#U-boot, in turn, reads from the NAND memory the uImage, the bitstream, the DTB, and copies them into the SDRAM memory
#U-Boot starts the Linux kernel
#Finally, the Linux kernel mounts the root filesystem (<code>initramfs</code>) from the SDRAM memory and starts user-space applications and deamonsdaemons. It is worth remembering that <code>mtd0</code>,<code>mtd1</code>, and <code>mtd2</code> are used as raw partitions while <code>mtd3</code> is associated with a block device in order to mount a filesystem.
To setup this configuration, several operations need to be carried out. They are detailed in the following sections. It is assumed that the SOM can boot from the NOR flash. If not, please see [[Restoring_U-Boot_on_SPI_NOR_flash_(BELK/BXELK)|this page]].
