    Hi @Avinash,

    Welcome to the forums! I have not used Microblaze in a Zynq design as of yet. Here is a non-digilent tutorial Hello World on Microblaze UART on PS in Zynq Processor that discussed doing this that should be helpful.

    thank you,


    Thank you. This seems like a solution that could work. I am actually trying to get FreeRTOS on Microblaze in Zynq FPGA. Do you also have any references for me to achieve this.

    Sorry for confusing you, my answer was not quite correct.

    The UART in this case has nothing to do with the UCF or the schematic, it is entirely controlled from the ZYNQ PS.

    In order to use UART you will have to activate it in Vivado. Open the Block Design where you should see the ZYNQ PS, double click on it and then go to "MIO Configuration" and in the "I/O Peripherals" menu you have to check UART 1. UART 1 works on MIO 48 and 49.

    After that you can go to "PS-PL Configuration" -> General where you can set the baud rate.

    When this is completed you can go to SDK.



    I am also trying to use UART. But I want to access UART from the Microblaze instance of the Zybo FPGA. Please let me know how it can be done.
