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:

update kernel

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

sudo tar -xvzf ~/kernel(...).tar.gz
sudo cp -R boot/* /boot/
sudo cp -R lib/* /lib/
sudo shutdown now

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

run updates

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

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 vim /etc/sudoers.d/010_pi-nopasswd
2. change 'pi' to 'we'
3. force write with :w!

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

sc3-plugins

install norns

• just copy norns/maiden/dust release folders.

(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.

FIX NETWORK MANAGER (for shields)

edit /etc/dhcpcd.conf --- add denyinterfaces wlan0 edit /etc/NetworkManager/NetworkManager.conf to be:

[main]
plugins=ifupdown,keyfile
dhcp=internal

[ifupdown]
managed=true
