NEORV32 Xilinx Vivado Example Setups

How To Run

The create_project.tcl TCL script in the board subdirectories can be used for creating a complete Vivado project and for running the implementation. If not already available, this script will create a work folder in those subdirectories.

Note that you may need to install support for your particular development board through "XHub Stores" menu item within Vivado prior to sourcing the create_project.tcl script.

Batch mode

Execute vivado -mode batch -nojournal -nolog -source create_project.tcl from the board subdir. The project will be created and implementation will be run until generation of work/neorv32_test_setup.runs/impl_1/neorv32_test_setup.bit.

GUI

1. start Vivado (in GUI mode)
2. click on "TCL Console" at the bottom
3. use the console to naviagte to the boards folder. For example: cd .../neorv32/setups/vivado/arty-a7-test-setup
4. execute source create_project.tcl - this will create the actual Vivado project in work
5. when the Vivado project has openend, Implementation will run and a bitstream will be generated.
6. maybe a prompt will notify about it.

Programming the Bitstream

1. open the "Hardware Manager" (maybe a prompt will ask for that)
2. click on "Open target/Auto Connect"
3. click on "Program device" and select work/neorv32_test_setup.runs/impl_1/neorv32_test_setup.bit; click "Program"
4. use a serial terminal (like 🌏 Tera Term) to connect to the USB-UART interface using the following configuration: 19200 Baud, 8 data bits, 1 stop bit, no parity bits, no transmission / flow control protocol (raw bytes only), newline on \r\n (carriage return & newline)
5. now you can communicate with the bootloader console and upload a new program. Check out the example programs and see section "Let's Get It Started" of the 📄 NEORV32 data sheet for further resources.
