FunKey

Intro

This directory contains a buildroot external configuration for building the FunKey.

How to build it

Configure Buildroot

There is only one Funkey defconfig files in Buildroot:

$ make BR2_EXTERNAL= O=/output funkey_defconfig

Build the rootfs

Note: you will need to have access to the network, since Buildroot will download the packages' sources.

You may now build your rootfs with:

$ make BR2_EXTERNAL= O=/output

(This may take a while, consider getting yourself a coffee ;-) )

Result of the build

After building, you should obtain this tree:

output/images/
+-- boot.scr
+-- boot.vfat
+-- rootfs.ext2
+-- rootfs.ext4 -> rootfs.ext2
+-- sdcard.img
+-- sun8i-v3s-licheepi-zero-dock.dtb
+-- sun8i-v3s-licheepi-zero.dtb
+-- u-boot.bin
+-- u-boot-sunxi-with-spl.bin
`-- zImage

How to write the SD card

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 with "dd":

$ sudo dd if=/output/images/sdcard.img of=/dev/sdX

Insert the SDcard into your Funkey board, and power it up. Your new system should come up now and start two consoles: one on the serial port on the P1 header, one on the LCD output where you can login using a USB keyboard.
