INTEL FPGA niosv_m
Overview
niosv_m board is based on Intel FPGA Design Store Nios® V/m Hello World Example Design system and this complete system is consisted of following IP blocks:
Nios® V/m Processor Intel® FPGA IP
JTAG UART Intel® FPGA IP
On-Chip Memory Intel® FPGA IP
Nios® V/m hello world example design system
Prebuilt Nios® V/m hello world example design system is available in Intel FPGA Design store. - https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/design-store.html?s=Newest
For example, Arria10 Nios® V/m processor example design system prebuilt files can be downloaded from following link. - https://www.intel.com/content/www/us/en/design-example/763960/arria10-niosv-based-helloworld-example-design-on-arria10-devkit.html?
ready_to_test/top.sof file is the prebuilt SRAM Object File for hello world example design system after the downloaded PAR files extracted successfully.
Create Nios® V/m processor example design system in FPGA
Please use Intel Quartus Programmer tool to program Nios® V/m processor based system into the FPGA and execute application.
In order to create the Nios® V/m processor inside the FPGA device, please download the generated .sof file onto the board with the following command.
quartus_pgm -c 1 -m JTAG -o "p;top.sof@1"
Note:
-c 1 is referring to JTAG cable number connected to the Host Computer.
@1 is referring to device index on the JTAG Chain and may differ for your board.
top.sof is referring to Nios® V/m processor based system SRAM Object File.
Download Zephyr elf file and run application
To download the Zephyr Executable and Linkable Format .elf file, please use the niosv-download command within Nios V Command Shell environment.
niosv-download -g <elf file>
Use the JTAG UART terminal to print the stdout and stderr of the Nios® V/m processor system.
