| uboot4extlinux-a13-olinuxino installation instructions:                       |
+-------------------------------------------------------------------------------+
| To boot with u-boot you will need to do two things:                           |
| - First you will need to install u-boot to the storage device (like           |
|   a microSD) you will be booting from. You can consult the Parabola           |
|   installation instructions to know which storage devices are                 |
|   supported.                                                                  |
| - Then you will need to read and potentially modify the                       |
|   /boot/extlinux/extlinux.conf configuration file to tell u-boot              |
|   from which kernel to boot, and various other settings related to            |
|   booting (like LVM or disk encryption settings).                             |
|                                                                               |
| To install or upgrade u-boot you can use similar commands:                    |
|     cd /usr/lib/u-boot/uboot4extlinux-a13-olinuxino                           |
|     sudo ./install-uboot4extlinux.sh <path/to/block-device>                   |
|                                                                               |
| For instance if the microSD you (will) boot from is available at              |
| /dev/mmcblk0 you can use the following commands:                              |
|     cd /usr/lib/u-boot/uboot4extlinux-a13-olinuxino                           |
|     sudo ./install-uboot4extlinux.sh /dev/mmcblk0                             |
|                                                                               |
| Instead if the microSD is available at /dev/sdb you can use the               |
| following commands:                                                           |
|     cd /usr/lib/u-boot/uboot4extlinux-a13-olinuxino                           |
|     sudo ./install-uboot4extlinux.sh /dev/sdb                                 |
|                                                                               |
| When this is done you'll need to create and/or modify the                     |
| /boot/extlinux/extlinux.conf configuration file.                              |
|                                                                               |
| There is an example file for that at                                          |
| /usr/lib/u-boot/uboot4extlinux-sunxi/extlinux.conf                            |
