UART application

Former Member

Dear all,
I'm new to Microzed and I need to use UART communication for my project. I need to get data using the UART and I cannot found any tutorial that helps me to set the UART. I already found example from Xilinx but it is not working. Any idea where I can get the tutorial to setting the UART?

    So if I understand correctly you are using a MicroZed board and have added an axi_uartlite core to your Zynq Programmable Logic (PL) section and connected it via an axi_interconnect core to the Zynq processor, and connected the interrupt from the axi_uartlite core to a Zynq PS interrupt that you have enabled. How have you connected the uartlite rx and tx signals to your external device? The Pmod port on the MicroZed is only connected to Zynq MIO pins and so cannot provide a connection from PL based peripherals. Are you using a carrier card?

     

    If you have built this hardware and exported to SDK I would first verify that it works in non-interrupt mode.

     

    Once these steps verify your hardware design we can start to debug interrupt based operation.
