=== Program boot images into NAND flash ===
====U-Boot====
U-Boot on NAND flash must be programmed using NXP <code>kobs-ng</code> utility: this tool is required for writing the correct U-Boot image on NAND storing all information needed by bootrom to identify the NAND as a boot device.
Here below an example:
* boot the system via SD on NFS
* uses a rfs with <b>kobs-ng</b> utility available on it (e.g. DAVE's rfs provided with <KIT>[[DESK-MX6UL-L| DESK-MX6UL-L]])
* copy the related U-Boot image file on nfs /home/root (for example)
* execute kobs-ng passing the parameters for flashing U-Boot on NAND

=== Program root file system into NAND flash ===
* Boot boot the system via SD or NFS as described in the e [[(<KIT>)#Quick_start_guideDESK-MX6UL-L/General/Booting_from_NFS|Quick start guideBooting from NFS]]* By by default, the NAND is already partitioned to allow booting from NAND-only (see next section) and, thus, some partitions are reserved for u-boot and kernel images. Here we won't modify this default configuration. The [[Memory Tecnology Device (MTD)|MTD]] partitions can be dumped with <code>/proc/mtd</code> (the partition's name should be self-explanatory)
