Now that all the boards have been converted to use genimage, the old
instructions on how to partition and write an SD card are useless.

How to write the SD card - other boards

=======================================





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

    4 heads, 16 sectors/track, 119168 cylinders, total 7626752 sectors

    Units = sectors of 1 * 512 = 512 bytes

    Syncing disks.



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





Finish

======



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