U-Boot for Radxa Zero2 (A311D)
|
|
==============================
|
|
|
|
Radxa Zero2 is a small form factor SBC based on the Amlogic A311D chipset with the
|
|
following specification:
|
|
|
|
- Amlogic A311D (Quad A73 + Dual A53) CPU
|
|
- 4GB LPDDR4 RAM
|
|
- 32/64/128GB eMMC
|
|
- Mali G52-MP4 GPU
|
|
- HDMI 2.1 output (micro)
|
|
- BCM4345 WiFi (2.4/5GHz a/b/g/n/ac) and BT 5.0
|
|
- 1x USB 2.0 port - Type C (OTG)
|
|
- 1x USB 3.0 port - Type C (Host)
|
|
- 1x micro SD Card slot
|
|
- 40 Pin GPIO header
|
|
|
|
Schematics are available on request from Radxa.

U-Boot Compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make radxa-zero2_defconfig
|
|
$ make
|
|
|
|
U-Boot Signing with Pre-Built FIP repo
|
|
--------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
|
|
$ cd amlogic-boot-fip
|
|
$ mkdir my-output-dir
|
|
$ ./build-fip.sh radxa-zero2 /path/to/u-boot/u-boot.bin my-output-dir
|
|
|
|
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
|
|
|
|
$ git clone -b radxa-zero-v2021.07 https://github.com/radxa/u-boot.git
|
|
$ git clone https://github.com/radxa/fip.git
|
|
|
|
$ sudo apt-get install -y gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev
|
|
$ sudo apt-get install -y bc python dosfstools flex build-essential libssl-dev mtools
|
|
|
|
$ wget https://developer.arm.com/-/media/Files/downloads/gnu-a/10.3-2021.07/binrel/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf.tar.xz
|
|
$ sudo tar xvf gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf.tar.xz -C /opt
|
|
|
|
$ export CROSS_COMPILE=/opt/gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf/bin/aarch64-none-elf-
|
|
$ export ARCH=arm
|
|
$ cd u-boot
|
|
$ make radxa-zero2_defconfig
|
|
$ make
|
|
|
|
$ cp u-boot.bin ../fip/radxa-zero2/bl33.bin
|
|
$ cd ../fip/radxa-zero2
|
|
$ make
|
|
|
|
This will generate the signed U-Boot binaries:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ u-boot.bin u-boot.bin.sd.bin u-boot.bin.usb.bl2 u-boot.bin.usb.tpl
|
|
|
|
Then write U-Boot to SD or eMMC with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/boot_device
|
|
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
|
|
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=440
