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

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

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.
