-OrangePi PC
-
-Intro
-=====
-
-This default configuration will allow you to start experimenting with the
-buildroot environment for the OrangePi PC. With the current configuration
-it will bring-up the board, and allow access through the serial console.
-
-How to build it
-===============
-
-Configure Buildroot:
-
-    $ make orangepi_pc_defconfig
-
-Compile everything and build the SD card image:
-
-    $ make
-
-How to write the SD card
-========================
-
-Once the build process is finished you will have an image called "sdcard.img"
-in the output/images/ directory.
-
-Copy the bootable "sdcard.img" onto an SD card with "dd":
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX

+Raspberry Pi
+
+Intro
+=====
+
+These instructions apply to all models of the Raspberry Pi:
+  - the original models A and B,
+  - the "enhanced" models A+ and B+,
+  - the model B2 (aka Raspberry Pi 2)
+  - the model B3 (aka Raspberry Pi 3).
+  - the model B4 (aka Raspberry Pi 4).
+  - the model CM4 (aka Raspberry Pi Compute Module 4 and IO Board).
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+There are several Raspberry Pi defconfig files in Buildroot, one for
+each major variant, which you should base your work on:
+
+For models A, B, A+ or B+:
+
+  $ make raspberrypi_defconfig
+
+For model Zero (model A+ in smaller form factor):
+
+  $ make raspberrypi0_defconfig
+
+or for model Zero W (model Zero with wireless LAN and Bluetooth):
+
+  $ make raspberrypi0w_defconfig
+
+For model Zero 2 W (model B3 in smaller form factor):
+
+  $ make raspberrypizero2w_defconfig
+
+For model 2 B:
+
+  $ make raspberrypi2_defconfig
+
+For model 3 B and B+:
+
+  $ make raspberrypi3_defconfig
+
+or for model 3 B and B+ (64 bit):
+
+  $ make raspberrypi3_64_defconfig
+
+For model 4 B:
+
+  $ make raspberrypi4_defconfig
+
+or for model 4 B (64 bit):
+
+  $ make raspberrypi4_64_defconfig
+
+For model CM4 (on IO Board):
+
+  $ make raspberrypicm4io_defconfig
+
+or for CM4 (on IO Board - 64 bit):
+
+  $ make raspberrypicm4io_64_defconfig
+
+Build the rootfs
+----------------
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+You may now build your rootfs with:
+
+  $ make
+
+(This may take a while, consider getting yourself a coffee ;-) )
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:

+    output/images/

+
+[1] Not all of them will be present, depending on the RaspberryPi
+    model you are using.
+
+[2] Only for the Raspberry Pi 3/4 Models (overlay miniuart-bt is needed
+    to enable the RPi3 serial console otherwise occupied by the bluetooth
+    chip). Alternative would be to disable the serial console in cmdline.txt
+    and /etc/inittab.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the SDcard into your Raspberry Pi, and power it up. Your new system
+should come up now and start two consoles: one on the serial port on
+the P1 header, one on the HDMI output where you can login using a USB
+keyboard.
+
+How to write to CM4 eMMC memory
+===============================
+
+For CM4 modules without eMMC memory see above for booting from SD card,
+for CM4 modules with eMMC memory proceed as following:
+
+- fit jumper on IO Board header J2 to disable eMMC boot
+- connect IO Board micro USB port (J11 USB slave) to your host linux system
+- power up CM4/IO Board (lsusb command should show a '0a5c:2711 Broadcom Corp.
+  BCM2711 Boot' device)
+- run 'sudo ./host/bin/rpiboot', output should look like the following:
+    Waiting for BCM2835/6/7/2711...
+    Loading embedded: bootcode4.bin
+    Sending bootcode.bin
+    Successful read 4 bytes
+    Waiting for BCM2835/6/7/2711...
+    Loading embedded: bootcode4.bin
+    Second stage boot server
+    Loading embedded: start4.elf
+    File read: start4.elf
+    Second stage boot server done
+
+- a USB mass storage device should show up (the CM4 eMMC memory), proceed
+  as described above to copy sdcard.img to it
+- power down CM4/IO Board
+- remove jumper on IO Board header J2 to re-enable eMMC boot
+- power up CM4/IO Board
