| 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 |
