BUILD

On norns, toggle bottom PCB switch from RUN to DISK. Connect norns to linux computer via usb cable.

• download raspbian lite image: https://www.raspberrypi.org/downloads/raspbian/
• set up usbboot: https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md
• copy image to norns emmc, for example: sudo dd if=2017-11-29-raspbian-stretch-lite.img of=/dev/sdb bs=4MiB conv=fsync status=progress

Disconnect the boot USB port. Switch DISK back to RUN. Insert wifi.

Tape or weight down the power button. (Because a system file is not yet installed to keep the soft-power-switch on).

• connect to norns serial port: screen /dev/ttyUSB0 115200

The remaining commands happen within the terminal session:

login is "pi" with password "raspberry"

• sudo raspi-config

1. Change password: sleep
2. Network > Hostname (norns)
3. Network > Wifi (set SSID/password)
4. Interfacing > SSH (on)
5. Advanced > Expand File System
6. Localization > (set)
7. Exit, Reboot

• ctrl-A-Z will quit screen

re-login via ssh pi@norns.local (pw is now sleep)

continuing on within the ssh session:

run updates

• sudo apt-get update
• sudo apt-get upgrade
• sudo apt-get install vim git bc i2c-tools

update kernel

• get new kernel, put in linux computer TODO: get directly from gh

cd /
sudo tar -xvzf ~/kernel(...).tar.gz
sudo shutdown now

you can now remove the tape/weight from your power switch

change user name: we

1 sudo passwd root 2. logout, login as root 3. usermod -l we -d /home/we -m pi 4. groupmod --new-name we pi 5. exit, login as we 6. sudo passwd -l root

disable need for passwd with sudo

1. sudo nano /etc/sudoers.d/010_pi-nopasswd
2. change 'pi' to 'we'

clone norns-image for config setups

(this really needs to be done via screen not ssh because installing network-manager kills the wifi connection)

NOTE: buster branch of norns-image (to be commited to main)

git clone https://github.com/tehn/norns-image.git 
cd norns-image
./setup.sh

install norns

• TODO: remove some of this below?
• just copy norns/maiden/dust release folders.
• installing supercollider is the main thing.
• tons of recommends ie for libcairo2-dev

curl https://keybase.io/artfwo/pgp_keys.asc | sudo apt-key add -
echo "deb https://package.monome.org/ stretch main" | sudo tee /etc/apt/sources.list.d/norns.list
sudo apt update
sudo apt install --no-install-recommends jackd2 libjack-jackd2-dev
sudo apt install --no-install-recommends libmonome-dev libnanomsg-dev liblua5.3-dev libudev-dev libevdev-dev liblo-dev libcairo2-dev liblua5.3-dev libavahi-compat-libdnssd-dev libasound2-dev dnsmasq
sudo apt install --no-install-recommends supercollider-language supercollider-server supercollider-dev sc3-plugins
sudo apt install --no-install-recommends ladspalist usbmount

(clone your norns git)

cd norns
./waf configure
./waf
cd sc
./install.sh

note: you may need to run sclang once first (it will fail) before running norns/sc/install.sh

reboot, norns should boot up.

NOTE: alsamixer isn't turned up all the way. manually increase to 100

set up usbmount for SYNC/etc via menu:

(1) the 'usbmount' package is installed apt-get install usbmount

(2) MountFlags has been tweaked in systemd-udevd.service https://www.raspberrypi.org/forums/viewtopic.php?t=205016 (change MountFlags=slave to MountFlags=shared)
