| U-Boot compilation |
| ------------------ |
| |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-none-elf- |
| $ make jethub_j100_defconfig |
| $ make |
| |
| Image creation |
| -------------- |
| |
| Amlogic doesn't provide sources for the firmware and for tools needed |
| to create the bootloader image, so it is necessary to obtain binaries |
| from the git tree published by the board vendor: |
| |
| .. code-block:: bash |
| |
| $ git clone https://github.com/jethome-ru/jethub-aml-tools jethub-u-boot |
| $ cd jethub-u-boot |
| $ export FIPDIR=$PWD |
| |
| Go back to mainline U-boot source tree then : |
| |
| .. code-block:: bash |
| |
| $ mkdir fip |
| |
| $ cp $FIPDIR/j100/bl2.bin fip/ |
| $ cp $FIPDIR/j100/acs.bin fip/ |
| $ cp $FIPDIR/j100/bl21.bin fip/ |
| $ cp $FIPDIR/j100/bl30.bin fip/ |
| $ cp $FIPDIR/j100/bl301.bin fip/ |
| $ cp $FIPDIR/j100/bl31.img fip/ |
| $ cp u-boot.bin fip/bl33.bin |
| |
| $ $FIPDIR/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 |
| |
| $ $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0 |
| |
| $ $FIPDIR/blx_fix.sh \ |
| fip/bl2_acs.bin \ |
| fip/zero_tmp \ |
| fip/bl2_zero.bin \ |
| fip/bl21.bin \ |
| fip/bl21_zero.bin \ |
| fip/bl2_new.bin \ |
| bl2 |
| |
| $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl30_new.bin \ |
| --output fip/bl30_new.bin.enc \ |
| --level v3 --type bl30 |
| $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl31.img \ |
| --output fip/bl31.img.enc \ |
| --level v3 --type bl31 |
| $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl33.bin --compress lz4 \ |
| --output fip/bl33.bin.enc \ |
| --level v3 --type bl33 |
| $ $FIPDIR/j100/aml_encrypt_axg --bl2sig --input fip/bl2_new.bin \ |
| --output fip/bl2.n.bin.sig |
| $ $FIPDIR/j100/aml_encrypt_axg --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 --level v3 |
| |
| and then write the image to eMMC with: |
| |
| .. code-block:: bash |
| |
| $ DEV=/dev/your_emmc_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=444 |
