UART connection on Zedboard

cascade99

Hi,
I followed instruction from the following link to try get UART work, I installed the driver and I could see it from the device manager, but there is no print out on HyperTerminal:

http://zedboard.org/content/zedboard-sdk-helloworld-example

I'm wondering by default of zedboard, UART is connect to the cortex? do I need do wiring for the connection?

Or there is other example I can try the UART connection?

Thanks

    Hello Lynn,

     

    From the information you listed in a previous post I am going to assume that you are using a current version of the Xilinx Vivado tools and that you ZedBoard hardware works (that you do get an output on your HyperTerminal with your FreeRTOS application). If this is not the case let us know. It the future if you can supply the basic information, such as Xilinx tool suite used, host OS, etc. it will be easier to provide assistance.

     

    The link you reference above if pretty old and targets the older PlanAhead/ISE tools suite, so I would use an example that targets the current Vivado tools.  There are several examples on our ZedBoard Reference Designs page:

    Or you can use the MicroZed tutorials we discussed in the previous forum thread and just target the ZedBoard instead. Tutorials 01 and 02 should get you there:

    http://zedboard.org/support/design/1519/10

     

    As for the basics your design should provide output to the USB UART as long as you have included UART1 in your hardware design but not UART0 (this is the default configuration). If you enable UART0 in your design the application will use UART0 as the default unless you change the settings in the BSP. If you want to make sure it is not your hardware design that is causing the issue you can use the pre-defined zed_hw_platform hardware platform in the SDK. Just start with the SDK and when interacting with the new Application Project dialog select 'zed_hw_platform' as the Hardware Platform and make sure 'Create New' is selected for the BSP.
