+Amarula A64 Relic
+================
+
+Amarula A64-Relic is A64 based IoT device, which support
+- Allwinner A64 Cortex-A53
+- Mali-400MP2 GPU
+- AXP803 PMIC
+- 1GB DDR3 RAM
+- 8GB eMMC
+- AP6330 Wifi/BLE
+- MIPI-DSI
+- CSI: OV5640 sensor
+- USB OTG
+- 12V DC power supply
+
+Wiki link:
+https://openedev.amarulasolutions.com/display/ODWIKI/Amarual+A64-Relic
+
+Build
+=====
+
+  $ make amarula_a64_relic_defconfig
+
+  $ make
+
+build files at output/images/:
+  - sunxi-spl.bin
+  - u-boot.itb
+  - Image
+  - sun50i-a64-amarula-relic.dtb
+  - boot.vfat
+  - rootfs.ext4
+
+Write eMMC
+=========
+
+The board comes with an operating system preloaded on the eMMC.
+To replace it with the Buildroot-built system, take the following
+steps
+
+1. Connect the board UART with host and open minicom(ttyUSBx/115200N8)
+
+2. Supply 12V DC for power-on the board.
+
+3. Interrupt U-Boot by pressing enter
+
+4. Create GPT partitions
+  => mmc dev 1
+  => gpt write mmc 1 $partitions
+
+5. Connect the board USB-OTG with USB slot on the host.
+
+6. Initiate fastboot
+  => fastboot 0
+
+7. Write images from host onto eMMC using fastboot
+
+  $ cd output/images
+  $ sudo fastboot -i 0x1f3a flash loader1 sunxi-spl.bin
+  $ sudo fastboot -i 0x1f3a flash loader2 u-boot.itb
+  $ sudo fastboot -i 0x1f3a flash esp boot.vfat
+  $ sudo fastboot -i 0x1f3a flash system rootfs.ext4
+
+Update eMMC during Development
+==============================
+
+During development, reflashing the entire filesystem image at every
+change is time consuming. A useful alternative is to directly access
+over USB the filesystem stored on the eMMC, using the USB Mass Storage
+capability of U-Boot. To achieve this:
+
+1. Build U-Boot with CONFIG_CMD_USB_MASS_STORAGE=y
+
+2. Follow all 6 steps from 'Write eMMC' and mount eMMC on host
+    => mmc dev 1
+    => ums 0 mmc 1
