block design and the  top, xdc  file.

Here is a VHDL Nexys 4 DDR project that uses the USB UART bridge. 

best regards,

Jon

Hi @jpeyron
Thank you very much for your response to my previous question, I have completed the design with the existence of MicroBlaze as shown in the Fig. below, but I need a code in the c language for MicroBlaze to complete the project please help me to get this code.
Thank you

Hi @shahad,

After looking at your original post again you should look at this forum thread about connecting two FPGA through USB UART connection.

Both of the Nexys 4 DRR usb uart bridges would be considered a downstream device. Neither of them have a USB Controller.

best regards,

Jon
