Upsilon docker development environment setup.
|
||||
|
||||
# Dockerfile style guide
|
||||
|
||||
Dockerfiles should be simple. The Dockerfiles should be readable to a
|
||||
beginner.
|
||||
|
||||
# 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.
|
||||
|
||||
If you have issues with docker, try adding to `~/.config/docker/daemon.json`
|
||||
|
||||
{
|
||||
"storage-driver": "fuse-overlayfs"
|
||||
}
|
||||
|
||||
|
||||
## Download and Install Python3
|
||||
|
||||
Install `python3` and `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.
|
||||
|
||||
## 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 `192.168.1.100/24`, netmask `255.255.255.0`,
|
||||
gateway `192.168.1.1`. Make sure this is not the default route. Make sure
|
||||
to adjust your firewall to allow traffic on the 192.168.1.0/24 range.
|
||||
|
||||
If your local network already uses the 192.168.1.0/24 range, then you must
|
||||
modify `upsilon/firmware/soc.py` to use different IPs. You must rebuild the
|
||||
SoC after doing this.
|
||||
|
||||
## 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 artefacts.
|
||||
|
||||
If you do not delete the container you can run
|
||||
|
||||
make $NAME-copy $NAME-execute $NAME-get
|
||||
|
||||
when you need to rebuild. If you need shell access, run `make $NAME-shell`.
|
||||
|
||||
## Launch TFTP Server
|
||||
|
||||
Install py3tftp (`pip3 install --user py3tftp`). Then run `make tftp` to
|
||||
launch the TFTP server. Keep this terminal open.
|
||||
|
||||
## Flash FPGA
|
||||
|
||||
Plug in your FPGA into the USB slot. If you have installed openFPGALoader
|
||||
by your package manager, run `make OPENFPGALOADER=openfpgaloader flash`.
|
||||
If you installed it using `make openFPGALoader`, then just run `make flash`.
|
||||
|
||||
In a second you should see messages in the TFTP terminal. This means your
|
||||
controller is sucessfully connected to your computer.
|
||||
|
||||
## SSH Access
|
||||
|
||||
Add the following to your SSH config:
|
||||
|
||||
Host upsilon
|
||||
HostName 192.168.1.50
|
||||
StrictHostKeyChecking no
|
||||
UserKnownHostsFile /dev/null
|
||||
IdentityFile upsilon_key
|
||||
User root
|
||||
LogLevel QUIET
|
||||
|
||||
Then copy the file `build/upsilon_key` to `$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`.
