This directory contains a buildroot-based external configuration for
|
2018-02-25 19:07:30 +00:00
|
|
|
building the FunKey.

How to build it
|
|
|
|
|
===============
|
|
|
|
|
|
|
|
|
|
Configure Buildroot
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
There is only one Funkey defconfig files in Buildroot:
|
|
|
|
|
|
2019-03-24 22:24:40 +00:00
|
|
|
$ ./fun funkey_defconfig
|
2018-02-25 19:07:30 +00:00
|
|
|
|
|
|
|
|
Build the rootfs
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
Note: you will need to have access to the network, since Buildroot
|
|
|
|
|
will download the packages' sources.
|
|
|
|
|
|
2019-03-24 22:24:40 +00:00
|
|
|
You may now build your FunKey with:
|
2018-02-25 19:07:30 +00:00
|
|
|
|
2019-03-24 22:24:40 +00:00
|
|
|
$ ./have fun
|
2018-02-25 19:07:30 +00:00
|
|
|
|
|
|
|
|
(This may take a while, consider getting yourself a coffee ;-) )
|
|
|

Result of the build
|
|

|
|
-------------------
|
|
|
|
|
|
|
|
|
|
After building, you should obtain this tree:
|
|
|
|
|
|

|
|
|

|

|
|
|
|

+-- rootfs.ext2
|
|

|
|
+-- rootfs.ext4 -> rootfs.ext2
|
|
|
|
|

How to write the SD card
|
|
|
|
|
========================
|
|
|
|
|
|
|
|
|
|
Once the build process is finished you will have an image called
|
2019-03-24 22:24:40 +00:00
|
|
|
"sdcard.img" in the FunKey/output/images/ directory.
|
2018-02-25 19:07:30 +00:00
|
|
|
|
|
|
|
|
Copy the bootable "sdcard.img" onto an SD card with "dd":
|
|
|
|
|
|
2019-03-24 22:24:40 +00:00
|
|
|
$ sudo dd if=<Funkey directory>/FunKey/output/images/sdcard.img of=/dev/sdX
|
2018-02-25 19:07:30 +00:00
|
|
|
|
2019-03-24 22:24:40 +00:00
|
|
|
Alternatively, you can use the Etcher graphical tool to burn the image
|
|
|
|
|
to the SD card safely and on any platform:
|
|
|
|
|
|
|
|
|
|
https://etcher.io/
|
|
|
|
|
|
|
|
|
|
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.
