$ export CROSS_COMPILE=aarch64-none-elf-
|
||
$ make odroid-go-ultra_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
