ODROID-C2
|
||||
|
||||
Intro
|
||||
=====
|
||||
To be able to use ODROID-C2 board with the images generated by
|
||||
Buildroot, you have to prepare the SDCard or eMMC.
|
||||
|
||||
How to build it
|
||||
===============
|
||||
|
||||
$ make odroidc2_defconfig
|
||||
|
||||
Then you can edit the build options using
|
||||
|
||||
$ make menuconfig
|
||||
|
||||
Compile all 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/
|
||||
+-- Image
|
||||
+-- boot.ini [1]
|
||||
+-- boot.vfat
|
||||
+-- meson64_odroidc2.dtb
|
||||
+-- rootfs.ext2
|
||||
+-- rootfs.ext4
|
||||
+-- rootfs.tar
|
||||
+-- sdcard.img
|
||||
`-- u-boot.bin
|
||||
|
||||
[1] This is the ODROID-C2 configuration file used in u-boot.
|
||||
|
||||
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 SDcard into your ODROID-C2, and power it up. Your new system
|
||||
should come up now.
