| 3 | U-Boot for JetHub J100 |
| 4 | ======================= |
| 5 | |

| 28 | U-Boot compilation |
| 29 | ------------------ |
| 30 | |
| 31 | .. code-block:: bash |
| 32 | |
| 33 | $ export CROSS_COMPILE=aarch64-none-elf- |
| 34 | $ make jethub_j100_defconfig |
| 35 | $ make |
| 36 | |
| 37 | Image creation |
| 38 | -------------- |
| 39 | |
| 40 | Amlogic doesn't provide sources for the firmware and for tools needed |
| 41 | to create the bootloader image, so it is necessary to obtain binaries |
| 42 | from the git tree published by the board vendor: |
| 43 | |
| 44 | .. code-block:: bash |
| 45 | |
| 46 | $ git clone https://github.com/jethome-ru/jethub-aml-tools jethub-u-boot |
| 47 | $ cd jethub-u-boot |
| 48 | $ export FIPDIR=$PWD |
| 49 | |
| 50 | Go back to mainline U-boot source tree then : |
| 51 | |
| 52 | .. code-block:: bash |
| 53 | |
| 54 | $ mkdir fip |
| 55 | |
| 56 | $ cp $FIPDIR/j100/bl2.bin fip/ |
| 57 | $ cp $FIPDIR/j100/acs.bin fip/ |
| 58 | $ cp $FIPDIR/j100/bl21.bin fip/ |
| 59 | $ cp $FIPDIR/j100/bl30.bin fip/ |
| 60 | $ cp $FIPDIR/j100/bl301.bin fip/ |
| 61 | $ cp $FIPDIR/j100/bl31.img fip/ |
| 62 | $ cp u-boot.bin fip/bl33.bin |
| 63 | |
| 64 | $ $FIPDIR/blx_fix.sh \ |
| 65 | fip/bl30.bin \ |
| 66 | fip/zero_tmp \ |
| 67 | fip/bl30_zero.bin \ |
| 68 | fip/bl301.bin \ |
| 69 | fip/bl301_zero.bin \ |
| 70 | fip/bl30_new.bin \ |
| 71 | bl30 |
| 72 | |
| 73 | $ $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0 |
| 74 | |
| 75 | $ $FIPDIR/blx_fix.sh \ |
| 76 | fip/bl2_acs.bin \ |
| 77 | fip/zero_tmp \ |
| 78 | fip/bl2_zero.bin \ |
| 79 | fip/bl21.bin \ |
| 80 | fip/bl21_zero.bin \ |
| 81 | fip/bl2_new.bin \ |
| 82 | bl2 |
| 83 | |
| 84 | $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl30_new.bin \ |
| 85 | --output fip/bl30_new.bin.enc \ |
| 86 | --level v3 --type bl30 |
| 87 | $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl31.img \ |
| 88 | --output fip/bl31.img.enc \ |
| 89 | --level v3 --type bl31 |
| 90 | $ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl33.bin --compress lz4 \ |
| 91 | --output fip/bl33.bin.enc \ |
| 92 | --level v3 --type bl33 |
| 93 | $ $FIPDIR/j100/aml_encrypt_axg --bl2sig --input fip/bl2_new.bin \ |
| 94 | --output fip/bl2.n.bin.sig |
| 95 | $ $FIPDIR/j100/aml_encrypt_axg --bootmk \ |
| 96 | --output fip/u-boot.bin \ |
| 97 | --bl2 fip/bl2.n.bin.sig \ |
| 98 | --bl30 fip/bl30_new.bin.enc \ |
| 99 | --bl31 fip/bl31.img.enc \ |
| 100 | --bl33 fip/bl33.bin.enc --level v3 |
| 101 | |
| 102 | and then write the image to eMMC with: |
| 103 | |
| 104 | .. code-block:: bash |
| 105 | |
| 106 | $ DEV=/dev/your_emmc_device |
| 107 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 |
| 108 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444 |
