arm64 update U-Boot on device (Rock64)

Method A

1.) Install Debian package for Rockchip U-Boot

sudo apt install u-boot-rockchip

2.) Flashing U-Boot to our Pine64 Rock64 SBC

lsblk		(remember storage device name --> mmcblk0 for instance)

sudo u-boot-install-rockchip /dev/mmcblkX

3.) Reboot the machine

sudo reboot

Method B

1.) Install Compiler for building U-Boot on our Pine64 Rock64 SBC

sudo apt install device-tree-compiler build-essential libssl-dev python3-dev bison
sudo apt install flex libssl-dev swig gcc-aarch64-linux-gnu gcc-arm-none-eabi
sudo apt install gcc make git python3-setuptools

2.) Build U-Boot on our Pine64 Rock64 SBC

cd /home
git clone https://github.com/ARM-software/arm-trusted-firmware
cd arm-trusted-firmware
git tag           (remember last stable --> lts-v2.12.1 for instance)
git checkout lts-v2.12.1
make PLAT=rk3328 bl31

cd ..

git clone git://git.denx.de/u-boot.git
cd u-boot
git tag           (remember last stable --> v2025.01 for instance)
git checkout v2025.01
ln -s /home/youruser/arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf bl31.elf
make BL31=bl31.elf rock64-rk3328_defconfig
make -j2 BL31=bl31.elf all u-boot.itb

cd ..

cp -r /home/youruser/u-boot/idbloader.img /home/youruser/
cp -r /home/youruser/u-boot/u-boot.itb /home/youruser/

3.) Flashing U-Boot to our Pine64 Rock64 SBC

cd /home/youruser/

lsblk             (remember storage device name --> mmcblk1 for instance)

sudo dd if=idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc
sudo dd if=u-boot.itb of=/dev/mmcblkX seek=16384 conv=notrunc

4.) Reboot the machine

sudo reboot

arm64 update U-Boot on device (H64B)

1.) Install Compiler for building U-Boot on our Pine64 H64B SBC

sudo apt install device-tree-compiler build-essential libssl-dev python3-dev bison
sudo apt install flex libssl-dev swig gcc-aarch64-linux-gnu gcc-arm-none-eabi
sudo apt install gcc make git python3-setuptools

2.) Build U-Boot on our Pine64 H64B SBC

cd /home
git clone https://github.com/ARM-software/arm-trusted-firmware
cd arm-trusted-firmware
git tag           (remember last stable --> lts-v2.12.1 for instance)
git checkout lts-v2.12.1
make PLAT=sun50i_h6 bl31

cd ..

git clone git://git.denx.de/u-boot.git
cd u-boot
git tag           (remember last stable --> v2025.01 for instance)
git checkout v2025.01
ln -s /home/youruser/arm-trusted-firmware/build/sun50i_h6/release/bl31/bl31.bin bl31.bin
make BL31=bl31.bin pine_h64_defconfig
make -j2 BL31=bl31.bin

cd ..

cp -r /home/youruser/u-boot/u-boot-sunxi-with-spl.bin /home/youruser/

3.) Flashing U-Boot to our Pine64 H64B SBC

cd /home/youruser/

lsblk             (remember storage device name --> mmcblk0 for instance)

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblkX bs=1024 seek=8 conv=notrunc

4.) Reboot the machine

sudo reboot

Note: Ignore the warning below, the just build u-boot image is still functional and will work.

Image 'u-boot-sunxi-with-spl' has faked external blobs and is non-functional: scp.bin

Image 'u-boot-sunxi-with-spl' is missing optional external blobs but is still functional: scp

/binman/u-boot-sunxi-with-spl/fit/images/scp/scp (scp.bin):
SCP firmware is required for system suspend, but is otherwise optional.
Please read the section on SCP firmware in board/sunxi/README.sunxi64

Some images are invalid
