Running a Design on Nexys Video
|
|
===============================
|
|
|
|
Nexys Video Instructions
|
|
------------------------
|
|
|
|
The default Digilent Nexys Video harness uses a TSI-over-UART adapter to bringup the FPGA.
|
|
A user can connect to the Nexys Video target using a special ``uart_tsi`` program that opens a UART TTY.
|
|
The interface for the ``uart_tsi`` program provides unique functionality that is useful for bringing up test chips.
|
|
|
|
To build the design (Vivado should be added to the ``PATH``), run:
|
|
|
|
.. code-block:: shell
|
|
|
|
cd fpga/
|
|
make SUB_PROJECT=nexysvideo bitstream
|
|
|
|
To build the UART-based frontend server, run:
|
|
|
|
.. code-block:: shell
|
|
|
|
cd generators/testchipip/uart_tsi
|
|
make
|
|
|
|
After programming the bitstream, and connecting the Nexys Video's UART to a host PC via the USB cable, the ``uart_tsi`` program can be run to interact with the target.
|
|
|
|
Running a program:
|
|
|
|
.. code-block:: shell
|
|
|
|
./uart_tsi +tty=/dev/ttyUSBX dhrystone.riscv
|
|
|
|
Probe an address on the target system:
|
|
|
|
.. code-block:: shell
|
|
|
|
./uart_tsi +tty=/dev/ttyUSBX +init_read=0x10040 none
|
|
|
|
Write some address before running a program:
|
|
|
|
.. code-block:: shell
|
|
|
|
./uart_tsi +tty=/dev/ttyUSBX +init_write=0x80000000:0xdeadbeef none
|
|
|
|
Self-check that binary loading proceeded correctly:
|
|
|
|
.. code-block:: shell
|
|
|
|
./uart_tsi +tty=/dev/ttyUSBX +selfcheck dhrystone.riscv
|
