| 3 | U-Boot for Beelink GT1 Ultimate (S912) |
| 4 | ====================================== |
| 5 | |
| 6 | Beelink GT1 Ultimate is an Android STB manufactured by Shenzen AZW (Beelink) with the |
| 7 | following specification: |
| 8 | |
| 9 | - 2GB or 3GB DDR3 RAM |
| 10 | - 32GB eMMC |
| 11 | - HDMI 2.1 video |
| 12 | - S/PDIF optical output |
| 13 | - 10/100/1000 Ethernet |
| 14 | - AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.2) |
| 15 | - 3x USB 2.0 ports |
| 16 | - IR receiver |
| 17 | - 1x micro SD card slot |
| 18 | - 1x Power LED (white) |
| 19 | - 1x Reset button (internal) |
| 20 | |
| 21 | The GT1 (non-ultimate) board has QCA9377 WiFi/BT but is otherwise identical and should |
| 22 | be capable of booting images prepared for the Ultimate box (NB: there are known clones |
| 23 | of both boxes which may differ in specifications). |
| 24 | |
| 25 | Beelink do not provide public schematics, but have been willing to share them with known |
| 26 | distro developers on request. |
| 27 | |
| 28 | U-Boot Compilation |
| 29 | ------------------ |
| 30 | |
| 31 | .. code-block:: bash |
| 32 | |
| 33 | $ export CROSS_COMPILE=aarch64-none-elf- |
| 34 | $ make beelink-gt1-ultimate_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-gt1 /path/to/u-boot/u-boot.bin my-output-dir |
| 46 | |
| 47 | U-Boot Manual Signing |
| 48 | --------------------- |
| 49 | |
| 50 | Amlogic does not provide firmware sources or tools needed to create the bootloader image |
| 51 | and Beelink has not publicly shared the U-Boot sources needed to build the FIP binaries |
| 52 | for signing. However you can download them from the amlogic-fip-repo. |
| 53 | |
| 54 | .. code-block:: bash |
| 55 | |
| 56 | $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1 |
| 57 | $ cd amlogic-boot-fip/beelink-gt1 |
| 58 | $ export FIPDIR=$PWD |
| 59 | |
| 60 | Go back to the mainline U-Boot source tree then: |
| 61 | |
| 62 | .. code-block:: bash |
| 63 | |
| 64 | $ mkdir fip |
| 65 | $ cp $FIPDIR/bl2.bin fip/ |
| 66 | $ cp $FIPDIR/acs.bin fip/ |
| 67 | $ cp $FIPDIR/bl21.bin fip/ |
| 68 | $ cp $FIPDIR/bl30.bin fip/ |
| 69 | $ cp $FIPDIR/bl301.bin fip/ |
| 70 | $ cp $FIPDIR/bl31.img fip/ |
| 71 | $ cp u-boot.bin fip/bl33.bin |
| 72 | |
| 73 | $ $FIPDIR/blx_fix.sh \ |
| 74 | fip/bl30.bin \ |
| 75 | fip/zero_tmp \ |
| 76 | fip/bl30_zero.bin \ |
| 77 | fip/bl301.bin \ |
| 78 | fip/bl301_zero.bin \ |
| 79 | fip/bl30_new.bin \ |
| 80 | bl30 |
| 81 | |
| 82 | $ python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0 |
| 83 | |
| 84 | $ $FIPDIR/blx_fix.sh \ |
| 85 | fip/bl2_acs.bin \ |
| 86 | fip/zero_tmp \ |
| 87 | fip/bl2_zero.bin \ |
| 88 | fip/bl21.bin \ |
| 89 | fip/bl21_zero.bin \ |
| 90 | fip/bl2_new.bin \ |
| 91 | bl2 |
| 92 | |
| 93 | $ $FIPDIR/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin |
| 94 | $ $FIPDIR/aml_encrypt_gxl --bl3enc --input fip/bl31.img |
| 95 | $ $FIPDIR/aml_encrypt_gxl --bl3enc --input fip/bl33.bin |
| 96 | $ $FIPDIR/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig |
| 97 | $ $FIPDIR/aml_encrypt_gxl --bootmk \ |
| 98 | --output fip/u-boot.bin \ |
| 99 | --bl2 fip/bl2.n.bin.sig \ |
| 100 | --bl30 fip/bl30_new.bin.enc \ |
| 101 | --bl31 fip/bl31.img.enc \ |
| 102 | --bl33 fip/bl33.bin.enc |
| 103 | |
| 104 | Then write U-Boot to SD or eMMC with: |
| 105 | |
| 106 | .. code-block:: bash |
| 107 | |
| 108 | $ DEV=/dev/boot_device |
| 109 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 |
| 110 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=440 |
