6 WeTek Core2 is an Android STB based on the Q200 reference design with
7 the following specifications:
9 - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
12 - 10/100 Realtek RTL8152 Ethernet (internal USB)
13 - HDMI 2.0 4K/60Hz display
14 - 2x USB 2.0 Host, 1x USB 2.0 OTG (internal)
17 - SDIO Wifi Module, Bluetooth
18 - Two channel IR receiver
25 $ export CROSS_COMPILE=aarch64-none-elf-
26 $ make wetek-core2_defconfig
32 Amlogic does not provide sources for the firmware or the tools needed
33 to create the bootloader image, and WeTek has not publicly shared the
34 precompiled FIP binaries. However the public Khadas VIM2 sources also
35 work with the Core2 box so we can use the Khadas git tree:

50 Go back to mainline U-Boot source tree then:

57 $ cp $FIPDIR/gxl/bl21.bin fip/
