Environment Setup

Run this script to add necessary directoires to path

1. setup_env.sh

Build commands

Setup, download binary toolchain

1. ./build/setup.sh
2. cd docker, install Quartus (both QuartusLiteSetup and SoCEDSSetup, eventually this will be dockerized)

BSP (FPGA image and bootloaders, Linux kernel, root file system)

1. cd bsp
2. ./de10-nano-build.sh all

FPGA image and bootloaders only

1. cd bsp/de10-nano-hardware
2. make all
3. make sd-create-image-netboot (or sd-create-image to include fpga and device tree)

FPGA image

1. cd bsp/de10-nano-hardware
2. make rbf
3. make doesn't pickup all change, rm stamp/17.1/quartus.stamp if needed to trigger rebuild

Linux kernel and root file system

1. cd bsp/de10-nano-software
2. ./build.sh

Copy FPGA image, device tree, Linux, and root file system to tftp and nfs

1. cd bsp
2. ./build.sh copy_to_server

Copy bootloaders to sd card

1. dd if=sdcard-netboot.img of=/dev/mmcblk0 bs=2048
2. sync

Application Software

1. cd host/vxi11-cmd
2. make
3. cd host/vxi11-device-logic-analyzer
4. make

Simulation Commands

1. runSVUnit -t avalon_source_tester_unit_test.sv -s modelsim
2. Check console output
3. If needed, run vsim to open gui
