Dual EVG

Gateware/Software for Dual EVG

Building

This repository contains both gateware and software for the Dual EVG.

Gateware Dependencies

To build the gateware the following dependencies are needed:

• GNU Make
• Xilinx Vivado (2020.2.2 tested), available here
• Xilinx Vitis (2020.2.2 tested), available here

Make sure vivado and vitis are in PATH.

Software Dependencies

To build the software the following dependencies are needed:

• mb-gcc toolchain, bundled within Vitis

Building Instructions

With the dependencies in place a simple make should be able to generate both gateware and software:

make

A suggestion in running the make command is to measure the time and redirect stdout/stderr to a file so you can inspect it later:

ARM_TOOLCHAIN_LOCATION=/media/Xilinx/Vivado/2020.2.2/Vitis/2020.2/gnu/microblaze/lin
(time make CROSS_COMPILE=${ARM_TOOLCHAIN_LOCATION}/bin/mb- APP=devg PLATFORM=marble && notify-send 'Compilation SUCCESS' || notify-send 'Compilation ERROR'; date) 2>&1 | tee make_output

For now the following APPs are supported:

• devg
• devg_test

Deploying

To deploy the gateware and the software we can use a variety of methods. For development, JTAG is being used.

The following script can download the gateware/software via JTAG:

cd scripts
./deploy.sh software/app/<APP>/download.bit

Usually, APP=devg or APP=devg_test depending on the desired target.
