This guide is the full manual install process. A scripted/automated install is available for Fates.

see Fates instructions if you're using a Fates board.

compile instructions for norns on raspberry pi with 4.14.y-rt

Starting from a fresh Stretch image (from etcher)

sudo raspi-config
	Change password: sleep
	Network > Hostname (norns)
	Interfacing > SSH (on)
	Interfacing > i2c (on)
	Interfacing > SPI (on)
	Advanced > Expand File System
	Localization > (en-US-UTF8, US-UTF8)
	Localization Options > Change Timezone
	Localization WiFi Country > Change Timezone	

Finish, Reboot

Change user name to we

sudo passwd root

logout, login as root (best to do this with keyboard directly connected)

usermod -l we -d /home/we -m pi
groupmod --new-name we pi

Exit, login as we (Can jump back to SSH here)

sudo passwd -l root

Disable need for passwd with sudo - look for 010_pi-nopasswd or similar

ls /etc/sudoers.d/
ssudo nano /etc/sudoers.d/010...

Change pi to we

Run updates, install git, build dependencies, etc

cd ~
sudo apt-get update 
sudo apt-get dist-upgrade
sudo apt-get install vim git bc i2c-tools 
sudo apt-get -y install libncurses5-dev 

git clone https://github.com/okyeron/norns-linux-bits.git

git clone --depth 1 --branch rpi-4.14.y-rt https://github.com/raspberrypi/linux
cd linux

we want commit hash 22bb67b8e2e809d0bb6d435c1d20b409861794d2 so...

git checkout 22bb67b8e2e809d0bb6d435c1d20b409861794d2

copy files from my drivers-staging-fbtft folder to


cp ~/norns-linux-bits/drivers-staging-fbtft/* /home/we/linux/drivers/staging/fbtft/
    

copy my bcm2709_defconfig from arch-arm-configs folder to

cp ~/norns-linux-bits/arch-arm-configs/bcm2709_defconfig /home/we/linux/arch/arm/configs/bcm2709_defconfig

(repalcing the one that's there)

copy my .config to

cp ~/norns-linux-bits/.config /home/we/linux/.config

Then compile

# Build kernel for Pi 2, Pi 3, Pi 3+ and Compute Module 3

cd ~/linux

export KERNEL=kernel7
make mrproper
make bcm2709_defconfig 


make modules_prepare

# just to check that CONFIG_FB_TFT_SSD1322=m
make menuconfig
        	Device Drivers  ---> Staging Drivers ---> Support for small TFT LCD display modules  --->
        	<M>   SSD1322 driver


make -j4 zImage modules dtbs
sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm/boot/zImage /boot/$KERNEL.img

and reboot

Test ssd1322: (adjust if using different GPIOs)

sudo modprobe fbtft_device custom name=fb_ssd1322 width=128 height=64 speed=16000000 gpios=reset:15,dc:14

lsmod to check loading should show

fb_ssd1322             16384  0
fbtft_device           49152  0
fbtft                  45056  2 fbtft_device,fb_ssd1322

con2fbmap 1 1 to show terminal console on OLED or con2fbmap 1 0 to go back to HDMI (fb0) - NOTE OLED will not clear until you reboot or do some other screen activity

Then copy overlay .dtbo files for norns

sudo cp ~/norns-linux-bits/overlays/norns-buttons-encoders.dtbo /boot/overlays
sudo cp ~/norns-linux-bits/overlays/ssd1322-fates.dtbo /boot/overlays/

See norns install instuctions for how to enable the ssd1322 in norns-image service modules.
