| 3 | U-Boot for Beelink GT-King |
| 4 | ========================== |
| 5 | |
| 6 | The Shenzen AZW (Beelink) GT-King is based on the Amlogic W400 reference |
| 7 | board with an S922X-H chip. |
| 8 | |
| 9 | - 4GB LPDDR4 RAM |
| 10 | - 64GB eMMC storage |
| 11 | - 10/100/1000 Base-T Ethernet |
| 12 | - AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.1) |
| 13 | - HDMI 2.1 video |
| 14 | - S/PDIF optical output |
| 15 | - Analogue audio output |
| 16 | - 1x USB 2.0 port |
| 17 | - 2x USB 3.0 ports |
| 18 | - IR receiver |
| 19 | - 1x micro SD card slot |
| 20 | |
| 21 | Beelink do not provide public schematics, but have been willing |
| 22 | to share them with known distro developers on request. |
| 23 | |
| 24 | U-Boot compilation |
| 25 | ------------------ |
| 26 | |
| 27 | .. code-block:: bash |
| 28 | |
| 29 | $ export CROSS_COMPILE=aarch64-none-elf- |
| 30 | $ make beelink-gtking_defconfig |
| 31 | $ make |
| 32 | |
| 33 | Image creation |
| 34 | -------------- |
| 35 | |
| 36 | Amlogic does not provide sources for the firmware and for tools needed |
| 37 | to create the bootloader image. Beelink have provided the Amlogic "SDK" |
| 38 | in their forums, but the u-boot sources included result in 2GB RAM being |
| 39 | detected. The following FIPs were generated with newer private sources |
| 40 | and give correct (4GB) RAM detection: |
| 41 | |
| 42 | https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x |
| 43 | |
| 44 | NB: Beelink use a common board config for GT-King, GT-King Pro and the |
| 45 | GS-King-X model, hence the "beelink-s922x" name. |
| 46 | |
| 47 | .. code-block:: bash |
| 48 | |
| 49 | $ wget https://github.com/LibreELEC/amlogic-boot-fip/archive/master.zip |
| 50 | $ unzip master.zip |
| 51 | $ export FIPDIR=$PWD/amlogic-boot-fip/beelink-s922x |
| 52 | |
| 53 | Go back to the mainline U-Boot source tree then: |
| 54 | |
| 55 | .. code-block:: bash |
| 56 | |
| 57 | $ mkdir fip |
| 58 | $ cp $FIPDIR/* fip/ |
| 59 | $ cp u-boot.bin fip/bl33.bin |

| 109 | and then write the image to SD with: |
| 110 | |
| 111 | .. code-block:: bash |
| 112 | |
| 113 | $ DEV=/dev/your_sd_device |
| 114 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 |
| 115 | $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444 |
