| 28 | U-Boot Compilation |
| 29 | ------------------ |
| 30 | |
| 31 | .. code-block:: bash |
| 32 | |
| 33 | $ export CROSS_COMPILE=aarch64-none-elf- |
| 34 | $ make beelink-gsking-x_defconfig |
| 35 | $ make |
| 36 | |
| 37 | U-Boot Signing with Pre-Built FIP repo |
| 38 | -------------------------------------- |
| 39 | |
| 40 | .. code-block:: bash |
| 41 | |
| 42 | $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1 |
| 43 | $ cd amlogic-boot-fip |
| 44 | $ mkdir my-output-dir |
| 45 | $ ./build-fip.sh beelink-s922x /path/to/u-boot/u-boot.bin my-output-dir |
| 46 | |
| 47 | U-Boot Manual Signing |
| 48 | --------------------- |
| 49 | |
| 50 | Beelink released an Amlogic "SDK" dump in their forums but the U-Boot sources included |
| 51 | result in 2GB RAM detected. The following FIPs were generated with newer sources and |
| 52 | detect 4GB RAM: https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x |
| 53 | |
| 54 | .. code-block:: bash |
| 55 | |
| 56 | $ wget https://github.com/LibreELEC/amlogic-boot-fip/archive/master.zip |
| 57 | $ unzip master.zip |
| 58 | $ export FIPDIR=$PWD/amlogic-boot-fip/beelink-s922x |
| 59 | |
| 60 | Go back to the mainline U-Boot source tree then: |
| 61 | |
| 62 | .. code-block:: bash |
| 63 | |
| 64 | $ mkdir fip |
| 65 | $ cp $FIPDIR/* fip/ |
| 66 | $ cp u-boot.bin fip/bl33.bin |

| 70 | fip/zero_tmp \ |
| 71 | fip/bl30_zero.bin \ |
| 72 | fip/bl301.bin \ |
| 73 | fip/bl301_zero.bin \ |
| 74 | fip/bl30_new.bin \ |

| 87 | --output fip/bl30_new.bin.g12a.enc \ |
| 88 | --level v3 |
| 89 | $ fip/aml_encrypt_g12b --bl3sig --input fip/bl30_new.bin.g12a.enc \ |
| 90 | --output fip/bl30_new.bin.enc \ |

| 93 | --output fip/bl31.img.enc \ |
| 94 | --level v3 --type bl31 |
| 95 | $ fip/aml_encrypt_g12b --bl3sig --input fip/bl33.bin --compress lz4 \ |
| 96 | --output fip/bl33.bin.enc \ |
| 97 | --level v3 --type bl33 |
| 98 | $ fip/aml_encrypt_g12b --bl2sig --input fip/bl2_new.bin \ |

| 114 | --level v3 |
| 115 | |
| 116 | Then write U-Boot to SD or eMMC with: |
| 117 | |
| 118 | .. code-block:: bash |
| 119 | |
| 120 | $ DEV=/dev/boot_device |
| 121 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 |
| 122 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=440 |
