+====== 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>
