U-Boot for Radxa Zero
|
|
=====================
|
|
|
|
Radxa Zero is a small form factor SBC based on the Amlogic S905Y2
|
|
chipset that ships in a number of RAM/eMMC configurations:
|
|
|
|
Boards with 512MB/1GB LPDDR4 RAM have no eMMC storage and BCM43436
|
|
wireless (2.4GHz b/g/n) while 2GB/4GB boards have 8/16/32/64/128GB
|
|
eMMC storage and BCM4345 wireless (2.4/5GHz a/b/g/n/ac).
|
|
|
|
- Amlogic S905Y2 quad-core Cortex-A53
|
|
- Mali G31-MP2 GPU
|
|
- HDMI 2.1 output (micro)
|
|
- 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 the manufacturer website:

U-Boot compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make radxa-zero_defconfig
|
|
$ make
|
|
|
|
Image creation
|
|
--------------
|
|
|
|
For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `radxa-zero`
|
|
|
|
Amlogic does not provide sources for the firmware and for tools needed
|
|
to create the bootloader image, so it is necessary to obtain them from
|
|
git trees 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-zero_defconfig
|
|
$ make
|
|
|
|
$ cp u-boot.bin ../fip/radxa-zero/bl33.bin
|
|
$ cd ../fip/radxa-zero
|
|
$ make
|
|
|
|
This will generate:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ u-boot.bin u-boot.bin.sd.bin u-boot.bin.usb.bl2 u-boot.bin.usb.tpl
|
|
|
|
Then write the image to SD with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/your_sd_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=444
