Upsilon docker development environment setup
|
|
|
|
# Docker Guide
|
|
|
|
This guide is tailored toward a Debian-based machine (and tested on Debian 12).
|
|
However, because most of the build process occurs within Docker containers,
|
|
this guide should be easily adopted to run in nearly any modern Linux environment.
|
|
|
|
# Setup steps
|
|
|
|
Do all of the following in the `build` folder.
|
|
|
|
## Installing OpenFPGALoader
|
|
|
|
Install [openFPGALoader][1]. If this program is not in your repositories,
|
|
run `make openFPGALoader` to fetch and build the program. This will install
|
|
openFPGALoader locally.
|
|
|
|
Even if you install openFPGALoader locally, there are some files (udev rules)
|
|
that must be installed with administrative privleges. Check the documentation
|
|
for openFPGALoader.

|
## Setup Rootless Docker
|
|
|
|
Docker allows you to run programs in containers, which are isolated
|
|
environments. Build environments can be set up automatically, and re-setup
|
|
whenever needed.
|
|
|
|
To install Docker, run:
|
|
```bash
|
|
sudo apt install docker.io docker-compose
|
|
```
|
|
|
|
Next, using [this guide][2], create a `docker` group and add your user to
|
|
that group. This will allow you to run docker commands without needing to run
|
|
them as root each time.
|
|
|
|
If you have issues with docker, try adding to `~/.config/docker/daemon.json`
|
|
|
|
{
|
|
"storage-driver": "fuse-overlayfs"
|
|
}
|
|
|
|
|
|
## Download and Install Python3
|
|
|
|
Install `python3-venv` (or `python3-virtualenv`) and `python3-pip`:
|
|
```bash
|
|
sudo apt install python3-venv python3-pip
|
|
```
|
|
|
|
## Clone External Repositories
|
|
|
|
Run `make clone`. You may need to download the upsilon repositories
|
|
and put them in the same folder as the Makefile.
|
|
|
|
Note: If `make` is not already installed, you can install it by running the following
|
|
command:
|
|
```bash
|
|
sudo apt install build-essential
|
|
```
|
|
|
|
## Setup Network
|
|
|
|
Plug in your router/switch to an ethernet port on your computer. If your
|
|
computer is usually wired to the network, you will need another ethernet
|
|
port (a PCI card is ideal, but a USB-Ethernet port works).
|
|
|
|
Set the ethernet port to static ip `192.168.2.100/24`, netmask `255.255.255.0`,
|
|
gateway `192.168.2.1`. Make sure this is not the default route. Make sure
|
|
to adjust your firewall to allow traffic on the `192.168.2.0/24` range.
|
|
|
|
If your local network already uses the `192.168.2.0/24` range, then you must
|
|
modify `upsilon/gateware/soc.py` to use different IPs. You must rebuild the
|
|
SoC after doing this.
|
|
|
|
The controller boots using TFTP with port `6969`. If you cannot use this
|
|
port, you can modify `upsilon/gateware/soc.py` to a different value. This value
|
|
is hardcoded into the SoC and any change to it requires a rebuild of the SoC.
|
|
You must also change the port in `upsilon/build/Makefile` under `tftp`.
|
|
|
|
## Setup Images
|
|
|
|
Run `make images` to create all docker images.
|
|
|
|
## Setup and Run Containers
|
|
|
|
For `NAME` in `hardware`, `opensbi`, `buildroot`:
|
|
|
|
1. Run `make $NAME-container` to build the container. You usually only need
|
|
to do this once.
|
|
2. If the container already exists, do `docker container start upsilon-$NAME`.
|
|
3. Run `make $NAME-copy` to copy Upsilon's code into the container.
|
|
4. Run `make $NAME-execute` to build the data.
|
|
5. Run `make $NAME-get` to retrieve the build artifacts.
|
|
|
|
If you do not delete the container you can run the following when you need to rebuild:
|
|
|
|
```bash
|
|
make $NAME-copy $NAME-execute $NAME-get
|
|
```
|
|
|
|
If you need shell access, run `make $NAME-shell`.
|
|
|
|
Run `make $NAME-clean` to delete the container.
|
|
|
|
## Launch TFTP Server
|
|
|
|
Install py3tftp (`pip3 install --user py3tftp`). Then run `make tftp` to
|
|
launch the TFTP server. Keep this terminal open.
|
|
|
|
## Flash FPGA
|
|
|
|
Plug in your FPGA into the USB slot. If you have installed openFPGALoader
|
|
by your package manager, run `make flash`. If you compiled openFPGALoader using
|
|
`make openFPGALoader`, the makefile will automatically use this instance. Otherwise,
|
|
it will attempt to use the openFPGALoader version installed through the package manager.
|
|
|
|
In a second you should see messages in the TFTP terminal. This means your
|
|
controller is sucessfully connected to your computer.
|
|
|
|
## SSH Access
|
|
|
|
Add the following to your SSH config:
|
|
|
|
Host upsilon
|
|
HostName 192.168.2.50
|
|
StrictHostKeyChecking no
|
|
UserKnownHostsFile /dev/null
|
|
IdentityFile upsilon_key
|
|
User root
|
|
LogLevel QUIET
|
|
|
|
Then copy the file `build/upsilon_key` to `$HOME/.ssh`.
|
|
|
|
When the FPGA is connected you can access it with `ssh upsilon` (password
|
|
`upsilon`).
|
|
|
|
Wait about a minute for Linux to boot.
|
|
|
|
## Launch FPGA Shell (Optional)
|
|
|
|
If you cannot access the FPGA through SSH, you can launch a shell through
|
|
UART.
|
|
|
|
You will need to install [LiteX](https://github.com/enjoy-digital/litex).
|
|
Download and run `litex_setup.py`.
|
|
|
|
Run `litex_term /dev/ttyUSB1`. You should get messages in the window with
|
|
the TFTP server that the FPGA has connected to the server. Eventually you
|
|
will get a login prompt (username `root` password `upsilon`).
|
|
|
|
## Copy Library
|
|
|
|
Run `make copy` to copy the Micropython Upsilon library to the FPGA. After
|
|
this the modules `comm` and `mmio` are available when running scripts in
|
|
`/root`.
