U-Boot Compilation
------------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-none-elf-
$ make odroid-n2l_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 odroid-n2l /path/to/u-boot/u-boot.bin my-output-dir
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
