 This file system is very small and can be installed to the NAND flash on uSomIQ. It is not that small like Angstrom minimal distribution (~20M), but will require around 75M on the flash. However it is a real Debian system with apt-get utility installed.

 ===== Install Debian to NAND =====
+Here you will learn how install Debian to a UBIFS partition on a uSomIQ system on module.
+) Install Ubuntu or Debian to a SD card as described in the previous step
+) Download and extract a small Debian file system as described [[#root_file_system_for_nand]]
+You will have an archive debian-7.1-bare-armhf-2013-08-25.tar after extracting. Place this archive to the SD card with OS installed in the previous step.
+) Boot the board with the SD card to u-boot and issue the following commands:
+<code>
+nand erase.chip
+mmc rescan
+fatload mmc 0 0x81600000 MLO
+nand write 0x81600000 0 20000
+nand write 0x81600000 20000 20000
+nand write 0x81600000 40000 20000
+</code>
+Load the u-boot image u-boot.img to NAND. Note that we use the actual size of the u-boot.img file in Hex. If your file has a different size then update this number
+<code>
+fatload mmc 0 0x81600000 u-boot.img
+nand write 0x81600000 80000 57d74 # <- this is the actual size of the u-boot.img file in Hex
+</code>
+Load the kernel image zImage to NAND. Note that we use the actual size of the zImage file in Hex. If your file has a different size then update this number
+<code>
+run loaduimage
+nand write ${loadaddr} 280000 2B08f8 # <- this is the actual size of the zImage file in Hex
+</code>
+) Boot farther to OS
+) Prepare a UBIFS partition
+For more information visit: [[http://processors.wiki.ti.com/index.php/UBIFS_Support]]
+Preparing NAND partition for modules with 256MB
+<code>
+ubiformat /dev/mtd7 -s 2048 -O 2048
+ubiattach /dev/ubi_ctrl -m 7 -O 2048
+ubimkvol /dev/ubi0 -s 235MiB -N rootfs
+mount -t ubifs ubi0:rootfs /mnt
+</code>
+Preparing NAND partition for modules with 512MB
+<code>
+ubiformat /dev/mtd7 -s 2048 -O 2048
+ubiattach /dev/ubi_ctrl -m 7 -O 2048
+ubimkvol /dev/ubi0 -s 450MiB -N rootfs
+mount -t ubifs ubi0:rootfs /mnt
+</code>
+) Install the file system to the UBIFS-partiotion
+<code>
+cd /mnt
+tar xf <path to image>/debian-7.1-bare-armhf-2013-08-25.tar
+sync
+</code>
+) Enable the Serial login
+Edit the file /mnt/etc/inittab as described for the SD card installation.
+) Enable Network
+Edit the file /mnt/etc/network/interfaces as described for the SD card installation.
+) Remove the SD card and reboot the board
