| U-Boot Compilation |
| ------------------ |
| |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-none-elf- |
| $ make beelink-gtkingpro_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 beelink-s922x /path/to/u-boot/u-boot.bin my-output-dir |
| |
| U-Boot Manual Signing |
| --------------------- |
| |
| Beelink released an Amlogic "SDK" dump in their forums, but the U-Boot sources included |
| result in 2GB RAM detected. The following FIPs were generated with newer sources and |
| detect 4GB RAM: https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x |
| |
| .. code-block:: bash |
| |
| $ wget https://github.com/LibreELEC/amlogic-boot-fip/archive/master.zip |
| $ unzip master.zip |
| $ export FIPDIR=$PWD/amlogic-boot-fip/beelink-s922x |
| |
| Go back to the mainline U-Boot source tree then: |
| |
| .. code-block:: bash |
| |
| $ mkdir fip |
| $ cp $FIPDIR/* fip/ |
| $ cp u-boot.bin fip/bl33.bin |
| |
| $ sh fip/blx_fix.sh \ |
| fip/bl30.bin \ |
| fip/zero_tmp \ |
| fip/bl30_zero.bin \ |
| fip/bl301.bin \ |
| fip/bl301_zero.bin \ |
| fip/bl30_new.bin \ |
| bl30 |
| |
| $ sh fip/blx_fix.sh \ |
| fip/bl2.bin \ |
| fip/zero_tmp \ |
| fip/bl2_zero.bin \ |
| fip/acs.bin \ |
| fip/bl21_zero.bin \ |
| fip/bl2_new.bin \ |
| bl2 |
| |
| $ fip/aml_encrypt_g12b --bl30sig --input fip/bl30_new.bin \ |
| --output fip/bl30_new.bin.g12a.enc \ |
| --level v3 |
| $ fip/aml_encrypt_g12b --bl3sig --input fip/bl30_new.bin.g12a.enc \ |
| --output fip/bl30_new.bin.enc \ |
| --level v3 --type bl30 |
| $ fip/aml_encrypt_g12b --bl3sig --input fip/bl31.img \ |
| --output fip/bl31.img.enc \ |
| --level v3 --type bl31 |
| $ fip/aml_encrypt_g12b --bl3sig --input fip/bl33.bin --compress lz4 \ |
| --output fip/bl33.bin.enc \ |
| --level v3 --type bl33 |
| $ fip/aml_encrypt_g12b --bl2sig --input fip/bl2_new.bin \ |
| --output fip/bl2.n.bin.sig |
| $ fip/aml_encrypt_g12b --bootmk \ |
| --output fip/u-boot.bin \ |
| --bl2 fip/bl2.n.bin.sig \ |
| --bl30 fip/bl30_new.bin.enc \ |
| --bl31 fip/bl31.img.enc \ |
| --bl33 fip/bl33.bin.enc \ |
| --ddrfw1 fip/ddr4_1d.fw \ |

| --ddrfw7 fip/diag_lpddr4.fw \ |
| --ddrfw8 fip/aml_ddr.fw \ |
| --level v3 |
| |
| 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 |
