+Libre Computer Le Potato (AML-S905X-CC)
+
+Intro
+=====
+
+Libre Computer "Le Potato" is a low cost SBC based around an Amlogic
+s905x SoC (quad A53), 2GB DDR3, Mali-450:
+
+https://libre.computer/products/aml-s905x-cc/
+
+How to build it
+===============
+
+Configure Buildroot:
+
+ $ make lepotato_defconfig
+
+Then you can edit the build options using
+
+ $ make menuconfig
+
+Compile everything and build rootfs image:
+
+ $ make
+
+Note: you will need to have access to the network, since Buildroot
+will download the packages' sources.
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+output/images/
++-- amlogic-boot-fip
++ +-- axg.inc
++ +-- build-fip.sh
++ +-- g12a.inc
++ +-- gxbb.inc
++ +-- gxl.inc
++ `-- lepotato
++ +-- acs.bin
++ +-- acs_tool.py
++ +-- aml_encrypt_gxl
++ +-- bl21.bin
++ +-- bl2.bin
++ +-- bl301.bin
++ +-- bl30.bin
++ +-- bl31.img
++ +-- blx_fix.sh
++ `-- Makefile
++-- boot.vfat
++-- extlinux
++ `-- extlinux.conf
++-- fip
++ +-- u-boot.bin
++ +-- u-boot.bin.sd.bin
++ +-- u-boot.bin.usb.bl2
++ `-- u-boot.bin.usb.tpl
++-- Image
++-- meson-gxl-s905x-libretech-cc.dtb
++-- rootfs.ext2
++-- rootfs.ext4 -> rootfs.ext2
++-- rootfs.tar
++-- sdcard.img
+`-- u-boot.bin
+
+The post-image script uses the files in the amlogic-boot-fip folder to sign
+the bootloader image before integrating it into the sdcard image.
+
+How to write the SD card or eMMC
+================================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card or eMMC with "dd":
+
+ $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the micro SDcard into your Le Potato and power it up. The console
+is on the serial line, 115200 8N1.
