====== Flash SD ======

The ''quimesis_imx6dl_quimbrain'' defconfig from the buildroot-quimesis repository can be used to generate a basic Linux system running on the QuimBrain :

<code>
$ git clone ssh://dev.quimesis.be:29418/buildroot-quimesis
$ cd buildroot-quimesis
$ make O=build_quimbrain quimesis_imx6dl_quimbrain_defconfig
$ cd build_quimbrain
$ make
</code>

Once the build has succeeded, flash an SD card as follow((''<sd_device>'' is the block device of the SD card; e.g. ''/dev/sdc'')) :

  - create a rootfs partition<code>
sed -e 's/\s*\([\+0-9a-zA-Z]*\).*/\1/' << EOF | sudo fdisk <sd_device>
  d # clear the in memory partition table
  n # new partition
   # default - primary partition
   # default - partition number 1
   # default - first sector : 2048
   # default - last sector : 7744511
  w # write the partition table
  q # and we're done
EOF
</code>
  - format the //rootfs// partition in ext-2<code>
$ sudo mkfs.ext2 <sd_device>1 -L rootfs
</code>
  - copy the SPL and u-boot to the SD card<code>
 $ cd images
 $ sudo dd if=SPL of=<sd_device> bs=1k seek=1
 $ sudo dd if=u-boot.img of=<sd_device> bs=1k seek=42
</code>
  - copy the rootfs to the //rootfs// partition<code>
 $ sudo tar xvf rootfs.tar -C </path/to/rootfs/mount/point>
</code>
