| 20 | U-Boot compilation |
| 21 | ------------------ |
| 22 | |
| 23 | .. code-block:: bash |
| 24 | |
| 25 | $ export CROSS_COMPILE=aarch64-none-elf- |
| 26 | $ make odroid-n2_defconfig |
| 27 | $ make |

| Neil Armstrong | 4c60512 | 2022-03-02 10:42:22 +0100 | [diff] [blame] | 32 | For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `odroid-n2` or `odroid-n2-plus` |
| 33 | |
| Neil Armstrong | 0ce3639 | 2020-06-11 10:53:49 +0200 | [diff] [blame] | 34 | Amlogic doesn't provide sources for the firmware and for tools needed |
| 35 | to create the bootloader image, so it is necessary to obtain them from |
| 36 | the git tree published by the board vendor: |
