* Boot the system via SD or NFS as described into the [[System_boot_and_recovery_via_microSD_card_(BELK/BXELK)|System boot and recovery via microSD card]] and [[Booting_the_system_via_NFS_(BELK/BXELK)|Booting the system via NFS]]
* By default, the NAND is already partitioned to allow booting from NAND-only (see next section) and, thus, some partitions are reserved for FSBL, 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)

In U-Boot environment please set the following variables in order to be able to boot from NOR + NAND
==Use case #2==
===Introduction===
This configuration makes use the most common partitioning schemes for booting completely from NAND flash, that is:
*The NAND flash acts as boot memory and root file system storage; as such, it contains
**bootrom header and FSBL (or header+U-Boot SPL)
**U-Boot
**U-Boot redundant environment
**Even though these images are not strictly required to boot the system, the NOR flash also contains:
***The Linux kernel image
***The Linux Device Tree Blob (DTB)
***The bitstream file for the Programmable Logic (PL).
***The read/write UBIFS root filesystem.
The resulting flash memory layout is illustrated in the following pictures.
[[File:BELK-NAND-flash-partitioning-case-boot-NAND.png|thumb|center|600px|NAND flash partitioning scheme]]
In essence, the bootstrap sequence looks like this:
*U-Boot fetches and programs the PL bitstream
*Then it fetches the Linux kernel binary images (kernel and DTB) from the on-board NAND flash memory
*The Linux kernel mount the root filesystem from a NAND partition.
====Testbed====
This configuration was tested with the following testbed:
*SOM: DBTD4111I0R
*carrier board: EVBBX0000C0R
*software: [[BELK/BXELK_software_components#BELK_4.1.0|BELK 4.1.0]]
=== Program the boot images in NAND flash===
It is assumed that the following U-Boot's environment variables are defined:
<pre class="board-terminal">
fdt_base=0x00780000
fpga_base=0x00180000
kernel_base=0x00800000
loadk=tftpboot ${loadaddr} ${bootfile}
loadfdt=tftpboot ${fdtaddr} ${fdtfile}
loadfpga=tftpboot ${loadaddr} ${fpgafile}
nand_updatek=nand erase.part kernel; nand write ${loadaddr} kernel ${filesize}
nand_updatefdt=nand erase.part fdt; nand write ${fdtaddr} fdt ${filesize}
nand_updatefpga=nand erase.part fpga; nand write ${loadaddr} fpga ${filesize}
nand_loadk=nand read ${loadaddr} kernel
nand_loadfdt=nand read ${fdtaddr} fdt
nand_loadfpga=nand read ${loadaddr} fpga
program_fpga=run nand_loadfpga;fpga load 0 ${loadaddr} 0x${filesize}
</pre>
* Update the <code>bootfile</code>, <code>fdtfile</code> and <code>fpgafile</code> environment variables to fit the filename as found inside the TFTP server.
* Program kernel and device tree on NAND flash with the following U-Boot command
<pre class="board-terminal">
Bora> run loadfpga nand_updatefpga loadk nand_updatek loadfdt nand_updatefdt
</pre>
E.g.:
<pre class="board-terminal">
Bora> run loadfpga nand_updatefpga loadk nand_updatek loadfdt nand_updatefdt

In U-Boot environment please set the following variables in order to be able to boot from NAND
<pre class="board-terminal">
nandargs=setenv bootargs ubi.mtd=7 root=ubi0_0 rootfstype=ubifs rw
nand_nand=run program_fpga nand_loadk nand_loadfdt nandargs addcons addmisc; bootm ${loadaddr} - ${fdtaddr}
