+U-Boot for BananaPi CM4 with CM4IO (A311D)
+==
+
+BPI-CM4 is a system-on-module board manufactured by Sinovoip. It follows the
Raspberry Pi
+CM4 interface specification but with a single HDMI port and a single DSI
output:
+
+ - Amlogic A311D Arm Cortex-A53 dual-core + Cortex-A73 quad-core SoC
+ - 4GB DDR4 SDRAM
+ - 16GB eMMC
+ - NPU
+ - HDMI 2.1 display
+ - Gigabit Ethernet
+ - RTL8822CS WiFi (a/b/g/n/ac) + BT 5.0
+
+BPI-CM4IO is a carrier board for the BPI-CM4 module with the following
specification:
+
+ - CM4 interface
+ - HDMI interface
+ - MIPI CSI interface
+ - MIPI DSI interface
+ - Ethernet interface
+ - PCIe interface
+ - SD (micro)
+ - SIM (micro)
+ - 26-pin GPIO
+ - UART serial
+ - 1x USB-C (power)
+ - 2x USB 2.0
+
+Schematics are available from the manufacturer:

+U-Boot Signing with Pre-Built FIP repo

+U-Boot Manual Signing
+-
+
+Amlogic does not provide sources for the firmware and tools needed to create a
bootloader
+image so it is necessary to obtain binaries from sources published by the
board vendor:
+
+.. code-block:: bash
+
+$ wget
https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+$ wget
https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+$ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+$ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+$ export
PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
+
+$ DIR=bananapi-cm4io
+$ git clone --depth 1 https://github.com/Dangku/amlogic-u-boot.git -b
khadas-g12b-v2015.01-m2s $DIR
+
+$ cd $DIR
+$ make bananapi_cm4_defconfig
+$ make
+$ export UBDIR=$PWD
+
+Go back to the mainline U-Boot source tree then:
+
+.. code-block:: bash
