[Test setup (TFTP)](https://www.raspberrypi.com/documentation/computers/remote-access.html#test-setup)

Install fzf/zellij/zoxide

Download them from windows side - [zellij-aarch64-unknown-linux-musl.tar.gz](https://github.com/zellij-org/zellij/releases) - [fzf](https://github.com/junegunn/fzf/releases) - [zoxide](https://github.com/ajeetdsouza/zoxide/releases) - [neovim]() [share-files-with-scp](https://www.raspberrypi.com/documentation/computers/remote-access.html#share-files-with-scp)

scp fzf zellij zoxide rpi@impcas-ioc-rpi4-001.local:shared/

Or just use samba on windows side. ### Install nvim

sudo apt update
sudo apt install snapd
sudo reboot

sudo snap install snapd
sudo snap install --classic nvim

Network

~enable ipv4 on raspberrypi 3b with networkmanager (without raspi offical os)~

- [x] use `nmtui-edit` to modify `Wired Connection 1` located @ `system-connections/Wired\ connection\ 1.nmconnection `

rpi@<hidden>:/etc/NetworkManager $ sudo cat system-connections/Wired\ connection\ 1.nmconnection 

[connection]
id=Wired connection 1
uuid=<hidden>
type=ethernet
autoconnect-priority=-999
interface-name=<hidden>

[ethernet]

[ipv4]

may-fail=false
method=manual

[ipv6]
addr-gen-mode=default
method=disabled

[proxy]

- [ ] but how to automatically disable ipv6 when flashing os into sdcard?

rpi@<hidden>:/etc/NetworkManager/system-connections $ sudo cat preconfigured.nmconnection 
[connection]
id=preconfigured
uuid=<hidden>
type=wifi
[wifi]
mode=infrastructure
ssid=rfhjj
hidden=false
[ipv4]
method=auto
[ipv6]
addr-gen-mode=default
method=auto
[proxy]
[wifi-security]
key-mgmt=wpa-psk
psk=<hidden>

- [x] how to make mdns working - We need setup ipv4 first, use `nmtui-edit` then disable then enable connection by `nmtui` - https://wiki.archlinux.org/title/Avahi - In case you want to change mdns domain & host: `sudo vi /etc/avahi/avahi-daemon.conf`

epics on raspi

- [epics 7 installation](https://sfeister.github.io/sidekick-epics-docs/model1/pi-epics-install/) - [rpi epics](https://cmd-response.readthedocs.io/en/latest/epics/rpi_epics.html)

sudo apt -y install git net-tools build-essential re2c libnet-dev libpcap-dev libusb-1.0-0-dev

mkdir $HOME/EPICS
cd $HOME/EPICS
##git clone --recursive https://github.com/epics-base/epics-base.git
wget https://epics.anl.gov/download/base/base-7.0.8.1.tar.gz
tar xf base-7.0.8.1.tar.gz && ln -s base-7.0.8.1 epics-base
cd epics-base
make -j2 # rpi4b
~/EPICS/bin/linux-aarch64/caget

> [!IMPORTANT] > You need to set `PYEPICS_LIBCA` to load the correct `libca.so` on rpi > Refer to: [pyepics issue 238](https://github.com/pyepics/pyepics/issues/238)

cat >> ~/.bashrc << 'EOF'

softioc = [{ requirement = "epicscorelibs", match-runtime = true }]

uv pip install pvxslibs epicsdbbuilder pyyaml cothread

Then try with [this test](https://diamondlightsource.github.io/pythonSoftIOC/master/tutorials/creating-an-ioc.html). #### pcaspy on raspi

sudo apt install -y swig

source ~/.bashrc

uv pip install pcaspy
python -c "import pcaspy"

If encountered with: `ImportError: libca.so.4.14.3: cannot open shared object file: No such file or directory`, Check version first:

caget -V

ldd ~/.virtualenvs/ioc/lib/python3.12/site-packages/pcaspy/_cas.cpython-312-aarch64-linux-gnu.so

If epics version not matched with pcas build, then use `ln -s` to make softlinks for shared libs.

cd $EPICS_BASE/lib/linux-aarch64/
ln -s libca.so.4.14.4 libca.so.4.14.3
ln -s libCom.so.3.23.1 libCom.so.3.23.0

If encountered with: `ImportError: libdbCore.so.3.23.0: cannot open shared object file: No such file or directory`, need to reinstall pcaspy using pip:

 uv pip install --reinstall pcaspy  --no-cache
