=== Introduction ===

This document was written and tested with the software/hardware combination described in the history table above. However, it contains general concepts that can be adapted on any DAVE Embedded Systems' Linux platform.

We'll explain how to program and configure a <code>SOM</code> to boot in standalone mode, without the need for a system microSD card, with the following option:
 +
* booting with Quad-SPI NOR
 +
** in this configuration the primary boot images will be fetched from Quad-SPI NOR flash storage, while the root file system will be fetched from microSD
 +
* booting with NAND
 +
** in this configuration the primary boot images and rootfs will be fetched from NAND flash storage

We'll explain how to program and configure a <SOM> to boot in standalone mode, without the need of a system microSD card or an NFS server, with threee options:
+
=== Program the Quad-SPI NOR flash ===
−
* booting with NOR and NAND internal storage
 
−
** in this configuration the primary boot images will be fetched from NOR flash storage, while the root file system will be fetched from NAND flash
 
−
* booting with NAND only
 
−
** in this configuration the whole system will boot without the need of a NOR flash storage, all images and the root file system will be fetched from NAND flash
 
−
* booting with eMMC only
 
−
** in this configuration the whole system will boot without the need of a NOR/NAND flashes storage, all images and the root file system will be fetched from eMMC flash

Update to the latest u-boot version allows usage of u-boot environment variables available.
+
First of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project#Petalinux_build | here]]. Alternatively you can download binaries from [https://mirror.dave.eu/desk-xz-l/ mirror] and install it on microSD or into <code>tftpboot</code> directory in your host device.
  
 +
Then, boot the board with the microSD card and stop the automatic boot process of U-Boot in order to access the console.

====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>)
 
−
* copy the related u-boot imx image file on nfs /home/root (for example)
 
−
* execute kobs-ng passing the parameters for flashing u-boot on NAND

==== ext4 partition ====
 
−
For using an <b>ext4</b> partition also for boot files, it is possibile to change the formatting script:
 
−
 
 
−
{ echo ${boot_start},${boot_size},'''83''',-; echo ${rfs_start},${rfs_size},83,-; } | sfdisk --force ${node}
 
−
 
 
−
and formatting the first partition using ''mkfs.ext4''
 
−
 
 
−
  mkfs.ext4 -F ${node}${part}1 -Lboot
 
−
 
 
−
then, the u-boot <code>environment</code> has to be properly configured:
 
−
 
 
−
<pre class="workstation-terminal">
 
−
=> setenv mmc_loadk 'ext4load mmc ${mmcdev}:1 ${loadaddr} ${bootfile}'
 
−
=> setenv mmc_loadfdt 'ext4load mmc ${mmcdev}:1 ${fdtaddr} ${fdtfile}'
 
−
=> setenv mmc_loadsplash 'ext4load mmc ${mmcdev}:1 ${loadaddr} ${splashfile}; cp.b ${loadaddr} ${splashimage} ${filesize}'
 
−
=> saveenv

Standalone boot[edit | edit source]

This document was written and tested with the software/hardware combination described in the history table above. However, it contains general concepts that can be adapted to any DAVE Embedded Systems' Linux platform.


200px-Emblem-important.svg.png

The following programming examples are intended for laboratory usage or for preliminary deployment strategy.

A complete deployment strategy has to be carefully identifiyed taking into account the overall arguments like: boot speed, safe boot, recovery mechanisms, watchdog supervisor, etc.

We'll explain how to program and configure a SOM to boot in standalone mode, without the need for a system microSD card, with the following option:

  • booting with Quad-SPI NOR
    • in this configuration the primary boot images will be fetched from Quad-SPI NOR flash storage, while the root file system will be fetched from microSD
  • booting with NAND
    • in this configuration the primary boot images and rootfs will be fetched from NAND flash storage

Program the Quad-SPI NOR flash[edit | edit source]

This chapter is compatible with BORA, BORA Xpress and BORA Lite platforms, but below there is log for BORA Xpress SOM.

First of all, create a bootable microSD card as described here. Alternatively you can download binaries from mirror and install it on microSD or into tftpboot directory in your host device.

Then, boot the board with the microSD card and stop the automatic boot process of U-Boot in order to access the console.

Program the NAND flash[edit | edit source]

This chapter is compatible with BORA Lite SOM.

First of all, create a bootable microSD card as described here with config_boralite_nand_usd configuration file, and install wic binary on microSD. Then create artifact to install on NAND flash with config_boralite_nand configuration file, as described here, and save the BOOT.BIN and dave-image-devel-zynq-generic.tar.gz artifact into the first partition of microSD.

In this case BOOT.BIN binary that came from to config_boralite_nand_usd and config_boralite_nand are different, so save it with different name. Alternatively you can download binaries from mirror and install on microSD.

Then, install the following files into the microSD first partition:

  • BOOT.BIN. This binary come from to config_boralite_nand_usd configuration file, and need to install on microSD
  • boot.scr
  • desk-xz7-l-1.0.1_boralite_nand_BOOT.BIN.EXTENDED. This binary come from to config_boralite_nand configuration file, and has to be installed on NAND flash
  • desk-xz7-l-1.0.1_boralite_nand_dave-image-devel-zynq-generic.tar.gz
  • image.ub

  • delete all partition on NAND flash memory
