Installation

1. Download Raspbian Stretch Lite from https://www.raspberrypi.org/downloads/raspbian/

2. Copy to SD card (> 4GB)

   dd if=/home/niklas/Downloads/2017-11-29-raspbian-stretch-lite.img | pv | dd of=/dev/sdb
   sync

3. Plug SD card in your Pi and power it up. Wait for a few minutes.

4. Plug the SD card back to your PC. Mount the boot partition and edit the "config.txt". Go to the bottom and add:

   dtoverlay=dwc2as

   #Overscan Information.
   #overscan_left=-32
   #overscan_right=-32
   overscan_top=10
   #overscan_bottom=-32
   framebuffer_width=960
   framebuffer_height=160
   

   #Enable the lcd, enable custom display sizes with CVT, set as the default >output.
   enable_dpi_lcd=1
   dpi_group=2
   dpi_mode=87 # Hdmi CVT
   display_default_lcd=1
   

   dpi_output_format=458773
   hdmi_timings=960 0 40 48 88 160 0 13 3 32 0 0 0 60 0 32000000 3
   

5. Save the config.txt file as plain text and then open "cmdline.txt". After rootwait (the last word on the first line) add a space and then

   modules-load=dwc2,g_ether

6. Enable SSH. Create a empty file named "ssh" on the boot partition:

   echo "" > /boot/ssh

7. Plug in your Pi with a USB Micro cable. Make sure to use the "USB" plug.

8. SSH to your Pi, connected as a network device:

   ssh [email protected]

9. Expand the filesystem using the raspi tool

   sudo raspi-config

10. On your Pi, install and download few tools. Make sure to share internet with your Pi:

    sudo apt-get install device-tree-compiler
    wget https://raw.githubusercontent.com/NiklasFauth/pollin-lcd-dpi/master/pollin-dt-blob.dts

11. Create a device-tree file that enables all the required GPIOs:

    sudo dtc -I dts -O dtb -o /boot/dt-blob.bin pollin-dt-blob.dts

12. Reboot.
