This is a Fedora remix based on the F24 LXDE spin.  It uses the Linaro 
kernel, since many of the DragonBoard 410c (db410c) specific patches are not 
yet upstream, and therefore not in the Fedora kernel.  This remix also 
includes db410c firmware (for graphics, wireless, etc.), which are binary-only.
The firmware and license are available at:

  https://developer.qualcomm.com/download/db410c/linux-ubuntu-board-support-package-v1.1.zip

To use:

1) download the Linaro boot image:

  curl -O https://builds.96boards.org/releases/dragonboard410c/linaro/debian/16.04/boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img.gz

2) download the Linaro F24 remix image:

  curl -O https://dmarlin.fedorapeople.org/fedora-arm/aarch64/Linaro-16_04-F24-remix-lxde.img.xz

3) copy the Linaro F24 remix image to an SD Card 
   (8GB or larger, using your Linux host):

  unxz Linaro-16_04-F24-remix-lxde.img.xz
  sudo dd if=Linaro-16_04-F24-remix-lxde.img of=/dev/sdX bs=4M oflag=sync status=noxfer
  (where sdX is the device name of the SD Card)

4) insert the SD Card into the db410c, and boot to fastboot mode.

5) unzip and boot the Linaro boot image with an alternate command line, i.e.,

  gunzip boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img.gz
  sudo fastboot boot \
    -c "root=/dev/disk/by-uuid/1e529f86-88e7-40dc-b290-d7b846da4b4a rw rootwait console=ttyMSM0,115200n8" \
      boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img


The above UUID matches the rootfs on the Linaro F24 remix image, so no changes
should be required if running from the SD Card.

This image boots to an LXDE desktop (user/passwd == linaro/linaro).  
The root password is 'fedora'.  For security reasons, this should be 
changed on first boot.

In order to use wireless networking, set the correct MAC address for the
system:

  cat > /lib/firmware/wlan/macaddr0 << EOF
  AA:01:23:34:67:89
  EOF

where "AA:01:23:34:67:89" is replaced with the MAC address for the device.

Reconfigure the system and reboot to fastboot, then repeat the fastboot
command (above) to reboot the system.

Once fastboot completes, the fastboot USB cable may be removed and a USB 
keyboard/mouse may be connected to the db410c for desktop use.

The image should reboot to an LXDE desktop and the onboard wireless networking
should also work.

This is image largely untested, and probably has some issues.


-----

There is also a rootfs-only image that can be flashed to eMMC.  This image 
uses the boot partition from the Debian release, so that must be installed 
first.

NOTE: This image will _replace_ the previous rootfs image.  Any previous data
and settings on the rootfs will be lost.  Only do this after backing up the
current rootfs contents.

Download the rescue image and reflash the partitions for Linux:

  curl -O https://builds.96boards.org/releases/dragonboard410c/linaro/rescue/16.02/dragonboard410c_bootloader_emmc_linux-46.zip

  mkdir dragonboard410c_bootloader_emmc_linux-46
  pushd dragonboard410c_bootloader_emmc_linux-46

  unzip ../dragonboard410c_bootloader_emmc_linux-46.zip

  sudo ./flashall

  popd

Download and flash the boot image:

  curl -O https://builds.96boards.org/releases/dragonboard410c/linaro/debian/16.04/boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img.gz

  gunzip boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img.gz

  sudo fastboot flash boot boot-linaro-jessie-qcom-snapdragon-arm64-20160428-83.img

Download and install the Linaro F24 remix rootfs:

  curl -O https://dmarlin.fedorapeople.org/fedora-arm/aarch64/Linaro-16_04-F24-remix-rootfs.img.xz
  unxz Linaro-16_04-F24-remix-rootfs.img.xz

  sudo fastboot flash rootfs Linaro-16_04-F24-remix-rootfs.img

Power off the db410c, disconnect fastboot USB cable, connect keyboard/mouse, 
and power on.

The image should boot to an LXDE desktop.  

Set the correct MAC address for the device as described earlier, then reboot.

The image should reboot to an LXDE desktop and the onboard wireless networking
should also work.
