FunKey

Intro

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

How to build it

Configure Buildroot

There is only one Funkey defconfig files in Buildroot:

$ ./fun 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 FunKey with:

$ ./have fun

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

Result of the build

After building, you should obtain this tree:

FunKey/output/images/
+-- boot.scr
+-- boot.vfat
+-- rootfs.ext2
+-- rootfs.ext4 -> rootfs.ext2
+-- sdcard.img
+-- sun8i-v3s-funkey.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 FunKey/output/images/ directory.

Copy the bootable "sdcard.img" onto an SD card with "dd":

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

Alternatively, you can use the Etcher graphical tool to burn the image to the SD card safely and on any platform:

Once the SD card is burned, insert it into your FunKey board, and power it up. Your new system should come up now and start a console on the UART0 serial port.
