Intro
|
|
=====
|
|
|
|
This is a open hardware board,
|
|
see https://www.olimex.com/Products/OLinuXino/open-source-hardware
|
|
|
|
How to build it
|
|
===============
|
|
|
|
$ make olimex_a20_olinuxino_lime_defconfig
|
|
|
|
Compile everything and build the rootfs image:
|
|
|
|
$ make
|
|
|
|
Result of the build
|
|
-------------------
|
|
|
|
After building, you should get a tree like this:
|
|
|
|
output/images/
|
|
+-- rootfs.ext2
|
|
+-- rootfs.ext4 -> rootfs.ext2
|
|
+-- sun7i-a20-olinuxino-lime.dtb
|
|
+-- u-boot.bin
|
|
+-- u-boot-sunxi-with-spl.bin
|
|
`-- zImage
|
|

How to write the SD card
|
|
========================
|
|
|
|
|
|
Prepare the SD card
|
|
-------------------
|
|
|
|
Erase existing stuff, and create an unique Linux partition with `fdisk`.
|
|
|
|
# fdisk /dev/sdX
|
|
Command (m for help): o
|
|
Building a new DOS disklabel with disk identifier 0xf9e1616a.
|
|
Changes will remain in memory only, until you decide to write them.
|
|
After that, of course, the previous content won't be recoverable.
|
|
|
|
Command (m for help): n
|
|
Partition type:
|
|
p primary (0 primary, 0 extended, 4 free)
|
|
e extended
|
|
Select (default p): p
|
|
Partition number (1-4, default 1): 1
|
|
First sector (2048-7626751, default 2048): 2048
|
|
Last sector, +sectors or +size{K,M,G} (2048-7626751, default 7626751):
|
|
Using default value 7626751
|
|
|
|
Command (m for help): p
|
|
|
|
Disk /dev/sdX: 3904 MB, 3904897024 bytes
|
|
4 heads, 16 sectors/track, 119168 cylinders, total 7626752 sectors
|
|
Units = sectors of 1 * 512 = 512 bytes
|
|
Sector size (logical/physical): 512 bytes / 512 bytes
|
|
I/O size (minimum/optimal): 512 bytes / 512 bytes
|
|
Disk identifier: 0xf9e1616a

Command (m for help): w
|
|
The partition table has been altered!
|
|
|
|
Calling ioctl() to re-read partition table.
|

Copy images on the SD card
|
|
--------------------------
|
|
|
|
# dd if=output/images/rootfs.ext2 of=/dev/sdX1
|
|
# dd if=output/images/u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
|
|
|
|
|
|

|
|
|
|
Eject the SD card, insert it in the A20-OLinuXino-LIME board, and power it up.
